BURGOS-HERNANDEZ, Mireya  y  CASTILLO-CAMPOS, Gonzalo. Floristic analysis of the tropical evergreen forest in the center-north of Veracruz, México. Ecosistemas y recur. agropecuarios [online]. 2018, vol.5, n.15, pp.451-463. ISSN 2007-901X.  http://dx.doi.org/10.19136/era.a5n15.1676.

The objective was to characterize and describe the floristic composition of the tropical evergreen forest in the center-north of the State of Veracruz, México. A floristic inventory was carried out by the parcel method. To identify the heterogeneity among sampling plots, a Jaccard similarity analysis and a principal component analysis (PCA) were performed. The State of conservation was analyzed with the criteria of recorded species, frequency, coverage-abundance, growth forms, vertical structure and threatened species. The floristic list ineludes 180 species, 129 genera and 74 families. Seven species were detected in the risk category and one endemic to the State. The Jaccard similarity analysis and PCA determined floristic differences among the plots sampled. The forest fragment studied is conserved and proteets a great richness of native species. The inherent characteristics of the forest, its high species richness and the presence of endemic and at-risk species, as well as the small area it occupies, indícate that measures must be established for its conservation. It is suggested that the forest remnant studied be integrated into the country’s tropical conservation strategies, based on the species richness that it safeguards.
