A flower list was made after species identification, then the alpha (α) diversity indicators were calculated (Species abundance (S), Dominance (Simpson D), and General Diversity (Shannon, H). The indicators for the beta diversity were Jaccard (Ij), Morisita-Horn (IM-H), and Ecological Subordination (ES). The data collected included 62 509 individuals from 65 families, 154 genders, and 183 species. For both groups, the alpha indicators showed an increasing trend between periods, with values ranging within the parameters for each indicator. La Caballería farm was the exception, where the Shannon diversity index (H) was not within the set range for proper diversity and abundance during the dry season. The beta diversity indicators showed differing values among the samples studied, which prove the existence of specific species adapted to the environmental conditions of the place. 1 Forestry Eng.
