Survey coverage of Somerset is far from complete . The following list shows the number of 1km squares unrecorded for 7 years or more by 10km square as at the start of the 2018 season.
If you click on the 10km Square id. below you will see a list of all the unrecorded 1km squares in that 10km square.
The map below shows the squares that have been recorded in since 2010 and the blank squares are those where we still need records.
