Ilha de Peruíbe

Ilha de Peruíbe is part of the Tupiniquins Ecological Station, a coastal marine area of 1,728 hectares created on 21 July 1986. With no beach and no conditions for boats to dock at the island, it rises 58 m high, is covered by dense Atlantic Forest shrub vegetation and grassland, and is surrounded by a rocky shore. Boats use the area next to the island to shelter from bad weather and to anchor while waiting for the right tide to enter the mouth of the Peruíbe River.

Since the 1970s, works at the mouth of the Guaraú River, including shifting the river mouth and building a jetty, have increased the suspended material in the water near the island. A layer of fine sediment covers much of the rocky bottoms around the island, including the algae and invertebrates. Above the water, kelp gulls (Larus dominicanus) build their nests on the island.
