Seabird use of waters adjacent to colonies: Implications for seaward extensions to existing breeding seabird colony Special Protection Areas 2003
Between 10 and 27 June 2001, the JNCC systematically surveyed seabirds in the waters immediately adjacent (up to approximately 5 km from mean low water [MLW]) to six seabird colonies hosting nationally and internationally important numbers of seabird species. These breeding season surveys were conducted from chartered vessels using a strip-transect method of counting.
The data analyses here allowed geostatistical and distance band analysis of the densities and distributions of four seabird species engaged in "active" behaviours, namely common guillemot (Uria aalge), Atlantic puffin (Fratercula arctica), razorbill (Alca torda) and northern gannet (Morus bassanus). This is the first time that detailed surveys of the small-scale distributions of seabirds around British seabird colonies have been undertaken. Quantification of the spatial patterns of seabird species has hitherto not occurred at this scale and at such high resolution.
As the general distribution patterns identified are not site-specific, it is recommended that a generic approach to defining seaward extensions to classified SPAs for common guillemot, razorbill, Atlantic puffin and northern gannet will provide appropriate protection for these species in the waters immediately adjacent to their colonies.
