Following on from Phase 1 (Figure 1), the aim of this project is to provide evidence of the location and nature of wintering waterfowl high tide roosts, the bird assemblages associated with these roosts and the relative size and importance of the roost sites to key species, in the Severn Estuary.
Capture the knowledge of local BTO webs counters
Map the roost location of the SPA birds
Describe the SPA bird assemblage at each roost
Record the characteristics of each roost (e.g. habitat or feature)
