Evaluating terrestrial bird trends for Welsh Statement Areas 2022
National-scale biodiversity monitoring schemes, such as the BTO/JNCC/RSPB Breeding Birds Survey (BBS), are designed to provide coverage of a broad range of common species, however, the implementation of conservation policy is increasingly devolved, creating a desire to repurpose data from national biodiversity monitoring schemes to provide information at smaller spatial scales, such as English Natural Character Areas or Welsh Statement Areas.
This report compared the ability of three modelling approaches to derive area-specific trends for the terrestrial Natural Resources Wales (NRW) Statement Areas, for 61 species of bird. This included all 60 species for which Welsh BBS trends are currently reported for at least one time interval, and additionally Pied Flycatcher, which falls just short of the country-level BBS reporting threshold.
