Serra do Divisor NP

The Serra do Divisor National Park is a 8,463 km2 (3,268 sq mi) national park on the westernmost point of Brazil, in the state of Acre, near the Peruvian border. It also has the highest point in that state, reaching 609 meters above sea level. It has been nominated by the Brazilian government as a Tentative World Heritage Site since 1998.

 

The park is bounded to the west by the border with Peru, which runs along the Serra Divisor mountain range. It adjoins the Alto Juruá Extractive Reserve along its southeast border. The Juruá River defines the eastern boundary of the southern section of the park. The Azul River defines the eastern boundary of the northern section. The conservation unit would be included in the proposed Western Amazon Ecological Corridor.

 

Main access is by boat, on the Moa or Jurua rivers, from the City of Cruzeiro do Sul.

​

The Serra do Divisor National Park was created by decree 97.839 on 16 June 1989 to protect and preserve sample of ecosystems, ensure preservation of its natural resources, and allow controlled use by the public, education and scientific research.

 

Rapid Ecological Assessment allowed to count in one month: 43 large mammal species, more than 100 amphibian and 30 reptile species, 485 bird species, 6 families, 33 genres and 55 species of bats, 21 genres and 64 species of Hymenopteres, and finally: 29 spider families (in the northern sector of the park, only). Of these, 17 mammals, 4 reptiles and 20 birds are considered to be threatened or rare species. A new bird species was discovered, Acre Antshrike (Thamnophilus divisorius). It is known from a single small ridge (though is expected that it is presente on other, unexplored ridges in the Acre Arch uplands), and is common in the interior of shrubby woodlands on poor soil physiognomicalli similar to whote-sand habitats in the Guianas and Amazonia.
