Coverage and Distribution of the Mangrove Species in the Térraba-Sierpe National Wetland, Costa Rica

The Terraba-Sierpe National Wetland is located in southeastern Costa Rica, has an approximate extension of 14 800 ha of mangrove and for this work a spectral classification with a satellite image Rapid Eye of the year 2012 was carried out to determine the distribution of the more abundant mangrove species: Rhizophora racemosa, Pelliciera rhizophorae, association between the species R. racemosa and P. rhizophorae, and Rhizophora mangle; in addition to other present wetland species as Acrostichum aureum. Also, an analysis of the geomorphological and ecological characteristics favoring the dominant species in the HNTS was accomplished and how the changes in the land use in the adjacent zones to this protected wild area generate alterations in this delicate ecosystem of great international importance.
