| description | Structural characterization of the vegetation facilitates forest management decision-making and prescription of silvicultural practices appropriate to the landowner´s purposes. In the ejido Nopalillo, municipality of Epazoyucan, located southeast of Hidalgo, Mexico, forest harvest is practiced in three associations dominated by Pinus montezumae Lamb., Pinus pseudostrobus Lindl., and Pinus patula Schl. et Cham., respectively. In addition, the ejido has an area dominated by Pinus-Quercus used as a conservation area. To characterize these four conditions, information from 79 sampling plots was analyzed, in which the arboreal, shrub and herbaceous strata were evaluated. Structural analysis of the vegetation was based on the Importance Value Index, Margalef, Simpson and Sorensen diversity indexes, as well as the vertical and horizontal structure in each association. The Pinus-Quercus area presented the largest basal area (28 m2/ha), normalized diameter (DBH) and average height (20.5 cm and 10.7 m), respectively, the highest proportion of large trees (DBH>60 cm) and species composition different from the other associations. The greatest total diversity was found in the areas under timber harvesting, and the highest tree diversity in the conservation area. The results can be used as a reference to identify the effect of silvicultural practices, they are also the basis for the development of strategies for forest management, conservation, and use. |

La caracterización estructural de la vegetación facilita la toma de decisiones de manejo forestal y la prescripción de prácticas silvícolas adecuadas a los propósitos del propietario. En el ejido Nopalillo, municipio de Epazoyucan, al sureste de Hidalgo, México, se realiza aprovechamiento forestal maderable en tres asociaciones arbóreas, cada una dominada por Pinus montezumae Lamb., Pinus pseudostrobus Lindl. y Pinus patula Schltdl. et Cham., respectivamente; además, el ejido cuenta con una superficie dominada por Pinus-Quercus que ha sido destinada a la conservación. Con el objetivo de valorar composición, diversidad y estructura de estas asociaciones, se analizó información de los estratos arbóreo, arbustivo y herbáceo de 79 sitios de muestreo. Se calcularon índices de valor de importancia, de diversidad de Margalef, de Simpson y de Sorensen y se describen las estructuras vertical y horizontal de la vegetación. La asociación Pinus-Quercus presentó la mayor área basal (28 m2/ha), diámetro normal y altura promedio (20.5 cm y 10.7 m, respectivamente), la mayor proporción de árboles de dimensiones grandes (diámetro normal > 60 cm) y una composición de especies diferente a las otras asociaciones. La mayor riqueza de especies se registró en las áreas bajo aprovechamiento maderable, pero la diversidad arbórea fue superior en el bosque de Pinus-Quercus. Estos resultados se proponen como referentes para la identificación de los efectos de las prácticas silvícolas sobre la vegetación y para el desarrollo de estrategias de manejo, conservación y uso del bosque.
