Butterfly Conservation - Upper Thames Branch

10km Square Champions

Every five years Butterfly Conservation produces a national butterfly atlas. In order to achieve coverage across the whole UTB region, the aim is to visit each tetrad (2x2km) of each 10x10km square at least once in each season over the 5-year atlas period. The champion of each square is responsible for carrying out this surveying activity.

The map below shows the 10km squares in the UTB region. If you are interested in becoming a champion, please contact the 10KM Square co-ordinator (Andy Spragg) at 10k-coordinator@upperthames-butterflies.upperthames-butterflies.org.uk

10K squares as at June 2025. Click on a square to show more information.
