RESUMO:

The present work was structured in two chapters, the first one addressing the main forest species selected for planting in projects for the recovery of springs and degraded areas in the Rondoniense forest zone, the second chapter deals with the evaluation of quality indicators in an area in the process of recovery in the Igarapé D'Alincourt microbasin. Data collection was carried out in the archives of the NGO ECOPORÉ and the Secretary of State for Environmental Development (SEDAM) and within the scope of the riparian forest recovery projects of the D'Alincourt creek and the Manicoré creek. Data were organized in an electronic spreadsheet and grouped according to the succession group of each non-pioneer and pioneer species, type of seed dispersion and type of soil. In the second part, an on-site visit was made to an area located in the microbasin of the D'Alincourt creek, which is in the process of recovery. To assess the vegetation indicators in the recovered area, two blocks of spring area in the process of recovery were used, Block 1 with an area of 0.17 ha and Block 2 with 0.11ha.An inventory of the species present in the areas was carried out in two categories, adult vegetation and regeneration, with two transects of 10x10m wide and 160, 110 m in length, respectively, being installed. Adult vegetation, 185 adult individuals were measured (DBH>10cm), which represented 685.19 ind.ha-1, occupying a basal area of 4.373 m² and producing 28.7 Mg of biomass. It was possible to identify 88% of the sampled trees, of which the presence of 11 families and 20 species was verified. The Shannon index was 2.46 and as (J = 0.82). Natural regeneration was observed only in range I. 78 individuals were sampled in three seedling classes, sticks and canes, 8 with ht≥ 50cm and DBH ≤ 1 cm, 20 with DBH ≤ 5 and ≤ 1 cm and 50 with DBH ≥ 5 and ≤ 10 cm. There was a relationship between the selected species and those inventoried in block I and II, forest species are following the trend of the secondary forest model.
