Vast swaths of this landscape’s intact tropical forests include more than 8,000 square miles of seasonally flooded forests. This dynamic ecosystem creates habitats for a great variety of wildlife, such as freshwater dolphins, river otters, monkeys, waterbirds, fish, frogs, turtles, caimans, snakes, and many other species.

Fast Facts

  • The Piagaçu-Purus landscape covers 3,900 square miles of white- and black-water flooded forests and dry upland forest.
  • The Purus River is a tributary of the Amazon; its drainage basin covers nearly 25,000 square miles.

Challenges

This flooded forest landscape lies near Manaus, capital of the state of Amazonas. As a result, it faces increasing pressure from fishing, hunting, logging, and other human activities. The river’s large fish populations and caiman- and turtle-hatching sites attract illegal exploitation of wildlife for commercial sale. Reconstruction of the Manaus-Porto Velho highway will make it easier for outsiders to illegally access the Piagaçu-Purus reserve.

WCS Responds

With support from WCS, scientists and technicians conducted an expedition in 2001 to the lower Purus River to document the region’s biodiversity and assess  the socio-economic situation  of the local people. As a result of this work, the state of Amazonas created the Piagaçu-Purus Sustainable Development Reserve in 2003. In July 2009, WCS scientists and their partners announced the discovery of Mura's saddleback tamarin in this region. This small monkey was named after the Mura Indians, the Amerindian ethnic group that lives in the Purus and Madeira river basins where the primate occurs.

WCS conservationists are surveying the areas along highway BR 319 to estimate the numbers of medium and large mammals and the natural fluctuations of their populations. We continue to work with the Instituto Piagaçu, providing technical and financial resources to ensure that Piagaçu-Purus remains a haven for wildlife and a source of valuable natural resources for local communities.
