In 2017, the diversity of woody species in the community of Xaltepuxtla, Puebla was evaluated in a remnant of altered mountain mesophilic forest, ornamental system and silvopastoral system in order to know the tree diversity and propose species of high ecological value for their restoration. Ecological indices and a systematic sampling design were used with predetermined distances in grid form. 22 sites were sampled using quadrants with central point for tree vegetation with 100 m2 sites and embedded boxes for shrub and herbaceous vegetation. Wealth, abundance and diversity of woody species were obtained with estimators of Jacknife 1, relative abundance index (IAR) and Shannon-Wiener index. 19 species were registered in 15 families and 18 genera. The species with the greatest relative abundance per site were: Chamaecyparis lawsoniana (IAR= 0.96), Rhododendron simssi (IAR= 0.46) and Chamaecyparis. thyoides (IAR= 0.25). The sites with the greatest diversity were: 22 with an index of 2.54 and 20 and 21 with indexes of 2.53 respectively. The greatest diversity by condition was in the RBMM with an index of 2.92. With the Kruskal Wallis test, no significant differences were obtained between the ecological estimators, so all three conditions are subject to the same level of alteration. It was possible to know the wealth, abundance and diversity of the woody species in the study area.
