Ecosystem services in the NDBR

Using Ecosystem Services in Management
Understand the level of key services delivered by NDBR habitats
Evaluate how service delivery changes under different management scenarios
Compare outcomes and consider trade-offs
Understanding the delivery of key servicesHabitat Service Benefit
Nursery habitat
Waste processing
Carbon burial
Our approach
Step 1 – Literature review
• water depth
What do juvenile fish need?
• sediment type
• food sources
Our approach
Step 1 – Literature reviewWhat species/processes control regulating services? • bioturbation: how species rework the substrate
Our approach
Step 2 – Local survey data
What substrates/species are present?
• PML (1973)• National Museums & Galleries of Wales (2003)
• RWE (2011)• Environment Agency (2008, 2010, 2013)
Step 3 – Link to habitat typesTo allow services to be mapped across the NDBR
Findings
Good links between sites and habitats for remediation
Links between biological traits and habitats not clear
Fisheries species food preferences are too general
but….. only where species information is present
so........ carbon sequestration mapped by just substrate
so........ not included in the assessmentand..... mapped by just substrate/depth
Hoping for validation through input from fishers

Aggregation and trade offs
How should we represent the occurrence of multiple services in the same place?
What happens when the effects of management interventions occur in opposite directions for different services?
Aggregation and trade offs
Just an EXAMPLE – based on equal weighting
Weighting ecosystem services
