The Department of the Environment has co-ordinated the Jersey Butterfly Monitoring Scheme (JBMS) since 2004. The scheme is dependent on a team of unpaid volunteers who count butterflies each week throughout spring and summer at 38 locations across Jersey.
This report looks at the first 10 years' of JBMS data with the aim of finding out more about the overall butterfly population, including:
- the state of health of individual butterfly species
- the relationship between the state of our butterfly population and habitat change in urban and country locations
The results indicate there has been an overall decline in most of Jersey's butterfly populations since recording started in 2004, especially in agricultural and urban sites. However, semi-natural sites, managed for their conservation interest, are mostly doing well.
