The Ramsar Site consists of a lagoon complex and palustrine ecosystem distinctive of the very humid tropical ecoregion and characterized by its high biodiversity and support to endangered species such as the Lapa Verde (Ara ambigua), vulnerable species such as the Manatí (Trichechus manatus) and other important species such as the Jaguar (Panthera onca) and Pez Gaspars (Atractosteus tropicus).
