Potential areas for conservation of useful flora of the Tehuacán-Cuicatlán Valley, Mexico

In the Tehuacán-Cuicatlán Valley (TCV) a total of 1605 useful plant species have been recorded. All of them, anthropologically speaking, are very important and thus, it is worthy to explore various options for ensuring their conservation. Accordingly, the aim of this work was focused in identifying...

Summary:In the Tehuacán-Cuicatlán Valley (TCV) a total of 1605 useful plant species have been recorded. All of them, anthropologically speaking, are very important and thus, it is worthy to explore various options for ensuring their conservation. Accordingly, the aim of this work was focused in identifying potential areas for the conservation of useful plant species of the TCV. For doing so, we compared two databases from the TCV. The known and potential distributions were identified for 272 species, using MaxEnt. The distribution data was intersected with a grid of 153 operative geographic units (OGUs) that were used to elaborate the species presence matrixes. An optimization algorithm was applied for both the known and the potential distribution and their respective species accumulation curves were compared. A list of 583 useful plant species of the TCV was obtained. These species are heterogeneously distributed in 111 of the 153 recorded OGUs. Ten families contribute with 55.06% of the overall plant richness of the TCV. In addition, the analysis revealed that at least, 13 OGUs are needed to conserve 81% of the useful flora, which represents approximately 30% of the flora, in only 8.5% of the total TCV surface. The selected sites coincide with those areas where some incipient domestication processes, as well as, plant endemism and richness centers have been reported.
