by doing so, the municipality is trying to further protect the rainforest from excessive tourism, uncontrolled urban development, and other issues that would endanger the rich ecosystem.

among the many protected species that live in the forest, are the red topped amazon parrot (amazona rhodocorytha), the red-ruffed fruit crow (pyroderus scutatus), the maned sloth (bradypus torquatus), and the brown howler monkey (alouatta guariba) - further, inclusion in the unesco's list would help limit the commercial maritime activities that could destroy the coral reef of the region.

supervised by the fundação instituto estadual de florestas - ief, the parque estadual da ilha grande  was created in 1971, with the objective of preserving the area's rainforest and biodiversity.
