Diversity of urban trees in the city of Villahermosa, Tabasco, Mexico

The city of Villahermosa, Tabasco, has lost many trees so it is necessary to investigate and catalog the diversity of the vegetation through the collection of data on the species of urban trees present. For this reason, information and knowledge about the floristic richness must be updated by contributing with updated floristic lists of the urban flora of the city. The diversity of the urban tree flora of the city of Villahermosa was determined through the identification of urban tree species found along 16 road walkways within the city. With the information collected, an inventory of trees was made, a floristic list was drawn up and the ecological indices of biodiversity of Margalef, Shannon-Weaver and Simpson were determined. Additionally, the technical sheets of the species were built. In this study, a total of 5,936 trees, belonging to 60 species, distributed in 25 families, were counted. The city has a high biodiversity of tree species, pointing to it being a healthy and prosperous ecosystem; inverted Simpson dominance index (0.8985), there is no dominance by any species over the others, which will allow the trees not to fall into a homogeneous state of diversity over the years.
