North Devon case study

This case study by Dr. Olivia Langmead from the Marine Biological Association focuses on the importance of subtidal sediment habitats in supporting fisheries production. By examining these habitats as nursery areas and their role in sustaining food chains, the research aims to develop scenarios that assess how management practices can influence their value. Key work stages include data collection on human impacts, ecology, and existing management measures, ultimately providing guidance for effective long-term governance and management strategies in the North Devon marine area.

Presentation Transcript

  1. North Devon case study Dr Olivia Langmead Marine Biological Association

  2. 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

  3. Stages of the work • Data gathering • Valuation • Scenarios • Implications for governance

  4. Case study Area

  5. Data collection Data 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

  6. Human activities that leave a footprint on the seabed: Industry

  7. Human activities that leave a footprint on the seabed: Fisheries (1) Finding Sanctuary Fishermap

  8. Human activities that leave a footprint on the seabed: Fisheries (2) Finding Sanctuary Fishermap

  9. Human activities that leave a footprint on the seabed: Fisheries (3) Finding Sanctuary Fishermap

  10. Human activities that leave a footprint on the seabed: Fisheries (4) Finding Sanctuary Fishermap

  11. Human activities that leave a footprint on the seabed: Fisheries (5) • VMS data still to come in from MMO • MMO landings data • Fishermap • Recreational angling surveys MMO/NSA • No data on scallop trawling in Finding Sanctuary Fishermap

  12. Ecology: seabed habitats

  13. Ecology: fish stocks • Cefas Beam Trawl Surveys VIIa/Young fish surveys • EA young fish surveys • Cefas gear trial surveys • IFCA potting surveys • RWE potting and trawl surveys

  14. Ecology: nursery and spawning grounds (1)

  15. Ecology: nursery and spawning grounds (2)

  16. Ecology: nursery and spawning grounds (3)

  17. Ecology: nursery and spawning grounds (4)

  18. Management: site based protection

  19. Management: fisheries measures

  20. Management: nutrients in catchment

  21. 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?

  22. With special thanks to all our partners and funders
