| The Wetland Bird Survey Core Counts are monthly counts of non-breeding waterbirds carried out by volunteers over the period 2004/2005 to 2008/2009. The aims of the scheme are to determine the numbers of non-breeding waterbirds in the UK, their trends and the importance of individual sites for each species. |
| Five character code (NB not always numeric) identifying the count site. Larger sites are subdivided into smaller sections for ease of counting, with data consolidated at a later stage (as provided in this case). |
| Single point approximating centroid position of count location. Work is ongoing to define count polygons for all locations. |
