How effective has the management of Cockle and Mussel fisheries on The Wash estuary been in ensuring that there is sufficient food for birds?
Author: Kirkland, M., Atkinson, P.W., Clark J.A. & Robinson, R.A.
Published: Winter 2024
The Wash is England’s largest Special Protection Area, with Oystercatchers being a designated feature. During the winter, Oystercatchers rely heavily on Cockles and Blue Mussels for their food requirements, creating the potential for conflict with the human fisheries for these species.

Silvopasture Biodiversity – Beetles and Bats: providing the infrastructure and protocols that farmers can follow to participate in biodiversity monitoring using passive acoustic monitoring
Author: Newson, S.E. & Gray, A.
Published: 2024
Working with the Devon silvopasture network, a survey and sampling protocol was devised that allowed farmers to deploy static acoustic bat detectors over a seven month survey season to provide baseline data for bats. This report provides an overview of the survey coverage and main results from 2023, to highlight what can be delivered now using passive acoustic monitoring, whilst providing the next steps and a vision for the future.

Population and distribution change of Eurasian Woodcocks Scolopax rusticola breeding in the UK: results from the 2023 ‘Breeding Woodcock Survey’
Author: Heward, C.J., Conway, G.J., Hoodless, A.N., Norfolk, D. & Aebischer, N.J.
Published: 2024
Although the Woodcock is one of the world’s most abundant wading birds, Britain’s resident population has been declining since at least the end of the 1960s. Periodic Woodcock surveys began in 2003 and have been repeated in 2013 and 2023. This paper reports on the latest of these surveys.
