Glover's Reef

Glover's Reef is a partially submerged atoll located off the southern coast of Belize, approximately 45 kilometres from the mainland. It forms part of the outermost boundary of the Belize Barrier Reef, and is one of its three atolls, besides Turneffe Atoll and Lighthouse Reef.

The oval-shaped atoll is 32 km (20 mi) long and 12 km (7.5 mi) wide. The interior lagoon is dotted with around 850 reef patches and pinnacles rising to the surface. Major cays include Amounme Point Cay, Northeast Cay, Long Cay, Middle Cay and Southwest Cay.

Glover's harbours one of the greatest diversity of reef types in the western Caribbean.

A large spawning site for the endangered Nassau grouper (Epinephelus striatus) is located at the northeastern end of the atoll. It has been identified as one of only two viable sites remaining for the species, of nine originally known locations. In 2002, it was declared a special marine reserve, permanently closed to fishing.

The Glover's Reef Marine Reserve was established as a national protected area in 1993 under the Fisheries Act, and is managed under the Fisheries Department of the Ministry of Agriculture and Fisheries. The reserve encompasses the marine area of the atoll, totaling approximately 86,653 acres (35,067 ha). According to the World Wildlife Fund (WWF), it is considered one of the highest priority areas in the Mesoamerican reef system, providing nursery and feeding areas and a unique habitat for lobster, conch and finfish. In 1996, it was designated by UNESCO as one of seven protected areas that together form the Belize Barrier Reef Reserve System (a World Heritage-listed site).

The marine reserve is currently divided into four different management zones, with each zone having strict regulations defining activities that are permitted and prohibited.

A fifth zone has recently been created to offer greater protection to the northeast spawning aggregation site. It largely overlaps with the Seasonal Closure Zone. It is permanently closed to all fishing.
