| description | Background and Aims: The studies of plant communities allow to know the impacts caused by the agricultural and livestock activities, especially in arid zones. The objective of this work was to contrast the diversity, composition and structure of the arboreal and shrub strata of three areas (Agroforestry, Regenerated and Reference) of the xerophilous scrub.Methods: In each area four sampling sites of 1600 m2 each one were established randomly, where all arboreal and shrubby individuals were registered and censused. In each area, ecological parameters were calculated, as well as the Shannon and Margalef indices.Key results: In the three areas, a total of 25 species of vascular plants belonging to 22 genera and 15 families were registered. The best represented family was Fabaceae with nine species, being the genus Acacia the one that presented the largest species number (three). The observed values of species richness, the Shannon index, Margalef index and abundance between the Reference and Agroforestry area were similar, and both were significantly higher than the values of the Regenerated area. The Agroforestry area presented lower abundance but greater dominance compared with the other two areas studied, and it was the area that reached the highest percentage of similarity with the Reference area.Conclusions: The Agroforestry activity contributes in a certain way in the maintenance of the diversity and composition of vascular plants of the Tamaulipan thorn scrub studied; and this activity does not allow to change to a large extent the composition and structure of this type of vegetation. |

Antecedentes y Objetivos: Los estudios de comunidades vegetales permiten conocer los impactos causados por las actividades agrícolas y pecuarias, especialmente en las zonas áridas. El objetivo de este trabajo fue contrastar la diversidad, composición y estructura de los estratos arbóreo y arbustivo de tres áreas (Agroforestal, Regenerada y Referencia) del matorral xerófilo.Métodos: Se establecieron tres áreas con cuatro sitios de muestreo de 1600 m2 cada una, elegidos al azar, en donde se censaron y registraron los individuos arbóreos y arbustivos. En cada área se calcularon parámetros ecológicos, así como los índices de Shannon y Margalef.Resultados clave: Considerando las tres áreas, se registró un total de 25 especies de plantas vasculares pertenecientes a 22 géneros y 15 familias. Fabaceae fue la familia mejor representada con nueve especies, siendo el género Acacia el que tuvo un mayor número (tres). Los valores de riqueza de especies, el índice de Shannon, índice de Margalef y abundancia, entre el área Referencia y Agroforestal, fueron similares, y en ambos los resultados fueron significativamente mayores que los valores del área Regenerada. El área Agroforestal presentó menor abundancia pero mayor dominancia comparada con las otras dos áreas estudiadas y fue el área que alcanzó el mayor porcentaje de similitud con el área de Referencia.Conclusiones: La actividad Agroforestal contribuye en cierta manera con el mantenimiento de la diversidad y la composición de plantas vasculares del matorral espinoso tamaulipeco estudiado; y dicha actividad no permite cambiar en gran medida la composición y estructura de este tipo de vegetación.
