Abstract


This paper is a review of the endemic and threatened plant species of El Triunfo Biosphere Reserve. From a floristic inventory that includes 2,990 species and 12,835 herbarium records, we reviewed the presence of each species in the official listings of the Mexican Norm (NOM-059-SEMARNAT-2010) and Red List of International Union for Conservation of Nature, determined its level of endemism with support of a database. We obtained a checklist of 347 endemic species: 5.9% are endemic to the El Triunfo Reserve, 23.9% to Chiapas and 27.6% to Chiapas and Guatemala. We found 244 species at risk, for Mexican Norm status are: 28 to be protected, 36 threatened, and 11 endangered. For International Union for Conservation of Nature Red List categories are: 16 critically endangered, 63 endangered, 74 vulnerable, and 29 near threatened. The number of species endemics and threatened represent 17% of the estimated flora for El Triunfo Reserve and 4.2% of the flora of Chiapas. The cloud forest ecosystem presented the highest number of threatened and endemic species. The El Triunfo Reserve is located in a floristically diverse geographic region and protects a significant number of plant species both endemic and threatened.
