The structural analysis was based on the physiognomical characterization of each location, in which 12 points selected at random were taken at a distance of 20 m at least between them. In each point was applied the central quadrant point technique , in which species with a tree life form with a BHD over 10 cm were taken as a reference; in each site two parallel perpendicular lines that form quadrants were drawn, and in each of them the distance to the closest tree to the central point were measured, and the name of the species, height and BHD were recorded.
El análisis estructural se basó en la caracterización fisonómica de las localidades, en donde se tomaron 12 puntos seleccionados al azar, distanciados entre sí por lo menos 20 m. En cada punto se aplicó la técnica de Punto Cuadrante Centrado , en el cual se toman como referencia especies con forma de vida arbórea, con DAP diámetro a la altura del pecho, 130 cm mayor a 10 cm; por sitio se trazan dos líneas perpendiculares que forman cuadrantes, dentro de cada uno se mide la distancia al árbol más cercano al punto central, y se registra el nombre de la especie, su altura y su DAP.
