The Ribeirão Grande watershed is composed of first, second, and third-order streams. The vegetation is in an intermediate stage of conservation because of anthropogenic impact, e.g., deforestation watershed. The streams have riparian vegetation composed of secondary forest and introduced species; thus, the tree cover shows a sparse canopy, and the streams receive greater solar insolation. The surrounding area is characterized by traditional families who explore the preserved area by developing subsistence agriculture (

The main environmental impacts that can interfere with the local biodiversity of the Cachoeira Grande watershed are related to the urban occupation around the MNLP. On the other hand, around the main rivers and streams of the Ribeirão Grande watershed, there is a development of subsistence agriculture by traditional families (that already occupied the area before the implementation of the UC) with small plantations of banana, beans, cassava, corn, and others, plus small livestock (
