البرتغالية. This study was conducted at Jamanchim Farm and aimed to evaluate the natural regeneration in an area of forest in the northern region of Mato Grosso state. We evaluated the horizontal structure of phytosociological parameters (density, frequency, dominance, importance value index, diversity index and natural regeneration). For the evaluation of the parameters were set six plots of 10 x 10m in areas of glades located within the permanent plots of the management plan, which was explored in 2007. We sampled all individuals taller than 10 cm. Diameter were measured for analysis subjects with a diameter of 30 cm of soil (DAS 30) ≥ 1 cm, and identified 23 families, 25 genera and 15 species, in a total of 810 individuals at 0,6 hectare. As families most representative with respect to number of individuals were Euphorbiaceae (188), Burseraceae (159), Moraceae (81), Myrtaceae (65), Lauraceae (61), Mimosaceae (39). The analysis of datas indicated a general survey of the Shannon-Wienner of 2,57 for class I and II and 2.21 for class III. The most important species were Crotonu rucurana and Trattinickia rhoifolia, these two species are featured in all parameters evaluated. Based on the work it is clear that the forest in question had low floristic diversity.
