Transect recording in Hertfordshire & Middlesex
Link sections on this page . . .
Just under 60 transects are currently being
walked in Hertfordshire and Middlesex.
A route should take about 30 minutes to walk when there are no butterflies, as this will expand to more than an hour at the height of summer. A good length is between 1-3 kilometres (up to about 2 miles). The route is divided into sections that correspond to particular habitats and there can be up to 15 sections.
This method gives information on the variation in butterfly numbers within the season, and from year to year and can also be invaluable in helping to guide and review management for butterflies on a particular site..
The route must be walked in set weather conditions:
Records are ideally submitted each week onto the online Transect walker website at: http://www.ukbms.org/mydata/. Registration is needed to use this site and to register a transect if it is a new one.
If you do not have any computer access records can be submitted on paper sheets and sent to Andrew Wood at the end of the season.

Using the online system is preferred as it saves errors generating by transcribing handwritten records.
