Severn Estuary SPA High Tide Wintering Waterbird Roost study

Abstract

Identification of wintering waterbird high tide roosts on the Severn Estuary SSSI/SPA completed in four phases:Phase 1 includes the Brean Down to Clevedon stretch. Phases 2 & 3 were completed at the same time. Phase 2 included the Clevedon to Oldbury stretch and Phase 3 Bridgwater Bay. Phases 2 & 3 also identified the subsites within Steart Marshes in Bridgwater Bay.Phase 4 includes the Gloucestershire area.This is a spatial dataset that identifies the locations of waterbird high tide roost sites in the Severn Estuary; and characterises the habitat(s) and waterbird composition. Information on the presence of waterbirds and their roost site characteristics was collected for each sector from the following sources: (i) WeBS core count (ie, high tide) data supplied by the BTO; (ii) interviews with the relevant WeBS counter; and (iii) site visits. This study provides much more detailed information than is generally available for the BTO collected WeBS data. The roost locations will help to determine whether the activities associated with a proposed plan or project could lead to impacts which have a significant adverse effect upon any given species or assemblage of water bird(s).

Quality and validity

Lineage

Information pertaining to the presence of waterbirds and their roost site characteristics was collected by WeBS core count (ie, high tide) data supplied by the BTO, interviews with the WeBS counters for the study area and site visits to each of the sectors within the study area (OGL). The spatial data was based on Ordnance Survey products (1:10,000 Scale Colour Raster, OS 1:25,000 Scale Colour Raster, OS MasterMap ® Address Layer 2, OS Mastermap ITN (Integrated Transport Network), OS MasterMap Topography LayerOS Mastermap). However, due to the small amount of Ordnance Survey data used it was deemed appropriate to put it through the Presumption to Publish process and release this data as open government licenced data.
