The Great Morass in Negril is a vast and ecologically vital wetland that covers thousands of hectares in the parishes of Westmoreland and Hanover. As Jamaica's largest freshwater wetland, it acts as a massive natural filter, purifying groundwater before it reaches the delicate coral reefs of the Negril Marine Park and the famous Seven Mile Beach. The landscape is a complex mosaic of sawgrass marshes, peat bogs, and dense mangrove forests. It is home to the island's largest stand of the endemic Royal Palm (Roystonea princeps) and provides a sanctuary for a wealth of wildlife, including the American crocodile and over 100 bird species. Efforts to preserve this fragile ecosystem are crucial, as it serves as a significant carbon sink and a buffer against storm surges. Visitors can explore this mystical environment at the Royal Palm Reserve, which features boardwalks through the heart of the swamp.
