EAST GLAMORGAN BIRD ATLAS

In November 2007 the BTO, in partnership with the Scottish Ornithologists' Club and Birdwatch Ireland, began a project aimed at producing new distribution and abundance maps in a National Atlas, covering both winter and breeding seasons, for the period 2007-2011. Participation in this survey presented the opportunity to gather data suitable for a local atlas as the basic survey recording unit was the tetrad (2 km by 2 km OS grid square)... The species distribution maps show the results from 4 surveys. Three of them were carried out on a national scale, driven by the BTO, with the data supplied by them under an agreement with the Glamorgan Bird Club. The other was a locally organised survey. The maps for some species, especially raptors, show distributions at the 10km square level only or not at all in order to avoid divulging sensitive information especially of breeding locations for protected or scarce species...
