JUAREZ-FRAGOSO, Mauricio Arturo; LOPEZ-ACOSTA, Juan Carlos  e  VEZLAZQUEZ-ROSAS, Noé. Contribution to the ecological and floristic knowledge of the pametto woodland dominated by Sabal mexicana Mart. To southeast Veracruz, México. Polibotánica [online]. 2017, n.44, pp.51-66. ISSN 1405-2768.  https://doi.org/10.18387/polibotanica.44.4.

We presented a characterization of flora from the palmetto woodland dominated by Sabal mexicana, with distribution to southeast Mexico. This area has usually been considered a primary palmetto woodland, but highly impacted by anthropogenic factors. Although it is a threatened formation, basic information on its plant biodiversity is scant. We made a systematic sampling, covering a total of 6 000 m2 by 60 plots (10 x 10 meach one) distributed in the different stages of the area. In addition we made free collections of the most conspicuous and representative species. For each species recorded we made a literature search of their life history, dispersal type, strategy development and conservation status according to NOM-059-ECOL-2010. We recorded 122 species in total (84 genera and 44 families). The best represented families were Fabaceae (11 spp.), Moraceae (10 spp.) and Asteraceae (7 spp.); the genera were Ficus (5 spp.) and Smilax (4 spp). More than 11 species were collected outside the plots mainly Cactaceae. The life form more representative were trees, heliophytes, perennial species and zoochory dispersión. This study contributes knowledge of environments commonly referred to as "altered". In this palm woodland is important to understand the composition and dynamics to establish strategies for biodiversity conservation and environmental services.
