Their importance is often unrecognized. These are the Caroni Swamp in Trinidad and Bon Accord Lagoon in Tobago. Nariva Swamp, a largely freshwater system, with herbaceous species, is another type of wetland found in Trinidad. Wetlands play a pivotal role in the environmental dynamics of the coastlines of our country. Unfortunately, demands of development often override the need for conservation and many of these wetlands are in danger of being degraded or destroyed.
Wetlands serve vital environmental functions.
They function as aquatic breeding grounds and nurseries for salt and freshwater organisms, especially several species of commercially important fish. Mangroves provide essential nutrients for juveniles as well as protection during the critical stage of their development. It is estimated that two-thirds of the commercial fish caught in Trinidad and Tobago inhabited mangroves during some stage of their development. Wetlands provide habitat for different species of wildlife. The Caroni Swamp has well over 160 species of birds, including our national bird, the scarlet ibis.
