The environmental benefits arising from the interaction between matter and energy flows of permacultural systems accelerate the recovery processes of degraded areas, which can be potentiated by the increase of plant biomass associated with the green manure technique, proposed in this work for the study territory: the surroundings of two Conservation Units (UC), of the Private Reserve of Natural Heritage (RPPN) type, the RPPN Águas Claras I and II. The RPPN Águas Claras I and II are located in the Macabu River basin, a microbasin of the Carukango River. The objective of this study was to analyze areas submitted to reforestation and agroforestry system (SAF) projects, through estimates of local biomass obtained with the aid of secondary data from the UCs’ forest inventory. As a result, it was possible to list Ficus sp and Sparattosperma leucanthum as priority native species for forest restoration. It was concluded that it is necessary to consort the two species with the planting of species considered green manures, in order to increase forest biomass and stimulate the improvement of soil conditions in the degraded portion of the reserve. This strategy can accelerate the regeneration process, as indicated by secondary soil analysis data using scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDS), performed in the area of implementation of the SAF.
