Estructura del arbolado y caracterización dasométrica de la segunda sección del Bosque de Chapultepec.

Chapultepec Forest is the largest and most visited urban green area (UGA) of Mexico City and for these reasons, the protection and conservation of this place is a relevant issue to maintain the generation of the environmental services and benefits that it provides. Despite the importance of this area, there is a lack of information about the horizontal structure and indicators of the tree stands located in this place, as well as for the rest of the UGA of the city and the country, although some floristic or sanitary conditions studies had been done in some of them. The aim of this paper was to determine the dendrological and dasometric characteristics of the stands at the 2nd section of Chapultepec Forest, according with the information obtained from a total tree inventory, complemented with 111 sampling sites of 500 m². The estimated mean of trees per site was 295/ha, the mean crown cover value was 27,19 m² and the canopy cover in the area exceeds 80% of the total surface. The mean basal area was 0,10 m² and the stems occupied 0,32% of the total surface. This data will provide basic indicators for the 2nd section tree stands and a reference for future research projects and characterization of UGA in the city. In addition, the information is basic to sustain the management that requires the urban forest of Mexico City. [ABSTRACT FROM AUTHOR]
