History
The Gurupi Biological Reserve was created on 12 January 1988.
The reserve is administered by the Chico Mendes Institute for Biodiversity Conservation.[2]
The Biological Reserve is a "strict nature reserve" under IUCN protected area category Ia.
The purpose is full preservation of biota and other natural attributes without human intervention.
Specifically the reserve maintains a representative sample of the Amazon rainforest in Maranhão.[1]
The reserve is supported by the Amazon Region Protected Areas Program.[3]
The proposed South Amazon Ecological Corridor would link the reserve to other protected areas and indigenous territories in the region.[4]
