Estructura y regeneración natural de Peltogyne mexicana en el Parque Nacional el Veladero, Acapulco, Guerrero

Peltogyne mexicana is an endemic arboreal species of Guerrero, which is threatened by deforestation and illegal logging. That said, the purpose is to know the structure of the forest population and the ecological processes that occur in the population. A guided sampling was carried out within two ecological conditions in the Eastern Polygon of El Veladero National Park (A and B), whose differences are: height, exposure, slope, rockiness and coverage, in each ecological condition four sampling units were placed, the linear sampling technique was used for analysis of natural regeneration, each quadrant has a total area of 400 m2 for fustals (individuals with DAP> = 10cm), subdivided into two quadrants, the quadrant of 10 x 10 m for saplings (plants with DAP> 2cm and 1.5m) and the 5 x 5m quadrant for seedlings (seedlings with a height less than 1.5m); To analyze the structure, individuals older than 1.5 m were selected. No significant differences were observed between conditions for the height and diameter variables, however, it was observed that the highest values are for condition A. The dominant diameter class is from 0 to 25 cm for both ecological conditions. Nearly 70% of the population corresponds to juvenile classes (saplings and seedlings), thus the majority of individuals remain in lower strata later becoming ecologically dead individuals. With this, the permanence of P. mexicana is at risk, since the strong relationship with the environmental conditions where it develops, the high death rate in juvenile categories and anthropogenic pressures threaten their permanence. Peltogyne mexicana é uma espécie arbórea endêmica de Guerrero, que é ameaçada pelo desmatamento e pela talha ilegal. Com base no acima, para conhecer a estrutura da população florestal, conheça os processos ecológicos que ocorrem na população. Uma amostragem guiada foi realizada dentro de duas condições ecológicas no Polígono Oriental do Parque Nacional El Veladero (A e B), cujas diferenças são: altura, exposição, inclinação, rocha e cobertura, em cada condição ecológica foram colocadas quatro unidades de amostragem, A técnica de amostragem linear foi utilizada para análise de regeneração natural, cada quadrante tem uma área total de 400 m2 para fustales (indivíduos com DAP> = 10cm), subdividido em dois quadrantes, o quadrante de 10 x 10 m para latizas (plantas) com DAP> 2cm e 1.5m) e o quadrante de 5 x 5m para mudas (mudas com uma altura inferior
