This file shows the 6 country level charts and data as well as the 1 regional chart. Coral reef health is measured using four indicators: coral cover, fleshy macroalgae, herbivorous fish and commercial fish. The Coral Reef Health Index (RHI) is the average of the four indicators. Each indicator is assessed at the country and regional level for a given year resulting in a score from 0 and 5 and a grade ranging from Very Good to Critical.

A coastline is the area where land meets the sea or ocean. In the case of GIS, it is represented as a line or polygon which forms the boundary between the land and the ocean or a lake. Its use as a base layer allows for the delineation of islands and in some cases political boundaries like an entire country. This file is a mosaic of the highest resolution coastline files available for the 6 members of the Organization of Eastern Caribbean States under the ECMMAN project as well as the 3 additional countries participating in the CMBP, stewarded by the Nature Conservancy's Caribbean Program. See Supplemental Information for country specifics.

The protected area shapefile was compiled by the Nature Conservancy (TNC) with substantial submissions and assistance from 21 different governments with sometimes multiple representatives within a government in the insular Caribbean. The data represents a core dataset in conservation for the region. The Nature Conservancy works to keep this file as up to date as possible and uses it heavily in representing what is protected across the insular Caribbean.

Holds polygons representing the EEZs. This file was created from the world_poli_eez_2014 file and modified by TNC in 3 ways: 1.) All the land cutouts were removed to create whole polygons, 2.) International on land boundaries were added (eg. between DR and Haiti) using lines from The Office of the Geographer’s Large Scale International Boundary Lines and World Vector Shorelines (LSIB-WVS) polygon file, and 3.) the EEZ boundary between Grenada and SVG was manually changed to match local opinion.

This is the 200m contour line extracted from the regional TIN created for the project which was then converted into a polygon. The TIN was created using the highest resolution bathymetry data available for each country mosaic'ed together. The 200m contour line for the 3 CMBP countries was extracted from the 2014 GEBCO gridded bathymetry data.
