South East Scotland Tetrad Atlas 2007 - 2013 - non-sensitive winter species
Scottish Ornithologists' Club, The
Description
Records for all bird species recorded during the 6 survey years 2007-13.
Geographic Description
All records come from the Lothian and Borders Recording areas (see http://www.the-soc.org.uk/soc-recorders.htm). The survey covered all 1770 tetrads, comprising 7000 sq km, of the South-east Scotland area covering the Borders and Lothians. Habitats include the city of Edinburgh, the Tweed Valley, heather moorland and the sea cliffs of Berwickshire.
800 volunteers collected some 92,000 records on 168 species. Recording effort was probably greatest around population centres, but this has not been quantified.
Purpose
The aim of the survey was to build a complete picture of all the winter birds of the Lothian and Borders recording areas during 2007-13 at tetrad scale. Much of the survey work was carried out at the same time as the BTO national breeding atlas.
Data quality
The data are of high quality, having been checked and verified by the Lothian and Borders recorders and the respective Atlas Working Groups.
Methods
Data were collected during systematic surveys of all the tetrads in the Lothian and Borders recording areas. All records have been validated by the respective Local Bird Recorders and/or the Tetrad Atlas working groups. All records are geo-referenced at the tetrad (2x2 km scale). The ‘count’ field records the maximum count of each species in the tetrad over the entire survey period (both TTVs and Roving Records).
