Following the Sea Empress oil spill at Milford Haven in February 1996, a census of seabird colonies in south-west Wales was initiated in order to assess the impact of the oil spill on population of seabirds breeding in the affected area. This dataset is compiled of the results of breeding seabird monitoring at colonies in south-west Wales in 1996, 1997 and 1998, the three seabird breeding seasons following the Sea Empress oil spill of February 1996. Data collected in all three years of the project have been compared with data collected in previous years, in order to provide an assessment of the impact of the oil spill on local populations of ten species of breeding seabirds (Fulmar, Cormorant, Shag, Lesser Black-backed Gull, Herring Gull, Great Black-backed Gull, Kittiwake, Guillemot, Razorbill and Puffin).

In all three years of the project census methods and count units used followed the Seabird Monitoring Handbook. Seabird Colony Register Data Forms and 10km Summary Forms were completed for all colonies in the study area, and Colony Register Forms were updated for existing colonies and compiled for new colonies. Completed forms have been submitted to the Joint Nature Conservation Committee (JNCC).
