European red list of Butterflies
This study shows us that nearly 9% of butterflies are threatened and a further 10% are Near Threatened. These figures represent minimum estimates as trends are poorly known in many countries, especially eastern European countries which account for a large part of the territory. Despite this limitation, the results show that almost a third (31%) of the butterflies have significantly declining populations. Unfortunately, the drivers for these declines are mostly still in place. The loss and decline of their habitat poses the main threat, either in relation to intensification of agriculture or abandonment of land
