The objective of this work was to study the use and occupation of the lands of the Cavalos Stream (BHCC) and São Floriano Stream (BHCSF) watersheds, as well as to suggest suggestions for local improvements. The procedures were performed in the ArcMap program, using GEOBASES/ES as a cartographic base. The basins were delimited, initially generating the Digital Elevation Model, obtaining the local hydrographic network. In GEOBASES/ES, they were acquired in two land use files (shp) for the state of Espírito Santo in the mappings of the years 2007-2008 and 2012-2015, to later define the Areas of Permanent Preservation (PPA) and study of these basins according to the literature. There is a greater predominance of native vegetation, which presented a reduction in BHCC, being a worrying factor. Temporal crops presented good representativeness and the macega presented growth, constituting a problem in the land use management. The silviculture (eucalyptus; pinus) presented growth, even in PPAs, which suffered reduction of native vegetation, but presented pasture reduction. Measures such as the implementation of agroforestry systems to the detriment of monoculture, proper management of forestry, agriculture and pasture, and environmental education are fundamental. For future studies, analyze the evolution of forestry and monitor watercourses.
