Title

2014 NERC Marine Renewable Energy Knowledge Exchange Project. Ecosystem services mapping in the Severn estuary and inner Bristol Channel

Abstract

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.

Lineage

Six ecosystem services and related benefits were selected for supply level mapping, chosen by the project steering group from the known services provided by the Severn estuary and the inner Bristol Channel: Carbon sequestration (regulating service) Food alleviation (regulating service) Fish - migratory fish (provisioning service) Wet archaeology (cultural service) Sense of place (cultural service) Port and shipping (carrier service) Levels of supply were then established based on those described in "Potts, T., Jackson, E., Burdon, D., Saunders, J., Atkins, J., Hastings, E. and Langmead, O. 2013. Marine Protected Areas and Ecosystem Services – Linking Conservation and Human Welfare? Unpublished report of the NERC-funded Valuing Nature Network, January 2013, UEA, Norwich.29pp" and "Potts, T., Burdon, D., Jackson, E., Atkins, J., Saunders, J., Hastings, E., Langmead, O., 2013a. Do marine protected areas deliver flows of ecosystem services to support human welfare? Marine Policy 2013." 5 - Significant contribution 4 - moderate contribution (literature referenced) 3 - moderate contribution (expert opinion) 2 - low contribution (literature referenced) 1 - low contribution (expert opinion) GIS mapping - completed using ESRI ArcGIS 10. 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.
