[1][2][3] The largest mangrove wetland on Trinidad is the Nariva Swamp, a permanent brackish lagoon, on the east coast.

[3] The ecoregion surrounding the mangroves on the inland side is Trinidad and Tobago moist forests, except for the Caroni Swamp, which is surrounded by a thin band of Trinidad and Tobago dry forests.

This climate is characterized as hot, humid, and having at least 60 mm of precipitation every month.

[3][4] The most common mangrove tree species is red mangrove (Rhizophora mangle), which can reach 17 meters in height and is typically found along the margins of channels with other Rhizophora species.

Black mangrove (Avicennia germinans) generally grow in stands by themselves and may reach 23 meters in height.
