NT63 NT6735 Roadside Wych elm Spring 2008 No grid available but suitable elm has been marked with orange spray Rural Richard Buckland Article in East Scotland Branch newsletter No 16 (Spring 2008) encouraging branch members to look for white-letter.
'As stated in the article, hedges which are exclusively elm will be marked with orange paint this autumn. Sitting here in Edinburgh, I cannot say if the junction you mention has any elm, but it is highly likely, as the B6404 goes through both of these 1k squares, an there is elm all the way along it. But I was going to mark out the stretches where the hedge is exclusively elm, to help people find elm in winter.'

NT83 NT8633 (images available) 13.03.09 and 23.04.09 Egg at 10km level (2018), elm NT865327 at 2km level Rural Jill Mills and Ken Haydock Feb 18, Barry and Barbara Prater Although never removed from project, assumed outside of the range of the species until February 2018 when Ken & Jill visited the 10km for the first time and found an egg near Cornhill on Tweed on the English side. Previously they had found eggs including a hatched egg from the 2016/2017 season in the adjacent 10km square NT84 the first confirmed eggs in Scotland. 25.07.09: NT83 (NT861327) - again, nothing, although several Elms had significant leaf damage
11.07.09: I'd earlier located Elms in the adjacent 1km square. Along the B6351 there are many small-medium Elms interspersed with Ash, Oak, Sycamore, Hawthorn, Cherry, etc., either side of NT861327 for about 200m. Some leaf damage noted on some of the Elms. Because many of the accompanying trees are mature they create a sheltered, almost woodland environment and would be ideal for the butterfly. And the number of Elms represnt a good corridor for spread.
23.04.09: None seen at 1km. However, a few small Elms in field hedge in adjacent 1km square (NT8744). Also many Elms along B6351 in same tetrad (NT865327) - some photos of these are attached. Worth a good check later.
13.03.09: I went to look at the 1km squares NU0435 and NT8633. No Elms spotted I'm afraid. My plan is to re-visit them in a month or so, once any Elms have flowers/seeds and to extend my search to 2km and 10km as needed.
NT86 NT8265 Several elms
(images available)
14.06.08 NT8265 Rural Barry & Barbara Prater 27.07.09: My original target square - nothing.
11.07.09: No leaf damage evident on the one large Elm, but the small ones did have some; too windy to expect the butterflies to move much though. I will return here later.
April 09: We looked around NT 8265 and found some promising Elms, readily accessible for viewing, close to the A1. Some had a little leaf damage, but I don't know what caused it, but the best tree appeared to have almost perfect leaves. We will return in a few weeks time.
NT94 NT9544 Small/medium elms on roadside along wood edge 16.06.07 NT950441 Rural Martin Greenland No sign of eggs, pupae or suitable feeding damage

NU03 NU0435 13.03.09 and 23.04.09 NU019360 and NU010396 Rural Barry and Barbara Prater 11.07.09: NU0435 (Northumberland), Looked at Elms found previously at the 10km level. Two near Hetton North farm (NU019360) don't get much sun and are rather exposed, especially when the wind blows. Another good Elm, but isolated on the roadside at NU019366, proved negative too. Just outside this square there is a line of mature trees, including several reasonable and sheltered Elms, running east-west and so getting good sun (NT994394). This would be a good place for a colony to start up and possibly expand. I was briefly excited by what turned out to be a Small Copper fluttering around and settling on leaves. 23.04.09: No elm at 1km. Probably none at tetrad level. However, some in 10km square at NU019360 and NU010396 (this one a good size). Area doesn't look very promising though.

NY01 NY0112 No elm seen at target level, but elms at entrance to industrial estate at 10km level
(images available)
08.02.09 & 09.02.09 NY013101 Rural Liz Goodyear & Andrew Middleton Driving through Egremont a nice row of assumed planted elm at entrance to Bridge End Industrial Estate was found(also riverside elm in adjacent 10km square). Sampled but no eggs found. Drove around target 2km but no elm visible and also stopped at Longlands Lake. Although presumed to be beyond range of species the Industrial Estate Elms need to be monitored. Elm was seen in adjacent 10km to south (NY00) but probably absent from SD19 thus cutting elm link to the south?
NY02 NY0121 Elm at 10km level including an avenue of elm trees
(images available)
09.02.09 NY008221
NY063216 (old tree)
NY092247 (avenue of trees)
Rural Liz Goodyear & Andrew Middleton Much of 10km square is exposed industrialised moorland and target is on this edge. A nice bank of elm was found just outside 2km. On the east side of the 10km square, a very old tree was seen at Wrights Green and on the road into Pardshaw, an avenue of fairly exposed elm trees were found. There was at least 8 healthy trees and evidence more trees had died. No eggs were found. Although presumed to be beyond range of species all these elms need to be monitored.

(images available)
08.02.09 and 09.02.09 Rural Andrew Middleton and Liz Goodyear Drove through 10km on two occasions, and apart from one small tree at Isel, no elm was noted. Provisionally assumed that this 10km square can not support white-letter hairstreak.
NY25 NY2958 Roadside trees
(images available)
09.02.09 NY232585 Rural Andrew Middleton and Liz Goodyear Although presumed to be beyond range of species all these elms need to be monitored. Target very low, estuary edge marsh. Drove around 10km and into adjacent 10km square. Roadside elm found at NY224625 (NY26) and NY232585
NY28 NY2387 Removed from project
NY42 NY4224 Elm at 10km level

08.02.09 NY480283 and NY489282 Rural - High Altitude guidelines apply Andrew Middleton and Liz Goodyear High Altitude guidelines apply, target 505m (Low Mell Fell) but 2km level down to 200m. Drove through Penrith and along A66, elm seen in adjacent 10km and then immediately into 10km before first roundabout. Came off A66 and went into Stainton and several elm trees noted. Sampled for eggs but not found. (All these sites were at low points in the 10km). Although presumed to be beyond range of species these elms need further monitoring.

Visited by Jill Mills and Ken Haydock when 2 adults seen flitting and perching near top of Elm between 11-10am to 11-30am. The site was along the River Eden. A small quantity of elm found in a wood edge at 2km level. Single tree seen roadside at 1km level and more elm seen at 10km level in particular along B6263 between Wetheral and A69. Long length of elm also at 10km in layby which crosses the 10km at NY5058

NY61 NY6215 Little elm present NY6819 Rural village/moorland 03.11.09 Andrew Middleton & Liz Goodyear Presumed outside known range of butterfly. No elm found at 1km and unlikely on moorland sections, little elm found elsewhere. Rivers systems not connected to known colonies e.g. (Tyne valley). Majority of 10km square over c200m lowest point 130m - High Altitude guidelines apply
NY65 NY6050 Rural / High Altitude This 10km has not been visited but is in river valley of South Tyne. Originally presumed outside range of butterfly but in view of findings in NY75 (Allen Valley) has been reinstated as deserving continued monitoring. Majority of 10km square over 200m, although altitude range of South Tyne is between 130m & 230m - High Altitude guidelines apply
NY73 NY7831 Removed from project, as 10km square over 400m and presumed beyond range of species
NY74 NY7348 Some elm above river valley NY714481 Rural /High Altitude 03.11.09 & 04.11.09 Andrew Middleton & Liz Goodyear Elm found beside river valley of South Tyne, sample taken negative. Originally presumed outside range of butterfly but in view of findings in NY75 (Allen Valley) has been reinstated as deserving continued monitoring. Majority of 10km square over 250m, lowest point is 230m on River Tyne - High Altitude guidelines apply
NY91 NY9118 Not visited. Removed from project, as majority of 10km square over 300m and presumed beyond range of species, lowest point is 200m on River Balder, which connects to River Tees.

Rural village Barry and Jean Robinson, Andrew Middleton and Liz Goodyear 27.07.09: Had stopped at elm late afternoon of 25.07.09 but no activity, so returned early morning but too cool so sampled elm on field edge and a fresh egg was found on a growth joint.
10.02.09: More elm found at 1km level but no eggs found, so drove around 10km square and found a nice length of elm alongside A695. After some searching 2 old hatched eggs found on leaf scar and growth joint
22.04.09: Wych elm found at the 1km level 1 x 10m in height, 3 x 4m in height. No ova visible

Rural Martin Greenland, Liz Goodyear & Andrew Middleton 04.11.09 Continued searching 10km square for any elm not seen on previous visits and found 3 trees on wood edge, sampling found hatched egg on 2nd year growth joint!
26.07.09: Visited 10km on two occasions but never in perfect weather conditions, rain, heavy cloud and wind with just brief moments of sunshine and no activity. However, several new areas of elm were found including 2 large trees at NZ091711. Several areas of elm sampled but no eggs. There are several areas of good elm throughout sections of 10km square and with a past record in 1999 this 10km remains on our priority list of potential sites.
10.02.09: Visited target and surprised to see some elm at 1km level, sampled but no eggs found. Site is very exposed and it is felt unable to support white-letter hairstreak. Drove around 10km located Martin's elm and some more but tall elm where the only sighting from this 10km is noted.
13.06.07: Didn't visit target square, but plenty of suitable roadside elm at stated grid reference. No sign of eggs or pupae or likely feeding damage
NZ09 NZ0795 Plenty of wych elm along Forest Burn, mostly fairly small. Tree concerned was in sheltered woodland edge, larger and seeding 1 14.06.07 NZ095988 Rural Martin Greenland Possibly a new 10km square for the species (also recorded eggshells in NZ08, NZ18 & NU00 - possibly a new 100km square?)

09.07.08 elm
NZ138158 Rural Martin Greenland, Liz Goodyear & Andrew Middleton 11.02.09: Following Martin's description walked along Teesdale Path and found several elms including one medium tree and found 2 eggs (1 base of bud on tip and 1 egg on growth joint). 09.07.08: Plenty of fairly young elm along the Teesdale Way footpath from Winston bridge NZ 142163 and running right through the 1km square. In tetrad, bridge at Ovington NZ 132147 looks down on a canopy of elm. Nothing seen - probably too early. But plenty to check in the future. I would expect the species to occur somwhere in the river valley in the 1km square - only problem is locating it!

