A very large mosaic of ecosystems formed basically of recent alluvial plains, rivers, lakes, and marshes. Located in a transition zone, the site presents unique characteristics in terms of ecosystem formation processes and vegetal succession. It is estimated that the site supports more than 50,000 waterbirds; some 13 migratory species visit, and the site hosts more than 1% of the global population of the Cattle Egret Bubulcus ibis. The fish community of the Marmoré river basin numbers 394 species, representing 55% of the fish species in the Amazon basin, and the site hosts more than 1% of the global population of the Bolivian river dolphin Inia boliviensis.
