2.4.1 MANGROVE ECOREGIONAL EXERCISES

A CONSERVATION ASSESMENT OF MANGROVE ECOSYSTEMS

OF LATIN AMÉRICA AND THE CARIBBEAN WWF (Olson et al. 1996)

Mangroves have received insufficient attention from conservation donors and agencies in Latin America. Perhaps the major reason that mangroves are underrepresented in conservation programs is that they are of superficially similar appearance across regions, and mangroves as a forest type, consists of only a few tree species. However a mangrove ecosystem contains a widw diversity of aquatic and marine species an can rival any habitat types in terms of species richness when both terrestrial and acuatic species are counted. More importantly, mangroves are truly keystone ecosystems because their productivity and the ecological services they provide are critical for maintaining surrounding ecosystems.
