MARTINEZ JUAREZ, Graciela et al. Description of the linear trees of Puebla City by degree of marginalization and street. Rev. mex. de cienc. forestales [online]. 2022, vol.13, n.70, pp.85-111.  Epub 09-Maio-2022. ISSN 2007-1132.  https://doi.org/10.29298/rmcf.v13i70.830.

Urban trees are a fundamental part of the natural landscape within cities, as they reduce the negative effects caused by economic activities and contribute to improve the quality of life for the inhabitants of all social classes. The aim of this study was to make a diagnosis of the urban trees in streets of Puebla City in areas with different degrees of marginalization and type of existing roads. A stratified random sampling was carried out in public roads from May to October 2019. The species, total height, height to the first branch and height to canopy, basal diameter, diameter to the breast height, canopy cover diameter, also health condition, status of development and conflicts with infrastructure were determined. A total of 2 188 trees were recorded, 2 068 of which were found alive, which belong to 31 families, 56 genera and 75 species; 73.33 % are introduced species and only 26.67 % are native. The results from this study highlight the influence that socio-economic aspects have on the composition and structure of urban trees, mainly in street trees, being important to recognize that in the development of management plans and management of public urban trees it is necessary to integrate the different social and urban aspects that each urban center has.
