Ground Monitoring of Common Scoter Melinitta nigra in Carmarthen Bay 2009 - 2010
Carmarthen Bay Special Protection Area (SPA) was classified as the UK's first SPA in 2003 on the basis of holding at least 1% (16,000 individuals: Wetlands International 2006) of the biogeographic population of common scoter Melanitta nigra. Common Scoter feed on bivalves and other invertebrates such as polychaetes and amphipods which are found in abundance in the shallow waters ( less than10m) in Carmarthen Bay. Common scoter are also listed as a BAP species. Purpose of data capture was to collate data to feed into the condition monitoring and surveillance of Carmarthen Bay SPA and contributes to Common Standards Monitoring.

Counts were made at 4 locations: Rhossili, Pembrey, Pendine and Amroth. Rhossili was visited at least once and the other sites at least twice. Methods for counting are outlined in Banks et al (2004, 2007). All relevant local conditions were recorded and counts were only taken during suitable weather and visibility conditions and where possible counts coincided with high tide. An experienced counter using high quality binoculars and telescope was employed. However, no spatial reference were provided with data for statistical analysis. It is assumed for the purpose of the metadata that samples were collected using British National Grid.
