BTO Research Reports are scientific papers that have been self-published by the BTO. The following is a full list of the published BTO research reports. Most are free to download, and links to Abstracts are included where possible.
Numbers missing from the list are those allocated but which were never produced or which have not been published. BTO recognises that, particularly in respect of commercially sensitive cases, a period of confidentiality is appropriate for some projects. However, in the interests of scientific development and dissemination of information, we encourage clients to permit publication as soon as it is reasonable to do so.

Assessment of recent Hen Harrier population trends in England through population modelling
This study uses a population modelling approach to explore the effects of changes in rates of productivity, survival, and settlement on population growth in the English population of Hen Harriers.

The effects of a decade of agri-environment intervention in a lowland farm landscape on population trends of birds and butterflies
Author: Redhead, J.W., Hinsley, S.A., Botham, M.S., Broughton, R.K., Freeman, S.N., Bellamy, P.E., Siriwardena, G., Randle, Z., Nowakowski, M., Heard, M.S. & Pywell, R.F.

Food production and wildlife conservation are often thought of as incompatible goals, and it is rare that conservation studies consider both economics and long-term changes in ecology. However, a decade-long study at a commercial arable farm in Buckinghamshire has found that agri-environment schemes significantly increased local bird and butterfly populations without damaging food production, offering hope for the UK’s farmland birds and butterflies.

Marine Protected Areas are designated to protect marine fauna, such as whales, sharks, turtles and seabirds, but are we getting them right? Tracking data provide valuable information on the movements and space use of species, so can these be used to help us plan and deliver better protected areas for marine magafauna and their habitats?
