[1] The park is on the sea shore, isolated from the Serra do Mar, and protects biodiversity in an area that is heavily affected by housing, industry and port activities.

[1] The town of São Vicente, just north of the park, was officially founded on 22 January 1532, the first Vila in Brazil.

The tannery was closed in the 1970s, and infrastructure such as electricity, water, sewage and paved roads were gradually introduced in the communities round the park area.

Threatened species were Euterpe edulis, Tabebuia cassinoides, Protium kleinii, Swartzia flaemingii, Lobelia anceps, Ocotea odorifera, Hibiscus bifurcatus, Brosimum glaziovii and Pharus latifolius.

The survey reported Erythroxylum catharinense Amaral and Beilschmiedia fluminensis Kosterm for the first time for São Paulo State.

[10] Threats come from the population living within the park, hunting, illegal extraction of forest products, fishing, incursions by domestic animals, release of exotic animals, military activities in the area of the park that overlaps with the Itaipu fortress, and indigenous people occupying the Paranapuã beach from 2004.
