European grassland butterfly indicator
A new report entitled The European Butterfly Indicator for Grassland Species: 1990:2007 has recently been produced by De Vlinderstichting (Dutch Butterfly Conservation) and Butterfly Conservation Europe and is based on data from fourteen national Butterfly Monitoring Schemes.
The European Grassland Butterfly Indicator shows the population trend of butterflies which are characteristic of grasslands. Since 1990 the European Grassland Butterfly Indicator shows a strong negative trend and has declined by almost 60%.
