Butterflies associated with old pasture, meadow and marshy land have been in sharp decline for some years. That's partly due to habitat loss and partly due to factors which are not well understood, like increasing atmospheric nitrogen deposition, and the increasing distance between remaining habitat patches.

During May, June and July please take the time to go and look carefully on any old, flower-rich wet or rough grassland or marshy land on your holding - and let us know what you find!
In particular the following species are most threatened:
