This Ramsar Site is located in the Orinoco – Amazon transition zone. It comprises the confluence zones of the rivers Inírida- Guaviare, Guaviare-Atabapo and Guaviare-Ventuari which join the Orinoco River. This is a unique area as its flooded forests belong to the Amazon biome while its ‘whitewater’, ‘blackwater’ and ‘clearwater’ hydrological ecosystems are characteristic of the Orinoco River. Because of its unique location, the Site supports numerous species. Among these are threatened or endangered species such as the military macaw (Ara militaris), the giant otter (Pteronura brasiliensis) and the giant anteater (Myrmecophaga tridactyla) as well as endemic species of the Orinoco basin such as Sorubim lima, Pseudoplatystoma metaense and P. orinocoense among others. It is also supports 476 fish species (50% of the fish species of the Orinoco Basin and 34% of the country’s species), 200 species of mammals, 903 of plants and 324 species of birds. The Site also has important cultural values for the indigenous communities that live there and depend on it for their livelihoods. The threats to the Site include gold mining and the increase in the extent of land used for agriculture.
