The methodology used was to divide the area in 2 lots, within which were stablished 20 Sampling Units, dimensions of 20 x 20 m (400 m2) in they mass adult was evaluated (DBH> 7.5 cm.) for the evaluation of natural regeneration subunits sampling 10 x 10 m were established. with (DBH> 2.5 cm and <7.5 cm) and subunits of 2 x 2 m. with (DBH <2.5 cm.). The parameters taken were: total and commercial, DAP, height and crown diameter. To determine the degree of conservation of native species a diagnosis using surveys to residents of surrounding areas to the farm with questions based on criteria of conservation and land degradation was performed, the data obtained were tabulated and the results were: in the case natural regeneration 28 families, 40 genera, 43 species and 191 individuals, and in the case of the subplots (DAP <2.5 cm) 28 families, 39 gender, 41 species and 320 individuals were found. Most family, genus, species and individual registered in lot 2. The most important families by the number of species were Fabaceae with 5 species, Boraginaceae 4, Moraceae 3 and the remainder recorded 2 and a species. Regarding the Shannon Diversity Index, there is similarity in both lots classified as medium diversity. The species with the highest IVI was Pythecellobiun (Guasmo) with 28.41%. In the vertical structure of the altitude from 7 - 14 meters have as many individuals in the two batches. Most found height is 25 meters and the species that reach this stage are: Triplaris cunmingiana, Leucaena trichodes and Sassafras albidum. |