04.04.08 elm
NZ298469 Rural (riverside woodland) Barry and Jean Robinson, Liz Goodyear & Andrew Middleton 11.02.09: Following Barry & Jean's directions, elms were found throughout hillside leading down to the Wear. Small tree found close to river and sampled for eggs - 1 egg found growth joint old leaf scar.
04.04.08: 2 specimens 1 - 20 metres, growing in bankside overhanging the river Wear which was 3m below. Only able to examine the last 1m of one branch. No ova. 2. Damaged specimen- growing point had been cut off at some time in the past- resulting in side branches increased growth. About 4m tall. Examined the last metre of more than 10 branches. No ova.

Rural Barry and Jean Robinson, Liz Goodyear & Andrew Middleton 11.02.09: First found some 10km elm at the back of Teeside airport and an egg found, then found elm identified by Barry & Jean and an egg was found on the lower leaf scar on main stem just below growth joint.
25.04.08: None found at 1km level. Several English Elm of 3m to 4m height found suckering from stumps in hedge. No eggs seen

Barry and Jean Robinson, Liz Goodyear & Andrew Middleton 11.02.09: Found the elm identified by Barry and Jean but despite large quantity all out of reach. More elm including several planted trees found to west of target and after considerable searching a single egg was found concealed under a bud. 10.04.08: No Elm at 1K or 2K level 8 mature Wych Elm at in adjacent 2km at 10km level: 2 apparently dead. 1 x 30m, 4 x 20m, 1 x 12m. No ova seen
NZ70 NZ7006 NZ7006 Elm found on edge of 10km but then almost absent until a single tree in garden at 2km level (image available) 1 possible 25.07.09 hatched egg and 20.05.08 elm NZ701079 elm and NZ784055 hatched egg Rural village Martin Greenland, Liz Goodyear and Andrew Middleton 25.07.09: First watched and sampled elm close to Limber Hill Wood, no activity, so continued driving through 10km square keeping as close to the river as possible. More elm was found close to river near Glaisdale Station, elm was sampled and a hatched egg found on growth joint. At 3.30 a hairstreak was seen in the crown of an elm tree very briefly, it was later realised that Purple are not present in this part of Yorkshire? Continued to drive through 10km and realised that elm was no longer present and by the time the 2km level was reached, presumed that the 2km elm is too isolated to support wlh. The 10km record was in the same 2km square as the 2005 record but not at the same location.
20.05.08: No elm seen in 1km. Single wych elm in tetrad in garden in Ainthorpe (photo). Also some 2m English elm in hedgerow (discounted) Unable to examine, but thought unlikely to carry species due to probable isolation. Closest record of wlh in 10km square is currently NZ797048 in 2005

SD19 SD1891 No elm noted - no photos available 08.02.09 Rural Andrew Middleton and Liz Goodyear Drove south along A595 but no elm noted. Did not visit target in the Ulpha area, due to poor weather conditions and narrow roads. Elm could be present? Provisionally assumed that this 10km square can not support white-letter hairstreak.
SD51 SD5410 4 elm trees at 2km level, also roadside elm at 2km level, motorway elm at 10km level and 3 large trees beside narrow lane leading to M6.

Liz Goodyear and Andrew Middleton
01.08.09: We went to an area right in the centre of SD51 which we hadn't explored before (for some reason), called Park Hall at Charnock Richard just above the service area on the M6. This is a hotel complex surrounded by trees. Sure enough we found a likely looking elm and after waiting and watching, a WLHS was spotted high in the canopy at 1 20pm. Later we went to more elms seen at SD591163 near the river bridge at Chorley and at 5.40 in the sun we saw 3 individuals flitting round one of the elms. After that sighting, we visited the 3 elms you found at Coppull down the lane opposite the rugby ground and after only a few minutes 1 individual gave good views as it flew from the elm over the lane and back again. Absolutely fantastic! JM/KH
28.07.09: Came into 10km square from north and started driving towards Chorley but whilst driving through Astley, saw numerous roadside elms and since it was raining decided to sample for eggs, 1 fresh egg was found on a new growth joint.

30.06.09: watched M6 in sub optimum conditions, with no activity
08.03.09 Revisited 10km square and took route to M6 where elm had been seen whilst driving through. Small lane produced three large trees, no eggs found but must be revisited during flight period. 07.02.09: Visited SD51 and found little elm at 10km but drove through tetrad and found some large roadside elms just into the 2km square by a hotel/house.
07.07.07: 4 elms found equally spaced along trimmed hawthorn hedgerow. Heighest tree 7 metres approx.Other 3 trees 5 metres approx. No sign of elm at 1km level but present at 2km - no adults seen but weather dire at moment (Lancashire )

Urban green space Jill Mills and Ken Haydock, Liz Goodyear & Andrew Middleton 08.11.09: Following on from our first ever WLHS egg spotting on Friday and really hooked as you said, we went to the target square at the cemetary in Farnworth and WOW...FOUND EGGS at 74543 06461. Can't believe it!
11.07.09: Bolton SD 70...!!! Hooray!!! Visited this morning and...after 30 mins we saw 3 individuals flying above the tree across the road from Queen's park. One was spotted first perched on a leaf high in the canopy and then it flitted upwards and was joined by the other two. That was at 9 45am.
30.06.09: Weather conditions now poor, and drove into Bolton along A673, the road is lined with massive elms which fizzle out as you reach SD51. However, more elm found around Queens Park, found a empty pupal case and hatched egg, which meant they were flying!
08.03.09: Revisited 2km and found some roadside elm along 666 next to convenient layby. No eggs nor at cemetary unfortunately. 07.02.09: Walked around Moses Gate Country Park but no elm found, but some elm found on edge of local cemetary by public footpath. Just outside 2km, row of elm seen at back of builders yard. General elm levels in 10km square appeared very low

03.11.09: revisited but no improvement on previous visit. There are records in adjacent 10km square but the habitat quality changes although northern section of 10km forms part of Wenning valley.
12.02.09: Drove through 10km square coming in along B6480, and targetted the lowest points. Single elm found at Clapham station (SD732677) and a bank of elm on the edge of a cliff face (B6480 to Settle). Both sampled but no eggs found but worth monitoring during flight period.
14.03.07: No elm found in SD7763; tetrad not fully searched. A few small wych elms in small woodland at SD 785631. No eggs found
SD77 SD7874 SD7874 4 small roadside wych elms in hamlet 14.03.07 SD784756 rural upland hamlet - altitude 280m. High altitude guidelines apply Martin Greenland No elm seen in SD7874. No eggs found (presumed outside known range of the species).
Lowest point 140m on River Doe at Ingleton on the west side of the 10km square but altitude rapidly increases.

1 18.08.08 SD830495 Rural Martin Greenland Good quantity of wych elm in woodland bordering Stock Beck at road bridge. (10km record: didn't visit the 1km square or tetrad at all) Egg on branch accessed from bridge (tree photographed). First success in 3 visits to site over 3 different years. Probably the furthest up Ribbledale (to check)

25.08.08: Further to Rob Foster's notes from 2007, I don't expect this square to yield wlh. I did check elms on 22/08/08 at Grassington SD998638 and Kirkby Malham (just in SD86) to no avail. There are no records this far up the rivers Aire or Wharfe - closest is Skipton 5 miles away. Martin

Unfortunately it was very breezy and no sheltered elm was found. 10km needs continued monitoring
25.07.07: Presumed outside known range of the butterfly but worth continued monitoring

Through binoculars Andrew was able to see a white-letter flying over the elm which was confirmed by Liz.
2007: Elm present at 10km level. "SE08 is an interesting square: apart from being unable to rerecord a 1997 sighting at Aysgarth Falls, I've searched elms along the road between West Witton and Wensley (effectively what the revised method asks for) in 2005 & 2006 without success. But it's not far to my closest wlh record at Spennithorne Wood last year - so I wouldn't be surprised if they turn up in SE08 soon." - Martin Greenland

02.08.08 and April 2008 SH545566 Rural (target 1km is in mountains so high altitude guidelines apply) Helen Bantock and Andrew Middleton January 2010: Reinstated in view of recent egg finds in north Wales, although it was felt there is no suitable elm at 10km.
02.08.08: searched all roads and walked 2km area - well-wooded valley to NW but alder and hazel etc - one small roadside elm, previously located by Helen checked for eggs, - negative. Hillside woods may hold some wych elm.
April 2008: Before setting out, Andrew had suggested that the Afon (river) Gwyrfai might be the place to look in SH55. The chosen monad was at the summit of a mountain and I did not climb it! It was raining as I made my way and the mountain views dramatic. As I passed the lake at the start of the Afon Gwyrfai, I decided to stop and explore a bit by foot, having glimpsed a likely tree as I tried to make sure I didnt have any head long collisions on the narrow, winding road. This was a Wych Elm at an altitude of 120m. Further along the road, a mile or so away, I parked again and before exploring further spoke to a farmer's wife who was waiting for a bus. She said that there used to be a lot of elms in the forest at the back of her farm, but Dutch Elm disease had affected them and they had been felled and used to keep the family warm one winter! Further exploration of the river side was not fruitful, but I feel a return visit in better weather could just find more elm. Clearly, if elm was fairly abundant in the past, there is a hope that the White letter Hairstreak is still present.

