Abstract
The present research was aimed at determining the forest cover in ten farms with traditional agroforestry systems, "based on the characterization of each of them (farms)", carried out by Moreno et al. (2013). A planimetric survey and zoning of the agricultural areas with vegetation cover was carried out, where the common name, diameters, commercial and total height of the trees greater than 10 cm DBH of the adult stand were recorded through a census, subsequently the data were separated into diameter classes with 10 cm intervals, determining the basal area and commercial volume, for the taxonomic identification of the species the Angiosperm Phylogenetic Group (APG) classification system was used. A total of 524 forest species associated with agroforestry systems were identified and classified into four different types according to their production components. The floristic diversity corresponds to 35 species, 33 genera, and 19 families, the most abundant species was Cordia alliodora (Ruiz & Pav.) Oken, being the Boraginaceae family the most abundant, the Ecological Importance Value Index (IVI) was shown to be most representative for Ceiba pentandra (L.) Gaertn, with 77.57%; the Shannon index determined a medium diversity in SAF1, SAF2 and SAF4, unlike SAF3 that showed low diversity, within the Jaccard analysis that 0.05% was obtained, indicating that there is little similarity of species among the SAF.
