Abstract

Diversity and conservation status of mangrove communities in two areas of Mesocaribea biogeographic region.

Abstract

The study of mangrove communities (Avicennia germinans, Conocarpus erectus, Laguncularia racemosa and Rhyzophora mangle) in Central America reveals a total diversity of 121 species included in 7 plant communities, of which 15 are characteristic of mangroves and 31 of flooded areas with less pronounced salinity, while 75 are invasive species belonging to neighbouring communities. Frequent fires in the dry forest have caused intense erosion, leading to the silting of the lake basin. As a result, the first belt of Rhizophora vegetation is extremely rare. In contrast, there is a predominance of Laguncularia and Conocarpus mangrove plants, in addition to a belt of Phragmito Magnocaricetea with a high incidence of Phragmites australis, which acts as an indicator of sediment silting due to its shallowness.
