Overview

The Rio Negro is the biggest tributary river on the north side of the Amazon basin. At over 1,500 kilometres long, it is the longest blackwater river in the world, and it supports one of the largest preserved tropical rainforests. The Ramsar Site covers over 12 million hectares; it includes a variety of wetlands that are particular to the region, such as Igapó (blackwater-flooded) forests, edaphic savannas and fluvial archipelagos, and comprises more than 20 conservation units. The designation of the Site greatly increases the connectivity of Brazil’s protected areas. Its rich biodiversity includes globally-threatened bird species such as the ash-breasted antbird Myrmoborus lugubris, and plants such as the Brazil nut Bertholletia excelsa. Three endangered mammals are present: the giant river otter (Pteronura brasiliensis), the Brazilian bare-faced tamarin (Saguinus bicolor) and the white-bellied spider monkey (Ateles belzebuth). The Site also contributes to the Amazon rainforest’s climate regulation on which the stability of the planet depends. The local communities are enormously ethnically and culturally diverse; the protected areas included in the Site aim to support their low-impact sustainable forms of resource utilization and agriculture. The Site directly or indirectly supplies water to at least six Brazilian municipalities, and the main river channel serves as a waterway connecting communities. Among the main threats to the Site are land conversion and clearance of vegetation, as well as hunting and fishing.
