History
• Type – Fringing reef • Composition – five reef flats separated by
deep channels• Size – 7 km² (30ml²)• Main Corals found – star or boulder coral• Designated as MPA in 1973• Nylon Pool, No Man’s Land, Bon Accord
lagoon• >30 projects have been conducted

Legislation and Guidelines
• Marine Protection Act (1973)
• Environmental Sensitive Areas Act (2005)
• RAMSAR Convention (2006)

Contributors to Reef Growth
• During Wet Season, Orinoco River’s nutrients give nourishment to reef.
• Guyana currents which dilute the Orinoco River’s nutrient content.

Bleaching Event in 1995
• 88 sites were observed in 2005 for bleaching• Overall mean bleaching was at 66% with 71% mean at
deep sites and 63% mean at shallow sites• Some coral species exhibited greater tolerance to
bleaching such as M. annularis• Elkhorn coral seemed to be impervious to bleaching

Effects of Climate Change
• Bleaching event in 1995
• In a 2005 study, mean bleaching of hard corals was 66%
![Page 13: AL LAN GU Y Bsc](https://reader030.fdocuments.in/reader030/viewer/2022013011/56813b02550346895da3a356/html5/thumbnails/13.jpg)
Successes

Mooring and Buoy Installation
• Protects reef from boat
anchors
• Demarcates reef
![Page 15: AL LAN GU Y Bsc](https://reader030.fdocuments.in/reader030/viewer/2022013011/56813b02550346895da3a356/html5/thumbnails/15.jpg)
Education
• Increases awareness
• Reduces destruction of reef
• Increases community involvement and action
• Increases funding
![Page 16: AL LAN GU Y Bsc](https://reader030.fdocuments.in/reader030/viewer/2022013011/56813b02550346895da3a356/html5/thumbnails/16.jpg)
Water Quality Monitoring
• Keeps water within acceptable limits
• Reef stress may be identified easier
• Advise on management of land uses
![Page 17: AL LAN GU Y Bsc](https://reader030.fdocuments.in/reader030/viewer/2022013011/56813b02550346895da3a356/html5/thumbnails/17.jpg)
Reef Checks
• Checks health of reef, benthic coverage, etc.
• Comparisons can be made between reefs to better understand the growth pattern, why some corals are dominant in one area, etc
![Page 18: AL LAN GU Y Bsc](https://reader030.fdocuments.in/reader030/viewer/2022013011/56813b02550346895da3a356/html5/thumbnails/18.jpg)
