Mesoamerican Reef

The Mesoamerican Reef (MAR) Ecoregion features the largest barrier reef system in the Atlantic Ocean.

A magnificent assemblage of coral reefs, mangroves, seagrasses, and coastal lagoons, the MAR extends for several hundred miles from the northeastern tip of Mexico’s Yucatan Peninsula to Belize, the eastern coast of Guatemala, and the northern coast of Honduras (click on map to enlarge).

More than two million people directly depend on the integrity and health of the MAR for their livelihood, and the national economies of Belize, Mexico, and Honduras benefit substantially from the Reef’s appeal as an international tourist destination.

Our long-term goal is to ensure that the MAR thrives as a healthy, productive ecosystem capable of supporting vibrant economies and providing abundant marine resources for generations to come. Six objectives drive our grantmaking.
