Butterfly Atlases

A guide to Dorset butterfly populations over time

Butterfly distribution atlas

Our Butterfly Atlases are vitally important because they show the location of species and, over time, measure distribution changes and the possible effects of climate change. This gives us the information we need to help various species in appropriate ways.

We are very grateful to all those who gave their time to collect, verify and collate this valuable butterfly data.
