It covered a large, mountainous region that included untouched Atlantic Forest and land occupied by traditional communities.

[5] Law 10.850 of 6 July 2001 altered the boundaries of the Jacupiranga State Park to exclude the quilombola communities of Nhunguara, Sapatu and André Lopes, and the Intervales State Park to exclude the quilombola communities of Pilões, Maria Rosa, São Pedro, Ivaporunduva and Pedro Cubas.

A working group was then formed with representatives of government and non-government bodies, chaired by the president of the Atlantic Forest Biosphere Reserve, which presented its recommendations to the Legislative Assembly of the State of São Paulo in June 2007.

[5] The quilombola communities that had formerly been in the state park, and then in the Serra do Mar APA were made part of the Quilombos do Médio Ribeira Environmental Protection Area.