Helen Bantock 14.07.08: After regular visits, adults seen through telescope and confirmed!
19.07.07: no sightings at 1 or 2km level. 16.07.07: It was dull and cloudy first thing and sporadic sun appeared around 9.30am.I went first to the elms in the SH61 monad outside Barmouth.Although sunny,and temps up to 16 degrees ,it was still windy and I just wonder if this site is not sheltered enough.I saw nothing between 10 and 10.45am. Further up the road there is a big dead elm and lots of new growth, but all under a canopy of other trees. So I returned through Barmouth and looked at the elms by the road at SH611163, just outside the tetrad. I arrived just on 11 am, and the sun was intermittent, but quite strong.In 20 minutes, I had four or five sightings of dark butterflies at the top of a big lime which overlooks the elms . There is another lime behind it and a sycamore and ash but no oak nearby. The butterflies had the typical hairstreak fidgety flight, but I saw no spiralling. I watched one disappear into the leaves of a branch below the crown of the tree and re-emerge briefly, but then it all went quiet and nothing more happened in the next 45 minutes.
06.05.07: I went back to Barmouth, as when I drove to Harlech 10 days ago, I thought I saw elms by the road where I hadn't seen them before, but I was too tired to stop . In fact, there are at least 9 elms in SH6317! And to think I parked in the lay by where I found them when I walked all over the monad at the beginning of April. I cant think why I didn't see them before, but just shows you have to go back to check. The wind had blown a lot of seed heads down, many of which had feeding damage. However, I couldn't see any WLH larvae or eggs using binos and only the very lowest branches were accessible. Previously, elms found in three other one km squares: SH6918, SH6717 and SH6516. No eggs seen. But only the elm in SH6918 was reachable and this revealed a larva of, as yet, unknown species but not WLH.
SH62 SH6429 Elm found at 10km level. Four big elms in flower plus more spindly growth of four or five boles -looked like suckers. Also in flower (images available) 1 July 2009 adults at 10km level on several dates

SH606226 Rural, on the edge of a wood and along a river valley (target 1km is in mountains so high altitude guidelines apply) Helen Bantock and Andrew Middleton August 2009: The river Ysgethin flows down from the Rhinogs to the sea at Talybont. Within SH6022 there is elm along the road leading to Pont Fadog and two big elms about 50 metres lower down the river growing on the south side of the river bank.The elms are hard to view because of the steepness of the river bank and the large ash trees surrounding them. Beech and some oaks are also present, but the oaks are mostly lower down the river and there is a Purple Hairsteak territory in SH5921, about 100 metres up from the bridge at Talybont. The best viewing area was visited three times between 13.7.08 and 25.07.09. On 18.07.09, viewing was between 12.15 and 2pm.It was cloudy with some bursts of sun and the temps was 18deg C.A dark butterfly was seen flying from one ot the three tallest ash trees on the south side of the river towards the elms, but because of the topography the elm was not visible .Even with a telescope, the butterfly was too distant to identify its markings. On 25.07.09 viewing was between 10.15 and 11.30am. It was sunny but with occasional clouding over and the temps 20 deg C. Between 10.45 and 11.15am there were three sightings of dark butterflies crossing towards the elm from the same ash as on the 18.07.09. In view of the timing and the fact that the butterflies were seen in the same place, I believe they were White letter Hairstreaks. Purple hairstreaks are usually sedentary during the day and those I have seen along this river are active from 5-6pm and have only been seen by me at the oaks near the bridge , which is at least a kilometre and a half away from Pont Fadog. 01.08.08: (also 3 Aug 08 in poorish weather) Poor weather - visited c5 elms at top of valley; viewing difficult but WLH possible. Purple hairstreaks flying well 5pm but managed to leave binoculars behind.
31.03.07: The selected monad for SH62 is SH6429 and this is in a high, treeless area, as is the tetrad. Searches in SH6128 have been negative. Four big elms in flower-look to be at least 80 years old. A few yards away, down the bank, there was some more spindly growth of four or five boles -looked like suckers. These were also in flower. Altitude: 168metres
SH65 SH6653 Roadside elm

April 2008 SH652522 Rural (target 1km is in mountains so high altitude guidelines apply) Helen Bantock and Andrew Middleton 02.08.08: poor weather; large elm plus 2-3 smaller elms; weather unsuitable for observations although 3 purple hairstreaks on elm was a new 10km record. Egg search negative but large canopy out of reach. Generally low levels of elm encountered along valley roads.
April 2008: My first visit concentrated on that grid reference and I walked all along the river, but could find no trace of any elm. I had to drive on elsewhere that day and as I drove up the steep mountain roads, I thought I glimpsed some elm, but there was nowhere to stop. A few days later, I returned and was able to confirm the elm sighting at SH652522. There were several trees on either side of the road growing by a narrow river on a steep hillside (altitude 137metres). I could see no fruits, but the leaves and tree trunk were typical of Wych Elm. Interestingly, this one km square is only a kilometre down the road from the selected monad ( where I looked without success). However, because the monad is in tetrad 65R and the one where I found the elm is in tetrad 65L, the elm will count as being at the 10km level.

13.08.07 and 04.08.08 SH742004 Mountain/Moorland Andrew Middleton 04.08.08: weather poor, egg search negative, but tree fairly large and healthy
13.08.07: Searched the tetrad and monad for elms from the road without luck. Driving across the 10km, it is dominate by mountain and moor, with no obvious presence of elm. The monad itself is low-lying, mostly below 10m and could do with a walking search because there may be some elm at 1 or 2km level. One prospective target was a single large healthy elm along a flailed elm hedge at SH742004, 200m outside the monad. Flailed elm hedge also noted at SH767027.

An egg was also found in SH75.
09.03.09: Looked at target and found elm to be at quite low levels and unlikely to support wlh? Little elm noted at 10km level 09.02.08: Elms found in target square - 1km level:

Found a huge elm at 1km level in grounds of N Wales Police headquarters which must be watched in the flight period. Took a walk alongside Fairy Glen Riverside walk and some elm found just outside 1km level at 10km and a hatched egg was found . Whilst driving out of target found Wynn Gardens which is full of elm (including some hybrid 'camperdown' elms). Later realised that this was the park where Jan Miller showed Prince Edward a nectaring white-letter last summer so adult found at 2km level!

Andrew Middleton and Liz Goodyear 22.07.09: Drove in from west and decided to look at the southern section of the 10km square along B4389 where elm in adjacent 10km square had been seen on previous visit. After going through New Mills decided to follow river and found a large elm by a stream and buildings, then returned down lane to where a good length of elm had been seen but it was overcast and rain threatened. In a brief moment of brightness a possible white-letter was seen to flick around crown of an elm but later 2 fresh eggs were found on some sampled elm. One on the very tip on a leaf scar (leaf lost) and one on the axil of a side shoot.
13.08.07: Drove the roads in 1km and 2km (all over 250m) - no elm seen as per through the SW quarter of this 10km. However, 30m of short Wych-elm at SJ040013 worth a look in the flight season, c20m outside tetrad at 230m altitude. Also small scraps of elm at SJ045016, and one moderate elm at SJ047012. Small elm also SJ091012 altitude 160m. The adjacent 10km to the east, SJ10, begins to hold more elms, just outside the 10km along the B4389, eg several large elms SJ102050, and one very large elm at SJ 109073. So there should be some good elms to be found somewhere in the east or NE of SJ00 10km target square.

Rural Helen Bantock, Liz Goodyear & Andrew Middleton 10.03.09: This was probably one of our hardest targets, knowing that there were several recent records we couldn't give up! Found several areas of elm at 2km level but much out of reach and what was sampled did not have any eggs. This target should still be watched for adults though. Drove south west through 10km and noted many areas of quality roadside elm, but again much out of reach. Eventually only metres inside the 10km level a row of accessible elm was found and an egg was found at last.
17.05.08: Plenty of Elm in the hedgerow along the B5429. And a big elm just above a small woodland glade that runs by the river near Pen y felin, in the 2 km square at SJ15442 69788 at 160m (according to my GPS). I just could not get to the small patch of woodland within the one Km square.

14.12.07: Drive / track leading from Milton Green to Calveley Hall, 300m long 10m wide strip of wood by the side of the track from SJ459587 to SJ456587 more tham 50 large and medium size elm trees mixed with other deciduous trees At 10km level, elm hedgerow in Milton Green an two medium size elm trees SJ461587. Before I arrived at the target square SJ4558, I had nearly driven the length of the 10km square and from were I had parked walked several miles with my dog along minor roads, footpaths and bridle paths without seeing any elm trees in the hedgerows or woods, until I arrived at Milton Green and the target square, the track runs from East to West so the strip of wood should be in the sun for most of the day. I am not sure which type of elm they are, I don't think they are Wych Elm as the bark and shape is different to what I see on my own patch. The quantity of trees may be large but it could be a bit isolated, but you can park at the start of the track so it should be an easy location to check in the summer.

Urban town 290m. Peak District (target 1km is over 400m throughout - high altitude guidelines apply). Rob Foster & Martin Greenland 31.07.07: Elms and first butterflies located by Rob Foster: these were hairstreaks high in canopy of ash / sycamore; looked like white-letter (dark with occasional sheen, rather than grey) but both elm and oak nearby. Moved into adjacent park, where MG found initially 3 white-letters at lower level canopy in full sun. Later two females seen crawling and flitting around just above head height. Total individuals recorded: 11. (From behaviour observed, wondered if emergence was later at this location) "We saw today (31-7-07) in Buxton along Bakewell Road and in the park which runs alongside it (SK065 735), bordering the Wye below the Wye Bridge Inn. The valley there is thick with elms, many of them 40 or 50ft high. Initially, the wlh we spotted were along the road, but too high in the canopy to be distinguished from purple hairstreaks. Later, however, in the park, we saw males spinning and females egg-laying close enough to see the w markings on their wings. Altogether we saw more than 10 wlh (we counted 11). This makes the status of SK07 "wlh in 10 km square" and since I was unable to find any viable elms in the tetrad, I expect this will be the highest status this square will achieve." - Rob Foster 29.06.07: I found elm in the the target km square, but only two spindly seedlings barely 6 ft tall SK050 779 300m in a copse by Pye Greave Farm (I wonder if these should count since they are probably incapable of supporting WLH) I found no elm in the remains of the tetrad. I was not able to search all of it, but much of it is moorland and devoid of trees and most of the trees in the lower fields and stream beds are scrutinisable with binoculars from a footpath running past Allstone Lee Farm. They seem to be mainly ash, alder and hawthorn. Elms seem absent, which is especially curious since wych elms line the stream beds only a little downstream. I identified no WLH caterpillars pupae or butterflies (30-6-07). The weather was cold, mostly overcast and generally unfavourable for butterfly sightings.. At 10km level, the closest elms to the 1km square are in the bed of the Pyegreave Brook and by Rye Flatt Cottage SK 045 783 unfortunately some 300 metres outside the tetrad. These are wych elms about 20-25 ft high, mostly overshadowed by taller trees. Some can be accessed from a field behind. This side is a south-facing and in a sheltered position which looks quite promising. Binoculars showed what might have been a pupa on one high branch.

