Spatial distribution patterns of trees in a Pseudotsuga menziesii forest in Chihuahua, Mexico
The objective of this study was to characterize the tree spatial structure patterns of the mature forest in the Chihuahua, Mexico state, where conifers of conservation importance coexist as Pseudotsuga, Picea, and Abies. The data were collected from eight sampling sites of 1000 m2. 203 structural g...

| description | The objective of this study was to characterize the tree spatial structure patterns of the mature forest in the Chihuahua, Mexico state, where conifers of conservation importance coexist as Pseudotsuga, Picea, and Abies. The data were collected from eight sampling sites of 1000 m2. 203 structural groups were analyzed in a general way, Pseudotsuga generated 84, Quercus 22, and Pinus 42, these reflected a random distribution according to index (Wi), while the degree of mixing (Mi) stated that the reference species has more than two neighbors of different species, no dominant diameters and heights were generally recorded as (UDi) and (UHi) showed similar values in each of the degrees of dominance, the dimensional differentiation (TDi), (THi) was moderate, similar to studies in disturbed and under-managed forests. Knowledge of the dynamics of mature forests is vital for a more accurate description of the relationships between species in a more authentic way, and it can be the basis for conservation or future restorations in disturbed areas. |

El objetivo de este estudio fue caracterizar los patrones de distribución espacial de un bosque maduro en el estado de Chihuahua, México, donde coexisten coníferas de importancia para la conservación como Pseudotsuga, Picea y Abies. Se utilizó un análisis de patrón de puntos para evaluar mezcla de especies, diferenciación y dominancia dimensional. Los datos se obtuvieron de ocho sitios de muestreo de 1000 m2. Se analizaron de manera general 203 grupos estructurales, Pseudotsuga generó 84, Quercus 22 y Pinus 42, reflejando una distribución aleatoria de acuerdo con el índice de uniformidad de ángulos (Wi), mientras que el grado de mezcla (Mi) manifestó que la especie referencia cuenta con más de dos vecinos de diferente especie. No se registraron diámetros y alturas dominantes de manera general ya que (UDi) y (UHi) mostraron valores similares en cada uno de los grados de dominancia, la diferenciación dimensional (TDi), (THi) fue moderada, similar a estudios en bosques perturbados y bajo manejo. El conocimiento de la dinámica de bosques maduros es vital para una descripción precisa de las relaciones entre especies de manera más auténtica y puede ser base para la conservación o futuras restauraciones en áreas perturbadas.
