Help us save Somerset's threatened butterflies

Large Blue_Keith WarmingtonMany butterfly species are in rapid decline across the UK due to a long-term loss of grassland and a series of consecutive wet summers. Despite conservation efforts, Grizzled Skipper, Large Blue and Small Pearl Bordered Fritillary remain a cause for concern in Somerset.

For many years, Somerset Wildlife Trust has been working to restore, recreate and enhance butterfly habitats on its reserves across the county, but the recent dramatic decline in butterfly numbers is an urgent cry for help that requires us to step things up a gear. Butterflies such as the Pearl Bordered Fritillary (not to be confused with the Small Pearl Bordered Fritillary) are already extinct in Somerset.

We need your help to raise £30,000 to fund equipment and staff time to stop more of our iconic butterfly species heading the same way.

Please help to make Somerset a place where butterflies thrive once more. Thank you.

The plight of Somerset's butterflies

Small Pearl Bordered Fritillary

Small Pearl Bordered Fritillary

Small Pearl Bordered Fritillary butterflies were once widespread across Somerset. In the early 1990s, as many as 50 individual butterflies were recorded on our Langford Heathfield nature reserve over a single flight period. Despite positive management, 2012's dreadful weather caused this number to drop to 15, and this year only six butterflies have been recorded. April - July 2013 is widely considered to be the worst period in recent years for these species.

The Large Blue butterfly is one of the world's most threatened species - it is incredibly sensitive to poor weather conditions and needs very careful management. Prior to their reintroduction to Somerset Wildlife Trust's Green Down nature reserve in 1992, Large Blue butterflies had been extinct in the UK. We now host the largest colony in the world, enabling colonisation of some smaller, satellite sites. Despite this success, Large Blue butterflies remain vulnerable, as evidenced by the 50% decline in egg numbers on our Green Down nature reserve twelve months on from the incredibly wet summer of 2012.

 Grizzled Skipper

Grizzled Skipper

Grizzled Skipper butterflies are a good indicator of landscape-scale, species-rich, calcareous grassland. Monitoring over the last 10 years has indicated that where land has been positively managed for Grizzled Skippers, their population has remained stable. This is not the whole picture though, as while on good sites the population has remained stable, habitat fragmentation leaves the species vulnerable to local extinction.