unconfirmed 1 14.07.07 [elm] 10.03.09 eggs SJ145330 at 1km level, SJ157334 at 2km level Rural Rob Foster, Liz Goodyear & Andrew Middleton 10.03.09: It wasn't planned to visit SK13 on this visit but due to delays on the M6, diverted our journey home via the A50 which passed directly through the target! First found the elm found by Rob but felt not sufficient to sample so looked at the 2km level, where a very small tree produced five hatched eggs including four in one joint. Returned to look at 1km level and just inside target by just metres found a single tree beside the old road, where a hatched egg was found. 14.07.07: Had a brief look at the target km square SK14 33. Flacketts Lane Farm falls more or less in the middle. Flacketts Lane itself runs more or less north-south across the square, another rural lane runs diagonally across the NE corner and the A50 runs E-W across the bottom ot the square. Most of my observations were made from the lanes. Elm occurs commonly in the hedgerows of the area, noteably, thickly in those outside Flacketts Lane Farm. Perversely, other than that, within the square, elm occurs as only as occasional bushes within the hedgerows, whereas just outside the square it often constitutes the complete hedge. Hedges like this can be found along the lane which runs NW- SE notably close to Oaks Green (in the tetrad) and Smithy Holding (not in the tetrad, but in the 10km square). The elm is mostly large-leaved and presumably wych elm, although there is also elm with smaller leaves in the hedgerows near Smithy Holding. The hedgerows are evidently regularly trimmed. No small elms or trees of any sort have been allowed to develop along their lengths (although there are tall ash trees in the fields behind them that might be attractive to WLH). Nevertheless, I found some small elm trees in the km square, for instance in the under-story of Merefield Gorse, a wood in the NW corner. In particular, I found a small elm (about 20 ft) oposite Flackett Lane Farm. It is over topped by a tall oak. In the late evening sunshine, as I was about to leave, I noticed that there were insects that looked like moths or butterflies zig-zagging around the top of this tree. However I was unable to convince myself that they were WLH; they seemed too small.

11.07.07: Went out with Martin Greenland today looking at elms which had been found so far in SK18. Weather very windy and overcast, but nevertheless, in a brief sunny spell, saw WLH butterflies (3+) on large elm by Castleton Brook SK148 828 (190 m) see www.whiteletter.multiply.com in photo album SK14 82 Castleton Brook. Martin also found egg case on same tree. Searched trees in target km square and tetrad, but no luck. So the status of the square remains unchanged ie "LWT found in 10km square" as it was following Martin's finding of pupa near Hope in June.
18.05.07: My first thoughts were that the site would be too exposed for elm, but I noticed on www.naturenet.net/derbys.html that the NT Winnats and Mam Tor reserve of the High Peak Estate has wych elm noted as present on the reserve. Indeed I have just briefly visited the area and can see a few imature elms at the lower edge of the car park and a 2 stunted mature ones on the path from the car park up towards Mam Tor. This has been confirmed by the National Trust "Elms are present as you say in/near the car park, also there are a few above the car park, other side of the road onto Rushup edge, and at the foot of Mam Tor ( bottom turning area of the old road ) around and above the entrance to Odin Mine, and I think there may be the odd one near to Mam Farm. Odin Mine--- be a bit careful around there, there are some steep drops into the gorge and the odd old mineshaft, good idea to let a friend know that you are back safe."
Elm visited by Martin Greenland "Plenty of wych elm (a few with seed) in woodland around Mam Tor car park. No signs found - elm would be suitable in a less exposed situation."

1 July 2007 and 17.03.09 SK2108 at 1km level, SK212092 egg at 2km level Rural Mike Smith, Liz Goodyear & Andrew Middleton 17.03.09: A lot of records are known at 10km level, so it was important to get close to the target but based on reports there was no elm. Driving from the Tamworth direction, we saw a giant elm by the Wiggington PH which we intended to return to. Saw all the hammered (neat) hedges at 1km level and continued driving through the 2km level before turning back. To our amazement beside the road was very large elm and to our surprise we found an egg on the sampled elm. There was a lot of elm available for eggs! July 2007: There are six or 8 sets of suckering elm growth at SK211089, a short track off Portway Lane which leads to a railway bridge. The suckers are in the hedgerow either side of an old dead tree - presumably the original elm. Unfortunately the hedge is overgrown and hawthorns some 25 ft high dominate the hedgeline and the elms are no more than 7 ft high. I doubt they will be able to grow to flowering height. No butterflies seen. At SK219087 the field hedge consists almost exclusively of elm over a length of some 40 metres but it has been flail trimmed, probably 18 months or so ago, and none is more that about 8 ft high - no sign of flowers or butterflies and no sign of the holes and 'ladders' in the leaves that indicate the larvae have been chomping away. This is a characteristic feature in my local WLH patch where I can report three WLH seen yesterday (Staffordshire)

24.07.08: Watched both 1 and 2km elm for some time in good sunny conditions, mid afternoon - no activity but should be present?
04.11.07: Drove around 2km level, mostly planted trees but found some elm on Bretton Way and particular on Flaxland, opposite back entrance to Sainsburys. Road goes through a remnant scrappy bit of wood where elm was still present. Drove to 1km with little optimism. Most of the target was modern housing with modern planted trees, and an industrial estate. Driving through industrial estate, looked to one side and to my amazement saw three planted elm trees only to realise they were right opposite Peterborough Prison by the visitor reception!

09.12.09: One final attempt at finding eggs failed.
01.07.09: No activity at 10km level visited by MG in end June and LG/AM on 1.7.09.
03.11.08: Returned to sample elm and found that Holbeach Park elm had been felled, just some remnant sucker growth by walk. However, elm found at TF397259 extends along hedge into adjacent 10km square giving a good length of healthy elm, elm sampled but no eggs.
16.07.07: Found elm at 2km level but levels of elm in landscape so low, continued driving through 10km square. Found a single elm tree in a Holbeach park and watched in good sunshine for 20mins no sightings. Continued driving and found some good wood edge elm just inside 10km square and watched for 30mins. Through binoculars a very quick flight was observed that looked like wlh but no further sightings. Can not be confirmed until further sighting made - this fenland area has no wlh records so important that another sighting is made and as a result of negative egg searches presumed not to have been white-letter!

06.05.07: Section of clipped hedge as field boundary. Unsuitable. Appeared to be no further public access to TF9426 (1km level). At 2km level, no eggs/larvae found on sample of accessible branches but well worth returning during flight period (TF953273). Visited 05.07.07 and watched several areas of elm along Westwood Lane, no activity.  Drove along byway towards Highfield Farm and found nice healthy hedgerow, confirmed by farmer as best in area. Permission given to park in small field entrance by elm. Farmer may look - very interested!
18.07.07: Returned late afternoon and drove up through 10km square. Just outside 2km, along byway found several large elms alongside woodedge. Watched edge for some time but late afternoon and most elm in shade or too exposed. Hairstreaks seen over ash but not confirmed whether purple or white-letter. Watched Highfield Lane elm in late sunshine, no activity.

Salt marsh/estuary edge/rural Andrew Middleton and Liz Goodyear First impression as we drove into 10km square was that there was little elm. After some driving we found a small wood with elm and sampled some twigs. After some searching an egg was found on a growth joint on an upright twig. Drove to 1km level, which is part salt marsh, and found a belt of wind swept elm, no eggs were found. However, at 2km level we found some more sheltered elm beside the Cresswell River, on the road to Lawrenny Quay and 1 egg on a growth joint was found further down a stem which was laying level. We felt there was moderate levels of elm in the area and we believe this to be a new 10km square.

Some was located close to the estuary alongside the Pembrokeshire Coastal path and we waited! At 1.45 the sun came out and a white-letter was seen to fly from a probable roost area and then two were seen to fly up into the air. We did not visit the target and continued to look for white-letter in adjacent 10km squares.
October 2008: Apart from northern edge most of 10km level square quite high altitude and predominently moorland. Actual target moorland but at 2km level, much runs through Cwm Gwaun, a deep valley. Elm was seen on valley side by road, but no eggs found. Further down road just outside target at SN025340 some nice elm was seen by Dyffyn Arms Pub in Pontfaen which would had good vision (not searched for eggs). Drove through 10km square towards Newport where there are known to be historic records, then drove along A487 and a medium tree was seen just west of Newport and elm sampled for eggs but nothing found. Overall levels of elm in 10km is low.

21.07.09: Not visited properly.
October 2008: Target 1 or 2km level, void of suitable habitat! An undulating and relatively well wooden 10km square with much over 200m+, predominently beech and very little elm seen throughout the 10km square. More elm seen along A485 in the south of 10km square near Alltwalis, but almost immediately we left 10km to the NW, elm was seen in Llandysul. No eggs found on sampled trees.

20.07.09: Watched elms in various locations but no adults seen, more elm found in Lampeter and a hairstreak was seen flying across through binoculars but oak was closeby.
October 2008: Elm could be seen from hillside in river valley at 1 and 2km level but no access although on the road bend near chapel just as the B4337 enters the target there was some elm (SN525490)that could be worth a flight period visit. The accessible part of the 1km level target was higher up the hillside and not suitable habitat. Around the village of Llanwnnen, lots of elm could be found and some was sampled but no eggs found.

A large elm was found in the target but it was far too high was anyone to find eggs but is worthy of a flight period visit this summer.
14.10.08: Very little elm was found throughout 10km square, however there is an old record from 1973 'Dinas Rhandirmwyn/Towy Bridge.' We went to the bridge and there is a wych elm on the river bank right by the bridge and opposite a public house. We can only assume that someone was visiting the area and saw a white-letter. Therefore we strongly advise a flight period visit again. Elm sampled but no eggs found. We took a footpath along the river bank going south and there was no elm. Further down the valley in the adjacent 10km square elm was much more abundant and we again sampled for eggs but nothing found this time.

More elm found at Pont Melin Fach beside river and only a Clouded Magpie moth caterpillar found on elm.
20.07.09: Looked for eggs and walked to first set of falls, more elm found but despite some good sunshine, no adults seen. Target high altitude (mostly conifer plantation/mountain).
There are records for this 10km square from 1977, 1979 & 1980 from Ystradfette. This is a popular tourist attraction (caves) and we found elm beside the river and above the rock face at SN928123. Some elm was sampled but no eggs found. This target warrants a flight period visit although we couldn't predict when the butterfly would be flying!

