The plight of Britain’s rare butterflies and moths is to be tackled by the Forestry Commission in an attempt to boost their dwindling numbers in the nation’s woodland. They have teamed up with Butterfly Conservation and have identified 140 key sites which need action, 77 of those have been designated grade A priority sites as they are home to some of our rarest species, such as the Pearl-bordered Fritillary, and the Argent & Sable moth.
