| description | Background and Aims: Forest management causes changes in the composition, structure and functioning of the forest. The objective of this study was to compare the structure of tree species over a period of 10 years in a forest in Durango, Mexico.
Methods: The data come from trees with DBH greater than or equal to 7.5 cm (at a height >1.3 m) located in permanent sites that were evaluated over a five-year interval (2007, 2012, 2017). Three height strata were defined for each year of measurement under the Pretzsch index methodology taking into account the highest height of each measurement. In each stratum, the structure was assessed through the importance value index (IVI), alpha diversity (α) with species richness (S) and the Shannon-Wiener index (H’). All dasometric variables per stratum of each measurement were compared with ANOVA of a factor to determine the existence of statistically significant differences between the evaluations.
Key results: Although there was an increase in basal area, volume and coverage from 2007 to 2017, this was not statistically significant. Strata II and III showed the greatest increase in basal area and volume. The coverage was greater than 100%, with the highest contribution being stratum III. The composition of species was similar in the three measurements, with stratum III being the most diverse. Pinus durangensis was the species of greatest ecological importance in strata I and II, while Quercus sideroxyla presented greater relevance in stratum III.
Conclusions: The comparison made over a period of 10 years (2007-2017) allowed us to determine that the tree vegetation of the evaluated community remains unchanged with respect to the diversity of species, while the basal area and volume tend to increase. |

Antecedentes y Objetivos: El manejo forestal ocasiona cambios en la composición, estructura y funcionamiento del bosque. El objetivo de este estudio fue comparar la estructura de especies arbóreas en un periodo de 10 años en un bosque de Durango, México. Métodos: Los datos provienen de árboles con DAP mayor o igual a 7.5 cm (a una altura >1.3 m), ubicados en sitios permanentes que fueron evaluados en intervalos de cinco años (2007, 2012 y 2017). Se definieron tres estratos de altura para cada año de medición, bajo la metodología del índice de perfil vertical (A) de Pretzsch tomando en cuenta la altura mayor de cada medición. En cada estrato se evaluó la estructura a través del índice de valor de importancia (IVI), la diversidad alfa (α) con la riqueza de especies (S) y el índice de Shannon-Wiener (H’). Todas las variables dasométricas por estrato de cada medición se compararon con un ANOVA de un factor para determinar la existencia de diferencias estadísticamente significativas entre evaluaciones. Resultados clave: Aunque hubo un aumento en el área basal, el volumen y la cobertura de 2007 a 2017, este no fue estadísticamente significativo. Los estratos II y III presentaron el mayor aumento en el área basal y el volumen. La cobertura fue superior a 100%, presentando mejor contribución el estrato III. La composición de especies fue similar en las tres mediciones, siendo el estrato III el más diverso. Pinus durangensis fue la especie de mayor importancia ecológica en los estratos I y II, mientras que Quercus sideroxyla presentó relevancia alta en el III. Conclusiones: La comparación realizada en un periodo de 10 años (2007-2017) permitió determinar que la vegetación arbórea de la comunidad evaluada se mantiene sin cambios respecto a la diversidad de especies, mientras que el área basal y el volumen tienden a aumentar.
