Jolyon Chesworth on Marine Conservation at Cafe Scientifique

  1. 1. The Science of Marine Conservation ZonesBeneath the Waves;Marine conservation in the Solent Jolyon Chesworth Marine Conservation Manager 12th March 2012
  2. 2. Outline • Why we need MPAs • Benefits of MPAs • Protected area designations • Marine Conservation Zones • Balanced Seas stakeholder process • Site selection science • Ecological data • Management measures
  3. 3. Habitats
  4. 4. Species
  5. 5. Resources and impacts
  6. 6. Ovefishing 1900 1999
  7. 7. Marine Protected Areas • Area of sea / seabed designated to protect or conserve habitats and or species • May be designated for specific habitats and species or full range • May be multi-use or highly protected • Statutory• Voluntary – SSSI’s – terrestrially focused – Biodiversity Action Plans – Ramsar – wetlands of international – Marine SNCI’s and importance conservation areas – Natura 2000 sites – Voluntary agreements – Marine Conservation Zones
  8. 8. Benefits of MPAs – inside boundaries• Heavily fished species show most dramatic increases• Non-target species can increase is habitat is protected• Bigger individuals inside MPAs produce more young compared to smaller individuals outside of MPAs
  9. 9. Benefits of MPAs – outside boundaries
  10. 10. Case studies - Bradda Inshore Fishing Ground
  11. 11. Case studies – Lundy Island
  12. 12. Case studies – Lyme Bay
  13. 13. Marine and Coastal Access Act 2009• Marine Conservation Zones• Objectives – Avoid deterioration – Enable recovery of habitats and populations• National importance out to 200nm• Improvement of wider sea management
  14. 14. Balanced Seas• Under MCAA 4 regional MCZ projects• Balanced Seas Project structure – Regional Stakeholder Group – Local Groups – Site Meetings – Science Advisory Panel
  15. 15. Site selection• Ecological Network Guidance• 7 principals: – Representativity – Replication – Adequacy – Viability – Connectivity – Best Available Evidence – Protection• Reference Areas
  16. 16. Habitats and Species• 21 Broad Scale Habitats• 22 Habitat FOCI• 29 Species FOCI Stalked jellyfish Haliclystus auriculaFragile sponge and anthozoans Sea-pens and burrowing megafauna
  17. 17. Ecological data
  18. 18. Seabed habitat maps
  19. 19. Wildlife Trust site submissions
  20. 20. Key inshore sites
  21. 21. Where are we now - Final Recommendations• 30 rMCZs• 25 Reference Areas
  22. 22. Key Inshore Biodiversity Areas with rMCZs
  23. 23. Progress towards selection criteria
  24. 24. Vulnerability Assessment and Conservation objectives • Maintain – means that in general current levels of activity are considered acceptable, but they will be monitored and restrictions may have to be introduced if necessary. • Recover – means that restrictions on certain activities may be necessary to allow the feature to recover to favourable condition. It does not necessarily mean that an activity will be prohibited, as other mitigation measures might be appropriate.
  25. 25. Concerns• Influence of socio-economics – Many sites below minimum size – Some important sites lost• Activity data often poor – Leads to business as usual and little conservation gain• Will they all be designated?• Will they make any difference?
  26. 26. Petition Fish
  27. 27. Questions?
