Composition and structural aspects of oak forests of the Sierra de Zapalinamé, Coahuila, México
To determine the structure and floristic composition of the oak forest of the Sierra de Zapalinamé, we established sixty six plots of 500 m2. Density and basal area were measured for adult trees and density and cover in shrubs. Saplings were considered in concentric areas of 50 m2 and seedlings in f...

| description | To determine the structure and floristic composition of the oak forest of the Sierra de Zapalinamé, we established sixty six plots of 500 m2. Density and basal area were measured for adult trees and density and cover in shrubs. Saplings were considered in concentric areas of 50 m2 and seedlings in five areas of 1 m2. All the plants were collected and identified. Vegetation attributes were used to obtain the importance value for trees and shrubs. The vascular flora takes in 259 species and infraspecific taxa with 178 genera in 67 plant families. The forest associations were defined by Quercus greggii - Q. mexicana and Quercus saltillensis - Q. laeta; the most important oaks in the forest structure were Quercus greggii (1480 ind ha-1), Q. saltillensis (876), Q. laeta (741) and Q. mexicana (284). The mature tree density (4448 ind ha-1) differs opposed to the seedlings (269 ind ha-1) and saplings (175 ind ha-1). The oaks with the highest basal area were Quercus greggii with 9.0 m2ha-1 and Q. saltillensis 6.62 m2ha-1. Thirty seven pairs of species were analyzed and 62% have significant association. The shrubs with the highest value of covering were: Garrya glaberrima, Ageratina ligustrina and A. saltillensis. The herbs were 72.9% of the flora and the most common elements were: Artemisia ludoviciana, Pleopeltis guttata, Cheilanthes tomentosa and Achillea millefolium. The species number diminishes when the altitude increases. |

Con la finalidad de conocer la estructura y composición florística de los bosques de encino de la Sierra de Zapalinamé, se evaluó la densidad y área basal del arbolado adulto, la cobertura de los arbustos y se registró la identidad de los componentes herbáceos en 66 parcelas de 500 m2. Los árboles juveniles se midieron en sitios de 50 m2 y la regeneración en cinco sitios de 1 m2. Los atributos de la vegetación fueron utilizados para obtener el valor de importancia ecológica para las especies leñosas. La flora vascular es de 259 especies y taxa infraespecíficos en 178 géneros y 67 familias. Las asociaciones vegetales definidas mediante el análisis de conglomerados son el bosque de Quercus greggii - Q. mexicana y de Quercus saltillensis - Q. laeta. Los encinos estructuralmente importantes son Quercus greggii (1480 ind ha-1), Q. saltillensis (876), Q. laeta (741) y Q. mexicana (284). La densidad total del arbolado adulto fue de 4448 ind ha-1 y fue mayor que la de renuevos (269 ind ha-1) e individuos juveniles (175 ind ha-1). Los encinos con mayor área basal fueron Quercus greggii (9.0 m2 ha-1) y Q. saltillensis (6.62 m2 ha-1). De las 37 parejas interespecíficas de encinos analizadas, 62% se asociaron significativamente. Los arbustos con mayor cobertura fueron: Garrya glaberrima, Ageratina ligustrina y A. saltillensis. El estrato herbáceo representó 72.9% de la flora y sus elementos más comunes fueron Artemisia ludoviciana, Pleopeltis guttata, Cheilanthes tomentosa y Achillea millefolium. El número de especies decreció con el aumento de la altitud.
