Wider Countryside Butterfly Survey - national link
Return to Recording Introduction Page

Can you spare time on 2 days in July and August to visit a grid square and do two 1km walks to record butterflies? This method is intended to compliment, not replace transects, and enable records from a wide variety of habitats to be collected. Some squares will be rich in butterflies, others less so, but all results will be important.

This survey is done in 1km squares and selected at random by the national survey co-ordinator. The squares are:

How to plan the survey

If you are a surveying a square that has been allocated to you, it will be necessary to establish a fixed survey route through the square The survey route is two parallel 1-km long survey lines across your square (running N-S or E-W), that are subdivided into ten continuous 200m sections numbered 1-10.

Obtaining access to the survey route within squares

A large number of 1-km squares have paths, roads, bridleways or open access across them. This information can be gathered from an OS map and the open access website (www.gov.uk/right-of-way-open-access-land/overview). Unless there is open access to your whole square then it is important that you contact the landowner to gain permission to carry out the survey visits. We advise contacting the nearest dwelling to your square either by telephoning to arrange a visit or by sending them a letter. A letter template is available which outlines the reasons why the surveys are being carried out and what they entail. Click here for a copy of the template

Species identification

Try to identify and separate all species you encounter, including where possible similar species such as Small and Essex Skipper, and the 'cabbage' whites.
