The Despraiado Sustainable Development Reserve is divided between the municipalities of Iguape (95.36%), Miracatu (1.01%) and Pedro de Toledo (3.6%) in the state of São Paulo.

It included the Juréia-Itatins Ecological Station and the newly created Itinguçu and Prelado state parks, Despraiado and Barra do Una sustainable development reserves and the Ilhas do Abrigo e Guararitama Wildlife Refuge.

[3] The state parks and sustainable development reserves were carved out of the ecological station.

[6] Law 14.982 of 8 April 2013 again altered the limits of the Juréia-Itatins Ecological Station, re-categorising some areas.

The law recreated the Jureia-Itatins Mosaic, this time covering 97,213 hectares (240,220 acres).
