| description | Background and Aims: Abies religiosa forest or sacred fir forest is distributed in isolated patches and its largest continuous areas are located in the Transmexican Volcanic Belt. There are several studies that provide essential information on ecological and floristic aspects of the sacred fir forest in Mexico. However, basic ecological questions still need to be answered, which can be very useful to propose and establish management and conservation strategies for this type of vegetation. For this reason, the objectives of this investigation were: (1) to estimate the variation in the population structure of Abies religiosa and, (2) determine the tree and shrub structure and composition of the sacred fir forest, under different conditions of management and elevation.
Methods: The study area included five localities with sacred fir forest in Hidalgo State, with different management and altitude conditions. In total, 25 sampling plots were placed (0.01 ha each), to obtain standard data at the population level (height, density, diameter) and community level (density, basal area and frequency of species).
Key results: Three populations of A. religiosa were classified as dynamic due to the predominance of small individuals. The remaining two were normal with a predominance of intermediate-sized specimens. At the community level, 15 species of trees and 15 of shrubs were recorded. The structure of the forest differed in some localities, mainly among the farthest geographically, confirming the role of forest management, and local environmental conditions.
Conclusions: Abies religiosa dominated the canopy in all localities. The structural characteristics at both population, and community levels differed between sampling locations, probably due to the forest management and the different local environmental conditions. |

Antecedentes y Objetivos: El bosque de Abies religiosa o bosque de oyamel se distribuye en parches aislados y sus áreas continuas más extensas se localizan en la Faja Volcánica Transmexicana. Diversos estudios aportan información sobre aspectos ecológicos y florísticos del bosque de oyamel en México. Sin embargo, aún es necesario responder cuestiones ecológicas básicas, que pueden ser útiles para proponer y establecer estrategias de manejo y conservación de este tipo de vegetación. Por esta razón, los objetivos de la presente investigación fueron: (1) estimar la variación en la estructura poblacional de Abies religiosa y (2) determinar la estructura y composición arbórea y arbustiva del bosque de oyamel bajo diferentes condiciones de manejo. Métodos: El área de estudio incluyó cinco localidades con bosque de oyamel del estado de Hidalgo, México, con diferentes condiciones de manejo y altitud. En total se colocaron 25 parcelas de muestreo (0.01 ha cada una) para obtener datos estándar a nivel poblacional (altura, densidad, diámetro) y comunitario (densidad, área basal y frecuencia de las especies). Resultados clave: Dentro de las cinco localidades, tres poblaciones de A. religiosa se clasificaron como dinámicas, por presentar predominio de individuos pequeños; las dos restantes fueron normales, con alto porcentaje de plantas de tamaño intermedio. A nivel de comunidad, se registraron 15 especies de árboles y 15 de arbustos. La estructura del bosque difirió entre localidades, en especial las más lejanas geográficamente, corroborando el papel del manejo del bosque y de las condiciones ambientales locales. Conclusiones: Abies religiosa dominó el dosel en todas las localidades. Las características estructurales a nivel de población y comunidad difirieron entre sitios de muestreo probablemente a causa del manejo forestal y de las diferentes condiciones ambientales locales.
