The Rio Negro State Park South Section is in the central Amazonia corridor, in the Lower Rio Negro Mosaic. It protects part of the basin of the Cuieiras river. The river and the Araras and Jaraqui streams, tributaries of the Rio Negro, are low-lying and have flooded mouths. The main plant formations are Igapó forest, dense terra firma forest and Campinarana. Wildlife is very diverse. It includes the pied tamarin, an endemic primate, in the south of the park and the red-handed tamarin on the right bank of the Cuieiras.
History
The two sections of the Rio Negro State Park were created by state governorAmazonino Mendes by decree 16.497 of 2 April 1995 with the stated purpose of preserving its natural ecosystems without alteration and supporting scientific, cultural, educational and recreational activities. Tourism was clearly the primary purpose. The state park had a total area of of which the north section had an area of and the south section had an area of. Law 2646 of 22 May 2001, also signed by governor Amazonino Mendes, reduced the areas of both sections. The north section now had and the south had. The original sections had both extended along both banks of the Rio Negro. With the revised boundaries the north section was reduced to a smaller part of the right bank of the Rio Negro, although it now extended further to west, and the south section was reduced to a smaller part of the left bank of the river. It became part of the Central Amazon Ecological Corridor, established in 2002. The park is administered by the Centro Estadual de Unidades de Conservação do Amazonas. The consultative council for the south section was created on 22 November 2010. The conservation unit is supported by the Amazon Region Protected Areas Program. When the state park was created the existing population of indigenous and non-indigenous people was not taken into account. A long campaign for regularisation of property rights began. On 28 December 2010 a law was passed to allow the lands occupied by traditional populations in the park to become a sustainable development reserve. On 24 March 2014 a law created the Puranga Conquista Sustainable Development Reserve and changed the limits of the Rio Negro State Park South Section and the Aturiá-Apuauzinho section of the Margem Esquerda do Rio Negro Environmental Protection Area. The area of the state park was reduced to.
