Water is vital to maintain ecosystems and riparian vegetation is critical and important in the regulation of biological and biogeochemical cycles and the object of this is one of the headwaters of the Alto River São Lourenco Campo Verde/MT, with the aim of assessing the degree of regeneration vegetable environment using different technologies associated with the nucleation muvuca seed, adding green manure. The study area was divided to receive five treatments, each with a technique of planting different. In the treatments, except the first which was kept isolated, there was in each random selection of three installments, measuring 81m2 , totaling 12 plots. Was performed to identify and count species, measurement of soil cover, richness, abundance and density of species, monitoring illustrative vegetable production profile tiered canopy treatments, biomarkers recovery of degraded areas and listing of aggressive invasive species found in collection sites. We identified twenty five species of forty-five plants planted. After the period of sampling, the soil is almost completely covered by vegetation and there was a return of wildlife. The most successful techniques were implemented in treatment 3, the muvuca seed planter with vacuum and seedlings spaced at 5 x 5 meters, the site recovered well, with high species richness and abundance, and showed little spacing between the species and forming microclimate, providing numerous advantages to the environment. The use of techniques associated with nucleation muvuca seed, after two years of implementation have proven efficient in the recovery of degraded environments, as a method of propulsion natural succession, and low cost.
