Grenada is the largest of the three island nation which includes Grenada, Carriacou and Petit Martinique. Carriacou is smaller and located to the northeast of Grenada. Petit Martinique is just to the east of Carriacou. All three islands are volcanic in origin with an active submarine volcano, Kick’em Jenny, found between Grenada and Carriacou. The narrow island shelf supports a variety of coral reefs, seagrass beds, sandy beaches and mangrove stands.
CORAL REEFS OF GRENADA
Grenada has a wide variety of reef types that vary with wave exposure, water depth, and east/west location. On the East coast, there is a wide shallow shelf with low relief patch reefs and extensive hard bottom reefs. The west coast has a narrow shelf with more well developed reefs consisting of high relief spur & groove reefs and higher diversity of biota. The south west coast along Grand Anse has a wider shallow shelf with low relief inshore reefs.
PARTNERS & AGRRA SURVEYS
Together with in-country scientists, managers and partners, we have surveyed 33 reef sites in Grenada and Carriacou between 2005-2015.
In 2016, The Climate-Resilient Eastern Caribbean Marine Managed Areas Network
(ECMMAN) project published six Eastern Caribbean Coral Reef Report Cards – a series of individual reports for the 6 participating countries, which provide an easy-to-understand summary of the state of the region’s marine resources. The Report Cards collate data from 277 comparable coral reef surveys and map in detail 383 km² of coral reefs, 19 km² of mangrove, 286 km² of
seagrass, 44 designated and 50 proposed Marine Managed Areas (MMA).
The Report Cards provide an initial baseline on the current state of the reef and identify
gaps. Reporting this type of information will help track progress in protecting reefs and
inform future monitoring and management. The vision is to produce report cards every
2 years and share data through the CaribNode regional spatial data platform.
In 2014, The Grenadines Network of Marine Protected Areas (GNMPA), AGRRA and SusGren conducted AGRRA surveys and established long-term AGRRA monitoring sites in Moliniere Beausejour Marine Protected Area (MPA) and Woburn Clark Court MPA in Grenada and Sandy Island Oyster Bed MPA in Carriacou. GNMPA is a multinational network of managers and stakeholders from 6 MPAs in Grenada and St. Vincent and the Grenadines
The Nature Conservancy (TNC) and Steve Nimrod of Windward Islands Research & Education Foundation conducted 8 AGRRA surveys in Grand Anse Grenada.
In 2005, The Nature Conservancy and partners conducted 14 AGRRA surveys in Carriacou.
CaribNode, designed by The Nature Conservancy, is an online opensource data platform built using GeoNode technology for datasets, mapping and other geospatial information. CaribNode’s spatial data platform combines Caribbean regional and national data to create resource management tools. The CaribNode’s Coral Reef Assessment Tool demonstrates how standardized AGRRA indicators can be viewed and mapped at various spatial scales to monitor the marine environment and help decision makers.
