National Bat Monitoring Programme Annual Report 2015

The National Bat Monitoring Programme (NBMP) is an annual series of bat surveys undertaken by thousands of dedicated volunteers, which allow us to monitor changes in British bat populations. The data we collect are used by the Government and conservation organisations to monitor the health of our environment, inform policy and improve the conservation of bats.

This report provides population trends for 11 of Great Britain's 17 resident bat species derived from data collected up to and including summer 2015. Trends are provided at GB-level and also at country-level where sufficient data are available (for England, Scotland and Wales; we have insufficient data to provide trends for Northern Ireland at present). This report also provides information on our survey methods and the factors that are driving changes in bat populations in the UK.
