Nucleation Techniques as a Strategy for Recovery and Environmental Valuation of Degraded Areas Located in Alto Rio São Lourenço, Campo Verde-MT

Abstract

Our aim was to assess the effectiveness of different techniques that comprise the recovery plan of degraded area (RPDA) in one of the headwaters of São Lourenço River, Campo Verde-MT, by monitoring the early stage of plant regeneration of permanent preservation degraded areas, according to the Federal Law 4.771/65 and its updates. The experimental area was divided into five treatments, for the planting of native plants, fruit, legumes, green manure and muvuca seed, based on the precepts of nucleation. For each treatment there was a random selection of three installments, measuring 81m2, totaling 12 plots. The planting, the identification and the characterization of indicators of vegetation regeneration site were monitored in these plots. The indicators found at the site were: flowers, fruits and seeds of revegetated species; traces and presence of wildlife; litter production and soil cover, and formation of microclimates, with increasing relative humidity and decreased atmospheric temperature.
