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) Designated 2013 On Hold for further evidence 108 Special Areas of Conservation (EU Habitats Directive) 20 miles Lyme Bay
3
MPA implementation in UK waters: Lyme Bay 2008 First large MPA in UK was 200 km 2 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
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) Plymouth University Marine Institute Flying Array
5
Example of HD resolution video stills grab from marine organisms ID organisms on Davy Jones’s Hat PUMI Flying Array: value of HD video
6
PUMI Flying Array: Operation
7
Video clip 1 here PUMI Flying Array: Operation

PUMI Flying Array: Example Results Abundance Species Richness: Frame grabs MPA Outside MPA Outside
9
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 Enumerating Mobile Organisms: Baited Remote Underwater Video

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 PUMI Flying Array: summary C4 Hugh’s Fish Fight Dr Emma Sheehan
