This study uses GPS tags, fitted to adult Curlews in the Yorkshire Dales National Park, to infer nest and brood locations and breeding outcomes from movement patterns of the tagged birds.

Working with a network of volunteer fieldworkers, static acoustic bat detectors were deployed over four survey seasons (2021–2024) to provide baseline data for bats on the islands of Guernsey, Alderney, Herm, Sark, Brecqhou, Burhou, Crevichon, Jethou and Lihou. This report provides an overview of the survey coverage and main results from the project.

This report presents results from the first year of passive acoustic monitoring as part of the pilot of the Rewilding Monitoring Framework. These data will contribute to baselining and monitoring rewilding progress on the Hepple Estate and its impact on biodiversity.

Estimates of breeding seabird populations are used to assess the potential impacts of proposed wind farm developments. The approach used in these assessments is known as the Biologically Defined Minimum Population Scales (BDMPS) method, and it was developed by Furness in 2015. This report evaluates the methods developed by Furness, and highlights potential refinements to the current BDPMS approach, including methods, definitions, and data resources, to improve future ease of use and accuracy of estimates.

This report was commissioned by the Northern Ireland Environment Agency to scope the evidence available on the movements and spatial distributions of certain marine birds in and around Northern Ireland waters, in order to identify knowledge gaps. The focus is on 37 marine birds found offshore, away from the coastline, that utilise the Celtic Seas (OSPAR Region III) and Ireland Exclusive Economic Zone marine environments. Metadata from 10 different sources (including directly contacting researchers, a literature review and accessing several archived datasets) are used.

This report investigates the efficacy of methods for producing population trends from BTO/JNCC/RSPB Breeding Bird Survey data for six breeding wader species in the UK. It examines the effects of increasing the count threshold on the population trends for these six species, and also explores the effects of different geographic exclusion rules on the population trend of Golden Plover. Overall, it aims to test for any potential biases in the current trends, and in doing so, determines whether we can create a better approach which provides the most robust data for wader conservation moving forwards.
