We characterized the vegetation structure and the floristic composition of the semi evergreen tropical forest in the locality of Bethania, Campeche, México. We marked ten 10 m x 10 m (1 000 m2) plots, where all individuals with a diameter at breast height (DBH) of ≥ 2 cm were measured. The structural analysis of the vegetation is based on the species importance values (IV). We found 490 woody individuals belonging to 34 species, grouped into 33 genera and 23 families. The Fabaceae was the plant family with more species (7). Terminalia buceras was the species with the highest relative dominance, followed by Metopium brownei, Coccoloba barbadensis and Zygia sp. These four species accounted for almost half (43.5%) of the relative importance value. Our results indicate that the medium semievergreen forest is characterized by floristic elements subtect to flooding. The number of woody individuals is concentrated in three families (Fabaceae, Ochnaceae and Polygonaceae). Finally, Bravaisia berlandieriana form a competitive hierarchy in the shrub layer that colonizes clearings of semi evergreen tropical forest of the locality of Bethania.References
