Distributions of wintering waterbirds and seabirds in Liverpool Bay/Bae Lerpwl area of search 2025

Abstract

This dataset provides distribution data (Kernel Density Estimates) for waterbirds in the Liverpool Bay/Bae Lerpwl area. The methods used to generate these shapefiles can be found in JNCC Report 576.

The UK SPA selection guidelines for the identification of SPAs advise that sites should be identified in two stages (Stroud et al 2001). While Stage 1 identifies areas that are likely to qualify for SPA status, Stage 2 further considers these areas to select the most suitable areas in number and size for SPA classification. The data presents the distribution of wintering aggregations of inshore waterbirds and indicates if species exceed their respective population thresholds under the UK SPA Selection Guidelines within the area of search.
