The Jaú National Park is the largest national park in Brazil and the world, in continuous and intact tropical rainforest. Located between the cities of Novo Airão and Barcelos, to the north of Amazonas, it is named after the Park’s main river, and one of the largest Brazilian fish: Jaú. Today, this ecological paradise is known as a model of the Amazon Conservation Unit, conjunctly made up of the Sustainable Development Reserves of Amanã and Mamirauá, the largest preserved biological corridor in the world in terms of equatorial jungle, with over 5.7 million hectares.
The Park preserves the largest black water basin in the world, the Rio Negro Basin. The dark color of the water comes from the springs that emerge from very ancient lands – which leaves the rivers loaded with organic and iron elements. It is relief is quite diversified, including flood areas, plains, hills, igapós, igarapés, and firm land forests. Bathed by rivers Negro, Jaú, Carabinani, Unini, Pauini and Canauaru, the Jaú Park also concentrates several waterfalls of unequaled beauty.
This region was the first colonization pole in the Amazon, made by Indians and marked by fierce battles for the dominion of the territory. There are reports of archeological finds in ceramics and stone engravings.
The Jaú National Park is not yet prepared for ample tourist visits. Usually, it receives the visits of researchers, who stay in Ibama accommodations prepared to receive 8 people at most. To book visits, it is necessary to previously contact the Ibama post in the park, with at least a month’s advance, by phone: + 55 (92) 613-3277, extension 229. Tourist visits to river Carabinani also only occur in small scale. The period is ideal for visits between July and November. The park stays open daily from 7 AM to 6 PM.
Flora and Fauna
Botanical studies developed in the Park have already catalogued about 400 plant species. Many of them are restricted to determined environments found only in the Jaú Park, such as igapó (submerged forests) and firm land forests.
The park also accommodates a rich fauna – comparable to various Conservation Units of the Amazon. So far, 263 fish species have been catalogued within the boundaries of the Jaú National Park, some of them only just discovered by science. Thus number represents a major part of the fauna described in the River Negro basin – about 500 species -, reinforcing the park’s need to stay under protection.
