Ground Monitoring of Common Scoter Melinitta nigra in Carmarthen Bay (2010 - 2011)
Carmarthen Bay Spatial Protection Area (SPA) was classified as the UK's first SPA in 2003 on the basis of holding at least 1% (16,000 individuals) of the biogeographic population of Common Scoter (Melanitta nigra). The Common Scoter is strongly migratory and often travels considerable distances over land making brief stop-overs on inland waters. Its diet consists predominantly of molluscs, especially during the winter, although it occasionally takes other aquatic invertebrates such as crustaceans (e.g. barnacles and shrimps), worms, echinoderms, isopods, amphipods and insects (e.g. midges and caddis flies) as well as small fish and fish eggs which are found in abundance in the shallow water in Carmarthen Bay. Common scoter are also listed as a Biodiversity Action Plan (BAP) species. Countryside Council for Wales (CCW) has supported ground based counts since 1996, following the Sea Empress oil spill. This work feeds in to the condition monitoring and surveillance of Carmarthen Bay SPA and contributes to Common Standards Monitoring.

Three ground counts of common scoters (and other species) were made in Carmarthen Bay between December 2010 and February 2011. These sites were Pembrey Sand Dunes, Dolwen Point near Pendine and Merrifields, Amroth. An additional site at Spaniard Rocks above Burry Holms was visited in January and February to check scoter abundance. Burry Holms was favoured above the count station at Kitchen Point, Rhossili, which has previously been used, as 10,000 common scoter had been recorded from this location on 2nd January 2011. 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.