30.10.09: Drove through Elan Valley but no new elm found.
15.10.08: A second visit included driving around narrow roads to south of target around Llanwrthwl and along river valley. There are two records from 1978 and 1980 from Llanwrthwl. Elm was seen along A470 in adjacent 10km square but fizzled out once we drove into SN96! The A470 appears to have been widened and straightened and perhaps elm is no longer present? We also looked at river in Rhayader but there was no elm beside the river.
05.08.08: no elm seen at 2km level. Only the area roadside around Rhayader searched and wych elm sprinkled at low level but present. Not far from town centre along A470, 2 wych elms, including a large tree roadside SN973678, no eggs found and weather poor - elm at 10km level and old previous record.

Rural Andrew Middleton and Liz Goodyear 17.02.09: Searched 10km for more elm, and several good areas found and elm sampled, all but one negative but should be surveyed during the flight period for adults. Final elm found (2 x 30/40 yr old trees) by roadside just beyond Brockhampton Park produced an unhatched but white egg just below base of terminal bud. This was a hard 10km square!
15.10.08: A return visit found elm at SO629544 just off A44, elm sampled but no eggs found. Elm seen along A44 on edge of Brockhampton Park where there are records from 1984.
31.07.08: Very small amount of broken hedgerow elm on edge of 1km square in Collington on roadside; otherwise no elm found at 1 or 2km in thorough search. Elm low in landscape searched along A44, although c5 small large leaved/wych elms along A44 in Bredenbury; no eggs found in brief search, although WLH worth searching for as no previous records (Herefordshire)

Suburban Gavin Woodman, Liz Goodyear & Andrew Middleton 17.02.09: Drove around 1km square and found a planted elm in the grounds of a secondary school. Permission was given for us to search but the density of buds made searching very difficult and no eggs found. Further exploration found a bank of elm at SO851538 and finally a small stream side wych elm, which when sampled produced 1 egg on leaf scar of 2008 growth (unusual) and 2 hatched eggs on upper edges of growth joint. The school grounds elm should be surveyed in the flight period (a second tree was seen on the other side of the site).
April 2008: Stopped in a lay-by on A449 at SO856580 several patches of small sucker growth some flowers on these, some with small disc shape of seeds already starting to develop, 2 larger dead trees, several larger trees with well developed flowers maybe source of sucker growth. Checked old leaves they were 2-2.5 inches with characteristic offset at base of leaf. Bark and buds shape different to what I have seen before not 100% sure they are elm. Most of what I had seen was sucker growth and not part of the hedge as I previously stated. Several very small caterpillars found on developing seeds but were not WLH.
On Sunday 24th February when I was returning from a works party I asked my friend that was driving to make a detour so that we would pass through the 10km target square SO85 on our way back to the M5, we travelled along the A449 through the 10km square to get to junction 6. All observations were made from the moving car; I was not able to stop to confirm identity. 10km Level: Bank of small and medium size Elm trees at SO849594, Medium size Elm tree by the bridge at SO853590. Several sections of Elm hedge by the A449 at SO8758 and SO8857. The tree by the bridge look like it was Wych Elm. The other trees and hedge rows had the right structure for elms but they are not the types that I normally see on my own patch, new looking uncut hedgerows so could be any variety. Because I was not able to have a closer look and confirm identification with old leaves, buds, flower etc I am reluctant to submit the information, will hopefully be going to this same works party next month so will try and confirm ID.

Saw it on southern edge of Mere Copse. Also saw 3 Purple Hairstreak on adjoining oak. Binoculars confirmed above as accurate - Richard Southwell.
02.03.09: Drove through 1km enroute to SJ70 and found a small healthy wood/field edge elm, sampled for eggs and 2 hatched eggs found, 1 on 1 yr growth joint, 1 on 2nd yr growth joint.
24.07.08: Was out looking for new sites for White Admiral and SWF today - failed - but went to an area I last covered for the Millennium Atlas and found WLH - but only after walking past a broad leafed elm in a tired state and thinking that's an elm - took trouble to double back, pulled branch and dislodged two WLH. GR SO801824 so it just creeps into decad that covers SO 8189. I then went to monad but no luck - the elms that are there are well trimmed in the hedge and the only decent sized one has just got DED.
May 2007: Monad fully covered - elm in 4 areas - best by roadside - no positive ID for butterfly so far (4th June 2007 - Richard Southwell). To be visited by West Midlands Branch volunteer Ed Andrews. 10.07.07: still no sightings

I have recorded a part of the area in recent years. This area is old large-scale industry, so is primarliy brownfield site these days. Typical of the Black Country the area is 'attractively' known as THE LUNT. Due to your project I have now covered the area east of the canal for the first time ever. Wow - it is fantastic so thanks for that. Regarding the WLH project unfortunately absolutely useless - there is no elm whatsoever. Trees etc present are - Silver Birch, Alder, Lime, Field Maple, Common Willow, Rowan and lots of Hawthorn. (Unlikely to be present in the 2km but not an area to leave cars parked!) On the greenbelt edge there are elm hedges. Loads of regenerating elm in decad at Wrens Nest - the council officer Anna Gorski is allocating at student and herself to check it out.

No elm found in NE section but drove west across north side of 10km and eventually found some roadside/wood edge elm. The wood edge was sampled and a hatched egg was found on old growth joint. Believed to be a new 10km square
No elm found in thorough search of 1 and 2km level, well-wooded area but beech, hazel, heath. A little elm at SP023736, otherwise not intensively searched at 10km; no previous records so worth searching for elm - general levels appeared low though.

02.03.09: Drove through 10km and looked hard for elm, nothing seen at first and visited Elmdon Park south of Birmingham Airport and close to the Landrover Plant. Several elms seen including a nice tree by housing, sampled and 2 eggs found beneath bud and beneath growth joint. We then drove to the target, passing several healthy roadside elms along the A45 including planted elms. Drove as many roads as possible at 2km level and no elm was found by just 100m outside the 1km at 10km level, some healthy elms were found on the edge of playing fields. These were sampled and 1 hatched (on old growth joint) and 1 egg on side of twig found. A very pleasing find so close to the centre of Birmingham

No elm visible but continued into Bledington where roadside elm was found and sampled. 1 egg found! More quality elm found at SP283264 which would be worth watching for adults.
However, virtually no other elm seen at 10km level (28.02.08). Drove through 1 and 2km and only elm noted on wood edge near church - no eggs found. Possibly more in background so worth rechecking. Just outside 2km near to main road (A436) a few trees seen in a small wood.

17.11.08: Drove through target 10km square enroute to National AGM! Elm almost immediately seen on entering 10km sq but then looked very unpromising with heavily flailed neat hedges of elm! Continued into target 2km, where habitat continued to look unpromising but due to a 'clerical' error got the wrong 1km square so thought we hit the jackpot on entering 'target.' Looked like a change of farmer, and roadside hedges were unkempt and lined with elm of varying quantity. However, we had checked the 'correct' target 1km (should have been SP4458 not SP4459) but access restricted although elm was seen on wood edge and the brief section of road that touched the target. Public footpath access reasonable so we should be able to find Wlh at 1km level but for time being restricting to 2km level elm only.

20.08.08: Sampled some elm for eggs but nothing found. However, just as about to leave 2km square, we saw a large planted hybrid elm in the backgarden of a house. This will make the 2km level much easier to complete in 2009!

20.08.08: Sampled a few bits of elm and a hatched egg was found. This was a great success as there is a lot of roadside elm some now suffering from DED, but it would have been hard to decide which bit to watch for adults and avoid cars!
14.04.08: Check of target SP 5423 confirmed last year's finding that there is only hedgerow elm in the square, most of it flailed. Roadside elm trees on north side of B4030 in SP5523 (fairly young, many diseased) were breaking into leaf but one fairly substantial tree on south side was found in flower at SP 551231.
22.09.07: Agricultural land with a motorway (M40) running through it. Initial drive-through - no trees were found in the target square but there is some hedgerow elm. However, this is probably unsuitable as flailing is prevalent in the area. Elsewhere in the tetrad (certainly in SP 5523) there are some larger elms and several dead ones were also noted.

01.04.08, looked for elm at 10km level first and drove towards Little Downham, stopped at some roadside elm (first elm found) and sampled elm where several hatched eggs were found on one stem. Sampled 2km elm but no eggs found
29.06.07: 1 tried my Littleport square - found fair bit of Elm at 2km but all quite short re-growth and lots of new disease. Didn't record any WLH - very windy very frustrating.
01.07.07: Bill and I visited TL5589 and drove the lanes. The target 1km looks like fenland without any suitable hedges, or many hedges at all. In the SW corner of the tetrad there are some nice hedgerow elms that should hold wlh – just a bit exposed and windy that day, and didn’t spend much time looking
Elm found in adjacent 2km square (TL5587)

Surprised to find a large mature tree and a nearby smaller 'bent' tree. The smaller tree was searched for eggs and a hatched white-letter egg found. Additional tree found just outside 1km in hedgerow next to ditch.

No adults seen ... ... but found a hatched eggshell on the wych elm (pictured) at TL696913 !! (Know I've looked at the tree before; the egg wasn't in a conventional place - perhaps I overlooked it before) - Martin Greenland
28.10.08: Success at last.... drove around the NW corner of the 10km and found some patches of elm and then along B1160 just outside Wissington Sugar beet factory, elm was seen on both sides of the road. Sampling was undertaken and 2 eggs found one thought to be a damaged egg from 2008. Further visits still needed at 1km level to confirm whether white-letter really arn't present?
24.07.08: Still no sightings....
24.06.08: Still no sightings - Martin Greenland
01.04.08: Returned again to sample elm for eggs but nothing found!
18.07.07: This was the third visit during flight period but only time when we had any sunshine. Found more elm alongside footpath and first watched this for 15minutes in solid sunshine. No activity. Returned to original elm and again watched for 15 minutes in good sunshine after more rain and a change of wind direction which made conditions more favourable! No activity except for Vapourer and Holly Blue. We need to revisit in 2008 in better and earlier flight period conditons. Were surprised not to observe activity considering extent of elm!
09.05.07: Despite 2km square being on the edge of fenland, a green lane leading from the 'cut off' channel was elm lined, and several hedgelines were predominently elm, mostly non-flowering but two trees with flowers but out of reach. Quite a surprise considering location!

