North Devon case study
Dr Olivia Langmead Marine Biological Association
Focus of the study• Subtidal sediment habitats and
their value in supporting fisheries production
• The valuation research will consider the role of sediment habitats as nursery areas and in sustaining food chains (food supply for fish)
• Scenarios will be developed (with you!) to determine how values might change under different plausible management scenarios
• We anticipate that this work will be of direct benefit for the long term management of the area
Stages of the work
1. Data gathering2. Valuation3. Scenarios4. Implications for
governance
Case study Area
Data collectionData have been collected on: Human activities and uses
that affect the seabed – their distribution and intensity in the NDBR marine area
Ecology – seabed species and habitats, nursery and spawning areas for commercially important fish species and reported catch
Management – existing measures including MPAs, fisheries restrictions

• These maps show what we know about– human activities– Ecology –Management
• Do they match up to the real life situation?
• What are we missing?• How can our understanding be
improved?
