This page presents the current statistics on the BOS Monthly Records database.

Our electronic records start from 1982 and we have currently have 261,832 records (up to 2017). The following charts present the annual status of the records, showing:

  • The number of records submitted each year
  • The total number of species recorded each year
  • The number of grid squares records come from. Note that the BOS surveys 1200km2 , so the charts show that recording comes from over 50% of the BOS area, a remarkably good rate of coverage
  • The number of named sites. Site names have been standardised since 2016 which allows us to better assess the number of sites visited.