Good length of elm with some low buds found by bridge and footpath. 20 minute search (small sample of buds) found 10+ hatched Brick eggs.

Further visit to 1km on 9th May 2007, found elm in TL7589 and more elm that had been retained when a conifer plantation had been recently felled 320m out of 1km but at 2km level. 1km still requires more surveying as elm could still be amongst plantation growth!

As the 'new' road ended, roadside elm seen immediately but best elm was just into next 2km starting at TL870480 by layby!  More thorough search of local footpaths needed. Flowering roadside elm A1092/Kentwell Park/Melford Park. 2nd visit, took footpath across 1km and found elm in hedgerows at two locations. Leaves searched but little in reach

Park (Council) Rob Parker, Liz Goodyear & Andrew Middleton 30.06.08: This morning (30 Jun) started warm, bright and clear, so I got to the bus stop elm (TL865633at 0905, and almost immediately saw a possible in the crown. By 0910, I had watched a pair of w-album spiralling up on 3 occasions. No close-up views, but I'm 100% sure of this hit in the 2km square (TL865633). I cycled straight on to the 1km square, and checked Nowton Park North, Hardwick Lane (scruffy elms), and then some better elm at 2km (TL877622). Sadly, in all 3 cases, some of the elm was suffering from DED and this years fresh-grown leaves were already dead. No more WLH were seen. SUCCESS! but only at the 2km level - Rob Parker
7.7.07: I took a look at TL8662 in the bright intervals this morning, and found nothing on the Nowton Park elms (apart from some interesting galls), and nothing at the other site I have been checking at the 2km level. However, at Hall Farm TL 865672, a copse I have found them in several times in the last 5 years, I saw 2 (or3) WLH - so that is success (of a sort) at the 10km level. One small elm, in flower (nearly) somewhat over shadowed by taller trees. More elm known to be in next 1km square south (still within park). No eggs found. Additional notes added 19.03.07 - I re-visited Nowton Park yesterday, I found a better elm in the same 1km square - right next to where I had parked. It was in blossom (just) but several other, older elms which I have been watching for a few years for wlh - are without, as yet. 01.04.08: Drove through 2km square and found a several clusters of elm including large quantity by roadside sampled for eggs but nothing found. Must be revisited in season! [LG/AM]

Walked along footpath and found Lexden Spring LNR. At bottom of reserve behind A133, a bank of inaccessible elm was found which included two tall trees. At the top of the hill was a row of elm. Also seen 3 Scarce Chasers and Pignut found (food plant of Chimney Sweeper moth)

18.07.07: Visited site for the first time during flight period and first visited 10km level elm at Hargham Heath where adults seen in 2006. Activity confirmed. Watched roadside elm by nursery for 10minutes but no activity. Condition of elm now quite poor. Watched A11 elm for 15minutes in ideal conditions but no activity. Needs revisiting in 2008.
23.01.07: Drove around TM0292, no public footpaths no elm visible - roadside elm 170 metre north next to Rose Nursery (B1077). More elm alongside A11 new bypass in line with Rose Nursery - should be sufficient. Elm in landscape. 3 adults seen in adjacent 2km (07.07.06) square

28.10.08: Visit Methersgate with intention of looking at 2km elm for eggs, however it was necessary to walk through 1km and we decided to sample the 1km isolated wood edge elm (there may be more elm in the wood?). To our surprise 2 eggs were found both beneath buds, one end tip of side shoot.
Martlesham Heath visited by Steve Goddard and one adult seen nectaring on bramble
Re-visited 03.07.07, arrived in torrential thunderstorm and waited for sun to shine, watched 1km elm but no activity. Looked at 2km elm and found more in landscape (private site - permission required to survey). Elm looks promisisng but no activity seen in late afternoon sunshine. Downgrading square to 2km level as elm first identified is probably too small to support wlh. 29.05.07: It was necessary to walk into target 1km from adjacent 10km. We walked along private driveway (public footpath)to Methersgate Hall through elm lined hedgerow. As we reached target, the hedge changed to an avenue of planted trees and all elm disappeared. Elm found on bend of track but visibility poor with elm on private land. A further small tree was found beside track and on a footpath a small cluster of isolated elm was found. At 2km level good level of elm found but a lot of dead elm also visible in landscape. The soil was very sandy (edge of Sutton Heath and close to Deben Estuary)

Also one perched. Excellent result considering quantity of elm! 05.05.07: Despite a high level of visible roadside elm at 10km level, actual 2km was very poor and little seen. Drove through target 1km and found two small areas of elm, which hopefully should be sufficient. Several footpaths could still be walked but landscape did not look encouraging nor do aerial photos!

Moved onto 1km elm and watched both areas in sub optimum conditions although some sunny breaks, no activity and no eggs found.

ST505295 Rural Chris Iles 29.06.08: Good news, WLH seen yesterday in target square ST5029 - one seen fluttering between two ash trees when I arrived and again about 20 minutes later when the sun finally made a reappearance.
19.09.07: Somerset Wildlife Trust's newsletter mentions that White-letter Hairstreak was recorded at Green Down in ST52 this summer - 10km level at least (part of the reserve is at 2km level for our target square). I've attached a photo of habitat in the target square ST5029. I must return and check for eggs once the leaves have come off the trees. Should be easy to check as you can get up behind the trees and look into the canopy. There are larger elms on the other side of the railway bridge but they are very difficult to photograph!
7.7.07:Possible WLH in target square ST5029 7.7.07, seen briefly flying between elm and ash. Holly Blue-sized but appeared silvery in flight (definitely not Holly Blue, and appeared too small for Purple Hairstreak and no oaks were in the vicinity).
17.6.07: Plenty of hedgerow elm both in leaf and dead at ST505295 where the railway crosses over a country lane - photo to follow at a later date I hope. No sign of the butterfly though despite 30 minutes' scanning of the tops of the elm trees and a large nearby ash tree; only having 5 minutes of sunshine did not help. Noted at least one small hedgerow elm elsewhere within the 1km square.

Chris Iles, Liz Goodyear & Andrew Middleton 28.10.09: Drove into 10km from a different direction along A371 and avoiding hills. |Almost immediately on western edge of Shepton Mallet found a elm rich wooded gorge. Some elm had been felled as part of road works but in wood, an elm was sampled and an egg was found immediately at 10km level.
18.07.09: Nothing to report I am afraid - weather has been very frustrating in the early mornings - Chris Iles
14.07.09: Watched large 2km elms and nearby 10km elms in very breezy conditions with only short bursts of sun, nothing seen
07.04.09: Driving back from the West Country decided to detour via ST64, roadside elm was seen at Doulting and more large trees were seen beside the A361. They were so large, it was hard to believe they were actually elm, but being in seed helped! The A361 clips the bottom of the 2km target and at ST678441 two large trees were seen beside the road with a bit more scrappy elm in the entrance of a house. No eggs were found but much is totally out of reach. The site is very exposed and it will be interesting to see whether they support white-letter?
28.06.08: Tried at 2km level in ST64 today but no joy, probably as the weather was overcast and there were no butterflies of any kind to be seen. There is feeding damage to the elms though, so well worth another look in a few days.
10.6.08: I have looked at a couple of the target squares again in the last couple of weeks. ST6745 appears to have no elm but I have found elm in the tetrad (ST6645) - a couple of 20m+ trees - looked for larvae of which there was no sign but there were a few leaves with WLH-like feeding holes in them. Looking for the adults there will be difficult but I will try.
Summer 2007: No elm found in 1km square in 2 visits. Two woodlands in the 1km square - the larger is youngish beech plantation, the smaller coniferous plantation. Plenty of hedgerows bordering green lanes but there appears to be no elm there (not impossible I have missed some). None found at 2km level either. Nearest elm I have found to date is at ST646488, at 10km level.

I have been looking for elm nearby, in ST65, ST75 and ST76, in all of which it is common if patchily distributed. I will look for the butterfly there as well. It will be interesting to see results for ST65 and ST75 particularly which have only one record apiece in the last 20 years.

Rural Andrew Middleton and Liz Goodyear 04.04.09: After several visits and the knowledge that there is a recent record, returned again and started searching at 10km level from the SE corner. However, still no elm of note could be found until at last along the B3143 close to Pulham, a small wood beside the road held several elms including field edge examples. An old hatched egg was found on main stem under side shoot on 2 yr old growth joint. This had been one of our hardest squares! Dec 08: Second visit driving around 10km, still couldn't find any elm, despite knowledge that there are modern wlh records at 10km
July 08: Drove around 1 and 2km and then to NE at 10km level. No elm found at 1 or 2km level, although hedges contained elms, these had all been flailed. Just one small tree by telephone pole seen. Virtually no elm was seen throughout visit, although a good length was found but most had recently succumbed to DED (ST753062). Further visit required

Rural Liz Goodyear and Andrew Middleton, Maurice Avent and Hugo Brooke and Bruce Maxfield 22.07.08: Invited by Maurice Avent to visit Colerne Park and watched wych elm for 2 hours before sun came out. at 12.34 first wlh was seen and more sightings were observed including one perched. Later saw 3 nectaring wlh in adjacent 2km square!
17.07.08 Maurice Avent had unconfirmed sighting in 2007 of 2 adults clashing at 1km level
15.07.08: watched 2km elm in relatively good conditions but hard to view, so left target and drove through 10km a different route, just as about to leave 10km square elm seen by railway depot, and AM with binoculars looking over fencing saw a wlh fly out
03.07.08: Limited access to 1km but drove around 2km and found wood edge by roadside trees which contained several elms, needs visiting in favourable weather conditions?
July 2007: Bruce Maxfield recorded adults at 10km level but not been able to visit target squares yet - 19.7.07. Elm visible through 10km along M4 corridor further north than target [Liz Goodyear - 13.08.07]
ST89 ST8591 50 flowering wych elm within plantation - no images 1 24.03.08 ST854917 Rural Matthew Oates 24.03.08: Charltondown Covert. Mix of ash, sycamore, beech, small conifer plantations and at least 50 Wych Elm of flowering age, plus some scrub English Elm. No elms in rest of the 1km square. Single egg found on flowering wych elm, at ST 854917. Very little of the elm is within ground reach. The wood should support quite a good population, especially in southern half. Needs surveying during flight season. Note that WLH has a reasonable presence in the general area.
2007: There’s a good chance of there being some wych elm there as it likes the geology. The butterfly is widespread in the district, though colonies are short lived. But I’m more likely to work the eggs, particularly this year. There is a large colony 1 mile SW at the W end of Silk Wood (ST834893) based on about 2 ha of a Himalayan elm called Ulmus villosa which the FC planted there as a DED experiment, and which is less susceptible to DED. However, numbers have been horribly low this year due to foul and abusive weather. This must be one of the most difficult White-letter Hairstreak seasons of our era….

