The WCBS is a 'light touch' recording scheme for monitoring butterfly numbers across the UK. Results from these surveys feed into national statistics that inform policy makers about the health of the environment. Further information about the scheme and reports on previous years' surveys can be found here
Volunteers take 'ownership' of a randomly selected 1km OS grid square, walking two parallel transect lines through the square at least once in July and once in August, identifying and recording any butterflies seen. Walks need to take place in good weather and follow the same methodology used for butterfly transects.
No experience is necessary - just an interest in butterflies, a willingness to learn, normal eyesight and the ability to get to and from the square and to walk the route safely.
Because squares are selected randomly they can cover any type of habitat, including urban areas and farmland as well as more natural areas. In some cases the landowners permission is required before walks can take place.
A number of squares have been identified in Hampshire and the Isle of Wight which require walkers for 2024. These are listed below, with approximate locations. If you are interested in getting involved in butterfly recording and would be able to undertake two walks a year (one in July and one in August) at one of these locations please contact email (wcbs.AT.hantsiow-butterflies.org.uk).
