The Great Morass, a 125 sq. mile mangrove swamp, extends inland from the mouth of the Black River - Jamaica's longest river (44 miles). It is possible to navigate a boat up river for about 12 miles. This wetland is a vital preserve for more than 100 bird species, among them - Jacanas, egrets, whistling-ducks, water hen, seven species of herons and red-footed coots. The brackish waters also harbor an underwater bounty of snook, and tarpon that can reach 200 lbs. Fishermen can be seen spear fishing and checking shrimp pots from dug out canoes.
In 1995, the international environmental organization Ramsar Cites recognized The Black River Great Morass as an important nature preserve to be protected.