08.06.09: Most promising 1km elm (including wych) was on roadside alongside Whitehill Industrial Park SU059825. More 2km ?hybrid elm with wych characteristics (also English) along left hand footpath after M4 farm track underpass SU047837 - unable to find any eggs, though. Plenty of 10km elm in vicinity of Wootton Bassett Jubilee Lake car park SU071837: small wych elms in woodland approaching lake; 3 large smooth-leaved on roadside alongside adjacent nursery school; plenty of scrappy English elm across road. Definitely worth a look.
07.04.09: Returned to look for elm at 10km level south of the target and away from known records although it was late in the day and time was short. Little elm was noted and some found was extremely exposed and out of reach. No eggs were found on elm searched.
29.07.08: Found some good elm on M4 embankments and watched from road below. Very windy so difficult to view most sheltered parts but no activity observed between rain showers! LG/AM
24.07.07: I spent an hour at the SU0582 site this afternoon. I walked slowly along the road but did not see any WLHs and could not find any eggs on branches low enough to reach. The sun was patchy and it was a bit windy so conditions were not quite ideal. I would not be surprised if the butterfly is present, there is so much elm there. The southern part of the square is difficult to reach because of the railways but I scanned across the area and from what I could see I think the best elm is along the road - John Grearson

Rural Martin Greenland, Arthur Bryant, Liz Goodyear & Andrew Middleton 14.07.08: Arrived early as sunny - at 9.15 wlh was seen jittering between elm and adjacent trees.
23.06.08: Nothing seen in 1km - concur with Arthur Bryant's comments. But plenty of elm in the tetrad in SU1626; I'd be surprised if wlh was not present at Bodenham, even though I saw no signs in the middle of the day today (?too early in season). Requires another visit - Martin Greenland
July 2007: Had a chance to visit SU1627 last week in reasonable conditions to look for WLH. There is a hedge along the track that goes through most of this square and it contains a high percentage of elm. Unfortunately it appears to be flailed regularly, both top and sides, so little chance of eggs surviving. Nothing seen in 50 minutes. Only 2 or 3 isolated bits of elm have managed to make any decent height. There is a long stretch of elm hedge in a field off the track but there was barbed wire wound round the gate so I took the hint. The adjacent square SU1628 also has hedges containing elm and they do not appear to have been cut recently and these looked much more promising but nothing seen - Arthur Bryant

Well-worth returning for adults. No eggs found at 2km level and elm in adjacent 2km square too high for searching!
03.07.08: Access to 1km is limited and habitat looks unsuitable, elm could be seen along A4 at 2km and 10km level. Elm at 2km on a good day should hold wlh!

Target area rural but remaining 10km mixed urban, suburban and estuary Liz Goodyear, Andrew Middleton and Martin Greenland 26.01.09: Visited 2km for winter egg search only to find the best hedge had been flailed and most of the elm cut, just three minor trees remained. Sampled for eggs but none found. Decided to look for elm close to the River Itchen and drove into the Lakeside Country Park opposite Southampton Airport. Just beyond carpark near Fishery, saw a single elm tree by footpath, sampled for eggs and one egg was found.
23.06.08: Nothing seen 1140-1210hrs in sunny intervals with light breeze (or in very windy conditions at 1600hrs the previous day) - Martin Greenland
Martin Greenland: checked elm already identified by Liz and found no eggs - but mostly out of reach: both areas worth viewing in flight season. Liz Goodyear: Family committments gave me an opportunity to look around 10km between M3, Southampton and Eastleigh, which included target 1 and 2km squares. Drove around 2km twice, and eventually found two small areas of hedgerow elm down narrow lanes. No footpaths walked. General impression of target and adjacent area was well wooded but void of elm in landscape. Only occasional clusters of very diseased elm seen except for some roadside elm in Eastleigh at SU450191 (couldn't find on later visit!). East side of 10km not covered and Millennium update shows wlh has been recorded so there must be some potential areas somewhere. Better area of elm at 2km level could hold wlh if patiently watched at the right time based on experience at other similar sites but considering low level of elm in landscape might be difficult!

16.07.08: Drove around 2km and found to our amazement 4 planted elms by public footpath. Wych elm in understorey. Watched elm, but late in day and very windy. LG/AM
24.06.08: Sadly, since previous visit, Dutch Elm Disease has really taken hold among the elms along the edge of Spray Wood (SU420782) and the adjoining hedgerow (SU420788) so that all bar one or two trees are dying or already dead. No signs of wlh seen here or at the small-medium but healthy elms in the village (SU426785)
03.01.08: A few small/medium hedgerow elms on roadside at Brightwalton Green SU426785; more along SE edge of Spray Wood from SU420782 (more promising) and hedgerow at SU420788 (poor). No branches within reach.

Drove around Chidham in adjacent 2km square and found several areas of roadside, hedgerow elm. 1 adult seen flying out of elm and above road. 2km elm should maintain a colony and target needs a further visit.
22.01.08: Drove around the local roads in 1km and could see line of dead elm along a field edge but nothing healthy. Possible two other footpaths need to be visited but one runs alongside A27 where only modern planting visible!

Drove around key routes at 2km level and no elm seen. Walked several streets and footpaths at 1km level, and no elm found. Snapshot opinion of housing estate was that it was unlikely elm had been retained (unlike SU6554). Walked an 'old' footpath from outside 2km and a few elms found approx 200 metres from 1km but viewing will be difficult as close to housing and poor all round vision. Further visit to 2km square on 26.06.07 confirmed that elm is probably absent

22.01.08: Immediate impression of 10km was that elm would be hard to find! Walked into 1km from north and knew immediately the footpath would not yeald elm but carried on just in case - nothing. Returned to car and drove along A285, where short stretches of dead elm could be seen. Outside 2km some elm in a layby but much of it was dead. Later drove along A27 and some healthy budding elm was seen just east of Boxgrove. Much of 2km forms part of a private estate with limited access, just a few tracks with public access including Mill Lane that might have potential as ends by layby and dead elm?

Returned 17th at 8.15 in morning and after 30 minutes of watching a white-letter was seen in jittering around elm at 8.44 from roadside location. An excellent sighting considering level of elm in 10km square!
Various visits: General level of elm in 10km is extremely low
18.03.08: Returned to TQ22 and drove through 10km along A23 corridor and found a medium elm tree with adjacent smaller trees along the 'old road' just north of Bolney.
23.10.07: Drove into 10km from south along A281, some elm seen on entry into 10km but none seen at 2km or along adjacent roads. More thorough visit needed but general impression was that elm levels were very low?
30.10.07: Second visit proved that elm is virtually non-existent, walked into 1km square around the Leonardslee Gardens and no elm. No elm roadside apart from the short length on the A281. Local knowledge of elm needed although only one tree listed in entire 10km square by Sussex Biodiversity Records Centre!
TQ26 TQ2361 Good variety of Elm here. Some Common (English) Elm, White Elm, Wych Elm and another form which may be a hybrid? The latter are large and healthy (7 trees, some of which I cannot get my arms around at breast height). The Common Elm is regenerating sucker growth. Some of it now quite tall and flowering age but much succumbed last summer. I am not certain if this was DED or scorching as some has made a recovery! The White Elm are quite large and healthy- again, cannot get arms around a couple. These are also tall trees and there are several of them. 4 4 05.05.07 & 07.05.07 [l]

Quite a variation in size - one has started pupating, whilst one is about half this size. Couldn't put them back on tree as so windy, so trying to feed them up at home. It was very windy today (8th) and I expect to find more. Interestingly, with all this Elm to choose from, they have read the textbooks and used Wych Elm.

Rural Liz Goodyear and Andrew Middleton 13.07.08: Watched 10km elm and at 11.55 single wlh seen around ash, target not visited
26.06.08: no sightings but windy, continued to look for more elm at 10km as there are records
17.06.08: First flight period visit produced no sightings, but early in season, and 2km level elm in exposed location - needs to be viewed in afternoon.
General level of elm in 10km is low
12.02.07: Walked through 1km and adjacent 2km level. At 1km most elm diseased/dead, little good elm in landscape apart from 2 medium sized trees in bud and some hedgerow elm found closeby at 2km level.
30.10.07: Returning late afternoon, drove alone main routes through 2km square and in half light elm was visible roadside.

Rural, chalk downland at an altitude of over 150m Andrew Middleton & Liz Goodyear 12.02.08: Drove into 10km from west and immediately saw a large healthy elm in Wyevale GC carpark! Actual target is chalk downland close to Firle Beacon, landscape virtually treeless but on drive up to carpark several areas of elm passed just outside target 2km square. Beautiful views from target though!
18.03.08: Revisited and sampled 2km elm (little flower) for eggs, nothing found. Drove north of A27 and found some flowering elm and found three hatched eggs (1 on growth joint, 2 beneath leaf buds).

30.10.08: Drove around minor roads at 2km level and only some short lengths of predominently dead elm seen in hedgerows. Spent 2 1/2 hours walking footpaths and just one small tree seen in hedgerow just outside Ide Hill. At 10km level drove to Four Elms but no significant elms visible. Then drove along A25 through Brasted. A lot of quality roadside elm visible west of village. More elm seen along A25 before leaving 10km square to the west

12.02.08 and 18.03.08 TQ619255 and TQ679249- Rural Andrew Middleton & Liz Goodyear 18.11.09: Drove in a circuit around the adjacent 10km squares to TQ62 and found no suitable elm.
12.02.08:Drove into 10km square from west and quickly became apparent that elm would be hard to find! Sampled a track leading from east side of 2km across into 1km target and wood edge paths. No elm seen nor whilst driving around several roads at 10km level. Have asked Sussex BRC if they have any elm data for this particular 10km square.
18.03.08: Revisited and with information of 5 elm records. First target was some roadside elm but this was no longer present. Then walked to two listed targets. Elm found at one location but second location could not be found. Remaining locations were of English elm and old records so did not search out. Whilst driving along A265, stopped to check some previously noted trees which were confirmed as aspen but noted 2/3 small flowering trees in hedge on opposite side of road.
In view of such low levels of elm at 10km level, we feel that any elm in this 10km square is unlikely to support White-letter. We would like to be proved wrong!

