description In the northeastern region of Mexico, there is an increase in the establishment of grasslands for livestock, which has created changes in the structure and floristic diversity of ecosystem. The aim of this study was to determine the structure and diversity of the woody species vegetation of an area of Tamaulipas thorn-scrub (MET) which was modified for livestock rising in Nuevo Leon, Mexico, to establish whether or not the changes have contributed to the conservation of plant diversity. The livestock activity practiced in the researched area is mixed purpose use at a moderate intensity, with a thinning treatment at the lower vegetation layer (d ˂ 5 cm) to create open areas for cattle grazing in the study area. Four sampling plots of 1 600 m2 each were selected. Dasometric measures were recorded and ecological indexes were estimated. The results are a record of 8 families, 16 genus and 17 species of trees and shrubs. The absolute density was 309/ha, while the estimated canopy area was 9 521.83 m2/ha. Richness (Da = 3.03) and species diversity (H’ = 2.31) resulted in similar values to scrubs with nonproductive activity. Species with the greatest IVI are characteristic of the MET: Prosopis laevigata (IVI = 28.59), Havardia pallens (IVI = 13.41) and Cordia boissieri (IVI = 8.89), from which, Prosopis laevigata is considered as a species for forage use. We conclude that the composition of the tree and shrub species in this livestock rising system contributes to preserving the desirable attributes of the native vegetation communities, such as richness and species diversity, density and canopy area.

El objetivo de la presente investigación fue determinar algunos parámetros dasométricos y de diversidad de los elementos leñosos presentes en un área de matorral espinoso tamaulipeco (MET), con actividad pecuaria, en el estado de Nuevo León, México, para establecer si las modificaciones realizadas contribuyen o no a la conservación de la diversidad vegetal. La actividad pecuaria que se realizaba en el área de estudio era un aprovechamiento mixto de moderada intensidad, con aclareos por lo bajo (d ˂ 5 cm). Se seleccionaron cuatro sitios de muestreo de 1 600 m2 cada uno. Se recolectaron datos sobre variables dasométricas y se obtuvieron índices ecológicos. Los resultados permitieron un registro de 8 familias, 16 géneros y 17 especies arbóreas y arbustivas. La densidad absoluta reportada fue de 309 individuos/ha, mientras que el área de copa estimada fue de 9 521.83 m2 /ha. La riqueza (Da = 3.03) y diversidad (H´ = 2.31) específicas, resultaron en valores similares a matorrales sin actividad productiva. Las especies con mayor importancia dentro del área de estudio fueron características del MET: Prosopis laevigata (IVI = 28.59), Havardia pallens (IVI = 13.41) y Cordia boissieri (IVI = 8.89), de las cuales, Prosopis laevigata tiene antecedentes de uso forrajero. Se concluye que la composición de especies arbóreas y arbustivas en este sistema pecuario conserva atributos deseables de las comunidades vegetales nativas, como la riqueza de especies, diversidad, densidad y área de copa.   Universidad Autónoma de Tamaulipas 2019-07-29 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion application/pdf text/html application/xml https://revistaciencia.uat.edu.mx/index.php/CienciaUAT/article/view/1001 10.29059/cienciauat.v14i1.1001 CienciaUAT; Vol 14 No. 1.
