The ecosystem processes that take place within forest ecosystems have a very close relationship with the structure that they canshow, therefore being able to characterize it allows creating better strategies to maintain and improve them. The present study waselaborated to determine the relationships and competition of Picea, Abies, Pseudotsuga and Cupressus, based on the growth,development, and different types of species mixture in a temperate forest of Durango. A dot pattern analysis was used to evaluateaggregation, species mixture, dominance, and dimensional differentiation. The dasometric data were obtained from 10 permanentplots (2500 m²), considering: diameter> 7.5 cm, height, azimuth, and distance. IVI and different diversity indices were estimated; inaddition, a total of 1576 structural groups were analyzed. The average density for the evaluated areas was 629 N ha-¹, highlightingPinus with 660 N ha-¹, the genera with the highest IVI were Pinus and Picea. Regarding true diversity, the plot obtained the highestvalue. Through the Clark & Evans aggregation index, 90% of the areas showed a clustering trend in the genres included. Throughthe neighborhood indices, the areas showed a moderate mix, with a random and structurally co-dominant distribution.
