Presentation Transcript

  1. Non-destructive Biodiversity Monitoring of Marine Protected Areas • A flying array using High Definition Video • Prof Martin J Attrill • Director, Plymouth University Marine Institute, UK • mattrill@plymouth.ac.uk • @mjattrill

  2. Marine Protected Area implementation in UK waters 127 Marine Conservation Zones: England (2009 Marine Act) 108 Special Areas of Conservation (EU Habitats Directive) Lyme Bay Designated 2013 On Hold for further evidence 20 miles

  3. MPA implementation in UK waters: Lyme Bay 2008 • First large MPA in UK was 200 km2 Lyme Bay closure to mobile gear • Protect reef features from trawling and scallop dredging • We developed methodology for monitoring seabed change in this (and other) MPAs • Data since 2008

  4. Plymouth University Marine Institute Flying Array • Towed behind fishing vessel at 0.5 kt • Maintains itself just above seabed: drag chain • HD video camera, lights and scaling lasers • 200 m transects (large organisms) • Analyse whole transect or random frame grabs (detailed community analysis)

  5. PUMI Flying Array: value of HD video Example of HD resolution video stills grab from marine organisms ID organisms on Davy Jones’s Hat

  6. PUMI Flying Array: Operation

  7. PUMI Flying Array: Operation • Video clip 1 here

  8. PUMI Flying Array: Example Results Species Richness: Frame grabs MPA MPA Abundance Outside Outside

  9. Enumerating Mobile Organisms: Baited Remote Underwater Video • Deploy HD video cameras on frames to seabed • 3 BRUV cameras per site • Bait (mackerel) in baitbox • Film after settling for 30 mins • Record all organisms seen – use maximum abundance

  10. Enumerating Mobile Organisms: Baited Remote Underwater Video • Video clip 2 here

  11. PUMI Flying Array: summary • Non-destructive: vital in Marine Sanctuaries • Cost-effective: cover far more ground than divers • Deployable from small boats (fishing vessel) • Samples form library so can always be reanalysed • We’ve deployed down to 60m, in rocky areas and high tidal stream site • Technology taken up by institutions in UK and France C4 Hugh’s Fish Fight Dr Emma Sheehan
