Wider Countryside Butterfly Survey

Admiral Sky

Nationwide survey continues in 2013.

There is growing acknowledgement of the importance of biodiversity in the wider countryside. Butterfly populations are an excellent way to monitor the health of an environment.

UK butterfly monitoring currently focuses on nature reserves and butterfly-rich places. This has lead to a lack of monitoring in vast areas of the wider countryside. These areas include farmland, plantation woodland, uplands and urban green spaces

The UK Butterfly Monitoring Scheme, run by Butterfly Conservation and the Centre for Ecology and Hydrology, has developed a new Wider Countryside Butterfly Survey (WCBS) method to gauge the changing abundance of widespread species in the general countryside.

70% of the UK’s land is in agricultural use. It is essential that butterflies in these areas are monitored to gauge the health our countryside.

Over 600 dedicated volunteers surveyed more than 760 squares as part of the nationwide WCBS launch in 2009. The WCBS benefits from an excellent partnership with the British Trust for Ornithology Breeding Bird Survey recorders surveying roughly half of the squares last year.

What's involved?

The new method involves making a minimum of two visits to a randomly selected square near between May and August to count butterflies along two 1km survey lines running roughly north-south through the square. The survey will be co-ordinated centrally by Butterfly Conservation but with the help of a WCBS Champion in each Branch. The aim for 2013 is to resurvey all squares covered last year and more so if you would like to take part please get in touch.
