How are Dorset’s butterflies doing?

In order to help butterflies, we need to know about them first. If you haven’t spotted our Distribution Atlas pages yet, do go and have a look at them; they can be accessed via our ‘Recording‘ page.

Our Records Officer, Bill Shreeves, has done a magnificent job taking both a long-term and short-term view of our records from 1970 to 2014, showing how the various species have fared in Dorset. Each species has a distribution map of sightings between 2010 and 2014, followed by information showing population trends.

This is still a work in progress. We will be adding Dorset flight-time charts soon, and Bill is working on further ways of illustrating trends, and hopefully we may be able to crunch the numbers to achieve some abundance data, too.
