Ecosystem services mapping in the Severn estuary and inner Bristol Channel 2014-12-01 publication DASSHDT00000075 The study aimed to assess and map the delivery of key ecosystem services (ES) within the greater Severn estuary and Bristol Channel. The project aimed to provide a tool for stakeholders, regulators and the marine renewable industry to support decision making in the region. Identification of hotspots for key ES was intended to provide developers with an insight into locations with a high consenting risk.

The region was divided into 10km2 hexagonal "planning" cells. Habitat, species presence and bathymetry were the key environmental variables responsible for determining the delivery of environmental benefits. Habitat and species data were supplied from MESH, JNCC and Natural England, and a habitat / species confidence score assigned to each cell based on data availability: 1 - Least detailed. Data provided from JNCC UKSeaMap. Broad-scale predicted (modelled) substrate types derived in the absence of full surveys. 2 - Next most detailed. Data provided actual substrate type from derived surveys. 3 - Most detailed level. Data derived from surveys containing sediment type, tidal information and species presence. Bathymetry data - derived from admiralty charts from EDINA. Less than 2m, 5m and more than 5m contours were digitised.
