Record Mapping - Herts & Middx Butterfly Conservation

Butterfly Mapping 2020 - 2024

Butterfly mapping is an enjoyable form of recording. It should be done in fine, warm weather, and it gets you to different places you would never otherwise think of visiting, and gives you the best opportunity of making important discoveries in far-flung corners of the countryside.

In 2020, (the first year of our current mapping period) we had quite good coverage, considering the restrictions we were under. However about a third of the records were from the Big Butterfly Count which, although valuable, only runs for three weeks a year and is therefore somewhat limited in the species covered. The map below excludes BBC records and shows the under-recorded areas which we need to target across the whole year. It is too early in the 5 year period to identify a list of individual 2km squares but we can point out some general areas for survey.

On the map the white areas are the best covered with at least 10 species present, so we need to concentrate on the coloured dots which highlight the areas for action, the largest dots are those where we have no records at all. In general terms north-east and north-west Hertfordshire and south-west Middlesex are the least well recorded areas.

Should you wish to target an area please contact Andrew Wood who can provide more details to help you search and ensure that effort is not duplicated.
