History

The reserve is in area where there has been intense pressure on the land from speculators and squatters. The Juatinga Ecological Reserve was created by state decree 17.981 of 30 October 1992. It is home to about 400 families, or 2,000 people, living in basic conditions in small coastal villages. It was created to promote the caiçaras culture of the residents of the reserve, reconciling their life style with conservation of the environment.

. Vegetation is mainly dense rainforest. Some areas contain vegetation in different stages of succession, including agricultural fields, scrub and secondary growth. A 2014 study of the ''Laranjeiras-Praia do Sono'' and ''Praia do Sono-Praia de Antigos'' trails in the south of the reserve found that one of the trails was somewhat degraded, and had ravine erosions in several places. The primary rainforest at higher elevations protects threatened species such as the southern muriqui (''Brachyteles arachnoides'') and the
