摘要

A study was conducted on the forest structure of Pinus hartwegii Lindl., located at the Cofre de Perote National Park. The density, diameter, height and wooded coverage were evaluated along an altitudinal gradient from 3500 to 4000 meters in 20 plots of 100 m2. The structure of the population was found to be in the form of an “inverted J”. No statistically significant differences were found for any of the above-mentioned variables evaluated in the altitudinal range. A high density of suppressed individuals was found to occur at 50% of the sites sampled. Given the suppression characteristics of the trees, shelterwood is suggested for a better development of the woodland mass, as well as the introduction of mycorrhizal plants.
