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

Trade-offs between the natural environment and recreational infrastructure: a case study about peatlands under different management scenarios

Land use policy seeks to manage benefits for different groups within society by balancing competing interests. These benefits could be the delivery of food through agriculture or the provision of recreational opportunities; they may also be less tangible things, such as carbon storage or flood mitigation. An important component of balancing these competing interests is to understand their relative importance to different parts of society, something that is addressed through this collaborative paper including BTO, which uses peatland restoration as an example.

Modelling important areas for breeding waders as a tool to target conservation and minimise conflicts with land use change
Author: Calladine, J., Border, J., O’Connell, P. & Wilson, M.
Published: 2022
The future of Britain’s breeding wader populations depends on land use policy and local management decisions, both of which require robust evidence and appropriate tools if they are to support the conservation of these priority species. One of the biggest challenges has been the geographical scale at which national data on wader abundance and distribution are available. These data are coarse in their resolution, making them poorly suited to directing conservation initiatives or informing land management decisions at a local scale. But can a statistical approach produce high-resolution maps of predicted wader abundance that are sufficiently accurate to be used for decision-making?
