It provides coordinated management for a group of 10 federal, state and municipal conservation units covering an area of Atlantic Forest along the coast and up the slopes of the Bocaina plateau.

A project to create three new protected area mosaics in the Serra do Mar Ecological Corridor began in December 2005,[1] coordinated by the National Council of the Atlantic Forest Biosphere Reserve.

[5] It ranges from coastal areas through steep slopes to the top of the dissected Bocaina plateau at an altitude of 2,088 metres (6,850 ft).

[3] The Bocaina Mosaic aims to encourage integrated management of the various protected areas, contributing to the preservation and conservation of natural and fishing resources as well as sustainable development of the territory.

The mosaic has an advisory board with representation of government agencies and civil society to provide integrated management of the conservation units and their buffer zones.
