The area was originally set aside for fruit and wood production, but only 10% was exploited.

The remainder is in excellent condition and provides a safe haven for many species typical of the Atlantic Forest of Rio de Janeiro.

[1] The conservation unit is in the Central Rio de Janeiro Atlantic Forest Mosaic, created in 2006.

The objectives are to preserve the remnants of Atlantic Forest in the Serra do Mar corridor, maintain biological diversity and provide a refuge for endangered species of flora and fauna.

The reserve may only be visited for educational purposes or for research, subject to prior approval.
