The studies were carried out from May to November 2015 at an altitude of 1 680-2 000 m, and. For removal of information, five temporary plots of 20 mx 20 m (400 m2) were instaled for trees greater than or equal to 5 cm D1,30 m, inside of them three subplots of 5 mx 5 m (25 m2) were delimited for bushes and five subpilots of 1 mx 1 m (1 m2) for herbs. To calculate the floristic composition, ecological parameters were calculated: Absoluty density (D), relative density (DR), relative dominance (DMR), relative frequency (FR) and index importance value (IVI): structural profiles was performed through a transect of 10 x 50 m, where the trees equal or older than 5 cm D1,30 m were registred in distances X and Y. 52 families, 81 genera, 36 species and 64 morphospecies were registred, they were distributed in 20 species and 39 tree morphospecies, 9 species and 15 shrubby morphospecies 7 and species and 10 herbaceous morphospecies. The most diverse families in the tree layer are: Rubiaceae , Lauraceae , Clusiaceae , Euphorbiaceae and Melastomataceae ; in the shrub layer : Piperaceae , Solanaceae and Poaceae ; and in the herbaceous layer : Dryopteridaceae , Polypodiaceae and Araceae . Most ecologically important species include Alsophila cuspidata and Nectandra lineatifolia in the tree layer; Chamaedorea linearis and Philodendron sp. in stratum shrub and Elaphoglossum sp.2. and Peperomia sp. in the herbaceous layer . Most natural regeneration is contained in the category seedlings with 48.51 %, followed by the brinzal category with 42.45% , the category latizal low with 7.76 % and finally the high category with 1,28 latizal % |
