Serra Negra Biological Reserve (Portuguese: Reserva Biológica de Serra Negra) is a Biological reserve in the state of Pernambuco, Brazil.

History

Indigenous languages such as Huamoé were spoken in the Serra Negra.

The reserve of 624 hectares (1,540 acres) was created on 20 September 1982. The area at time of creation was 1,100 hectares (2,700 acres). It became part of the Caatinga Ecological Corridor, created in May 2006.

The reserve is in parts of the municipalities of Floresta, Inajá and Tacaratu in Pernambuco. It is administered by the Chico Mendes Institute for Biodiversity Conservation. Today, the purpose of the reserve is to fully preserve the biota without direct human interference other than actions to restore and preserve the natural balance, biological diversity and natural ecological processes.