Rural/Essex fenland A Middleton & L Goodyear 21.06.07: Returned for 2nd visit during flight period and had wlh at 10km level first. Started to watch the better quality elm which had flowered but was out of 1km, Andrew returned to the scrappy bit and had a flight around elm. Then 20mins later, one flew in and perched! An amazing success which was almost hard to believe!
05.03.07: Walked all paths in 1km - a lot of elm in landscape but all in very poor condition and no buds. Drove out of 2km and found row of healthy roadside elm in bud at TQ639835
TQ71 TQ7118 Elm found towards the south of the 10km including length of roadside elm (no photograph)

Rural A Middleton & L Goodyear Drove into 10km and appearance very similar to TQ62 so was not expecting to see any roadside elm at 1 or 2km level. Drove along roads but did not sample footpaths as getting late. As we predicted though we drove south away from the heathland habitat towards the chalk and immediately found several areas of roadside elm including one large roadside tree in bud beside a very narrow minor lane (no photo)
18.03.08: Revisted 10km square and revisted targets but all elm out of reach. Found some new elm (thanks to Sussex Biodiversity Records Centre) and sampled the elm, eggs and hatched eggs found (Old growth joints – 3 hatched, 1 unhatched. Old leaf scars – 1 hatched, 1 unhatched)

Rural TQ862525 (single tree) and TQ854511 (hedge) at 10km level Alan Cooper (adult sighting), Liz Goodyear and Andrew Middleton 24.07.08: Spent 58 Min's. watching the Elm you told me about, 1 flew off the Whitbeam and onto the Elm. very windy at c.6pm. Managed to stand in a derelict pasture and avoid the worst of the noise from the adjacent A20, M20 and high speed rail link. - Alan Cooper
26.06.08: Couldn't find Alan's 2km elm so looked at 10km level and found a large tree beside A20. Despite windy but sunny conditions no activity so looked for more shelted hedgerow/roadside elm but stll no activity
July 2007: Got to TQ8451 reversed into a field of broad beans with a "conservation margin" no Elm present to the north of this 1k. square, the main part of this tetrad is activally worked Chestnut coppice. Looked behind the recent housing in this (30 years old) estate no Elm, but it is present South at 2km level. WLH should be present around Leeds Castle, just NW in this 10k. tetrad, from memory lots of Elm suckers along the A20, perhaps there are surviving Elms in the extensive grounds of this Castle?

TQ9323 at 1km level, TQ9020 at 10km level Rural Alan Cooper 12.07.09: Woke up later than intended after a night shift, looking out the window and knowing the forecast. decided to watch Mark Webber win his first Grand Prix. Got to the Iden tetrad c.3-45pm.The weather had improved markedly apart from the wind which had increased dramatically, after looking at the area nearby where I knew WLH are present. I decided to look at the higher ground closer to the 1k tetrad ended up parking where I did a couple of years ago in the village walked towards the area on the OS map shown as the Elms a flailed hedgerow under telephone wires. coming back again looked at a few scrubby bits of flailed Elm under Ash and noticed Ivy growing up some trunks Then realised there was some passable Elm pushing over into a horse paddock. by luck a Comma and Red Admiral were sparring and disturbed everything in this sheltered corner including an "WLH nectaring on bramble" c.10 feet up on a mature hawthorn hedgerow. Elm noticed in the 1k square northwards. Did not expect to get a 1k record for here! only just by a few metres. got to the Ashford 2k tetrad too late on the drive home, always some healthy Elm here (suckers at least)
15.07.07: Went to a couple of semi mature mature Wych Elms at Appledore WLH found easily (10km level) for the Iden 10km. Tetrad(TQ9020) WLH must occur along the canal to TQ935245. Found WLH easily at Llydd cemetary and on couple of Elm growths across the Marshes. Can confirm Elm as present in TQ9223 as a regularily flailded hedge at TQ923239-924239, last flailed perhaps a couple of weeks before my visit. 2 more Elms in an also regularily flailed hedgrow just south in this 1k. tetrad.dead Elm suckers at TQ924239, WLH could exist sporadically in this tetrad. Elm suckers noted to the north in a different 1k. tetrad.

30.07.08: I had a good look in TR03 at the Elms at 2km level, more healthy Elm than had previously noted (TR010387) no WLH seen. Then tried some Elms at Brook just off of the Wye downs NNR. Again nothing seen.
05.07.08: Decided to get the WLH for TR03 where I knew I could find them. I visited the Royal Military Canal at Ruckinge (TQ027333) and found with binoculars a WLH on a moderate sized Wych Elm fairly easily. The English Elm at 2k. level is now rather sickly, did notice a few healthy bits nearby when I drove past in cloudy conditions a couple of weeks ago, did notice a reasonable parking place.
2007: Elm at 2k level in TR0139 - Elm being present around Kingsnorth. Found at TR009387 as an unmanaged "hedge" as the border of someone's garden, a pasture surrounds this regenerating growth.

This is the most westerly record and closest to Cornwall for close on 25 years and the first record from the Plymouth area for almost 10 years. Believed to be a new 10km square.
June 08: Not much elm seen at 10km level but drove into target and immediately found good quality roadside elm, view best from entrance to small holding. Keep quiet to avoid disturbing large dogs in yard by elm! Watched for some time in perfect but windy conditions, no activity, needs further monitoring

Moorland so High Altitude guidelines apply. Rural at 10km level Andrew Middleton and Liz Goodyear 05.04.09: With the knowledge that there were 2 old records from woodland in the NE corner close to Bovey Tracey (and close in the adjacent 10km square SX78) we walked into the river valley and looked for elm. At first we could not find any and wondered whether the records related to a wandering nectaring individual. However, we suddenly found several elms on the hillside with low branches and we found a hatched egg on a 1 year old growth joint. We still want to watch the large elms during the flight period!
December 2008: Winter survey work, proved that previously found elms too high to sample but searched copse elm found at SX769709 between slip road and A38 - no eggs found.
June 2008: Drove onto Dartmoor and as expected no elm! However, at 2km level on minor road we found a small quantity of wych elm by a farmyard (SX726774). Came down from Dartmoor and little elm seen despite known recent records at 10km level. Drove to the lowest point in 10km and found 2 giant elms. Watched in windy conditions and no activity observed, no eggs found. Needs further monitoring

June 08: Initially found elm at 10km level at several locations. Watched at SX742914 for sometime in good condition but apart from a small dark/small butterfly/moth flying across road nothing was seen. Continued to drive around 10km towards target, no elm seen and no elm at 1 or 2km visible. Drove out of 2km and found elm in adjacent 2km just inside 10km. Watched this elm as well for some time in good conditions but still no activity. No eggs found. Needs further monitoring

18.02.09: Roadside Smooth-leaved(?) elm in the 1km square SY165911 - but it is isolated and exposed at 186m.
Dec 08: More elm found close to Ottery St Mary and just on the outskirts of Honiton. All look very good targets which need revisiting, no eggs found.
June 08:Drove in 10km and it immediately became apparent elm was going to be hard to find! Target not visited and only a short section of 2km roads sampled. Some roadside elm in Sidbury but felt that in view of poor local distribution levels, better quality elm needed to be monitored first. Drove to west of 10km to Ottery St Mary and found 2 single trees on edge of village. Watched both elms in sunny but very windy conditions. No activity and no eggs found.

At least 9 planted elm trees were found on the edge of Dorchester but no eggs found. Worth visiting during the flight period.
12.07.09 Watched 2km elm early morning in good conditions as day warmed up and no adults seen, although a Vapourer moths were seen flying including one perched on underside of a leaf. John Davis also reports no sightings. Watched 10km elm near Winterbourne Abbas where only known record comes from but elm hard to view and conditions breezy so difficult to see a sheltered spot.
29.06.09: no adults observed.
Dec 08: Elm found at 2km level along A37 close to layby - sampled but no eggs found Elm is at 1km as well as at 2km. Some in the wood are about 15 m tall though I have noticed one prime one succumbing to disease this summer. The hedge along land westwards out of Frampton is almost 100% trimmed suckered elm. Tricky place to spend time looking for WLH though.

Rural John Davis, Liz Goodyear & Andrew Middleton 28.06.09: Watched 1km elm in early sun but no activity, so went to 10km elm found the previous day. Entrance to Hethwalton Wood, no activity but a bit further back along road, more elm and a single adult was seen flying around ash. 1 or 2km elm should still produce a sighting?
04.04.09: Visited 10km square and found elm quite hard to find, but at 2km level at least 4 tall trees were found in wood beside a road junction. Very tall and not possible to sample for eggs but should support wlh?
I did the elm search for the Lulworth Squ SY8885 - but did not manage to find the weather for an adult search. Most of the elm sadly moribund and dead - is present at the 1km and 2km scale and greater - the band of clay between the sands and gravels of the heathland firing ranges and the Frome valley alluvium seems to be where the elms are so potentially they should be found back up valley towards Wool. Will gear up for the new season - John Davis BC Lulworth

DED very evident and finding some good elm was quite hard, although eventually we found some nice roadside elm already showing signs of DED though. No activity on 26.06.09 but returned as sun broke through cloud on 27th at about 11am. Immediately 1 adult was seen flying around ash and then a second individual seen on another ash tree. A very satisfactory result although it's still possible that adults could be seen at target level. 09.06.09: Quite a bit of regrowth from masses of dead elm at Roud, between Berrycroft and Russell's Farms SZ515802 (2 photos). Larger 2km elms opposite end of Bagwich Lane SZ518813 (photo) message: No eggs found or adults seen, but well worth another look. Isle of Wight - Andrew Brookes volunteered
