Atlas species distribution map example
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.
The butterfly records that we collect are cumulated nationally every five years, at the end of which period recording starts again. Our oldest butterfly records date from 1970. Twenty-first century cycles started with 2000-2004.
The species pages listed below give a major analysis of both long and short term data for Dorset’s butterflies from 1970 to 2019.
