Bittern Annual Surveys in Britain 1990-2019

This dataset contains results from annual national surveys that are undertaken to monitor the population of booming Bitterns (Botaurus stellaris) in Britain. The Bittern is a species of conservation concern. Breeding bitterns in Britain are typically restricted to reedbed (Phragmites australis) dominated habitat. Regularly-occupied sites and other sites with suitable breeding habitat within the bittern range are monitored for booming males annually.
This survey is coordinated by the Royal Society for the Protection of Birds (RSPB), under the Action for Birds in England (AfBiE) agreement, a conservation partnership between Natural England and RSPB.
