Resumen: "Extent and distribution of urban green spaces (UGS) in Mazatlan (Mexico) are analyzed using remote sensing and GIS techniques. Vegetated areas (2,270 ha), a third of the urban area in 2015, were reclassified into green spaces (GS), urban tree (UT) and open spaces (OS), based in the normalized difference vegetation index, relating them with demographic and socioeconomic data. UGS allocation per capita amount 55 m2, mainly represented by the UT class, with the largest patches associated with low developed and very high marginalized areas, and also with very low marginalized sectors, while the lowest allocation correspond to
medium and low marginalization, highly populated sector, without significant correlations. Despite the USG allocation, it is required a better urban planning to maintain public UGS and to protect the local flora, threatened by the introduction of exotic, ornamental species (64% of UT), to guarantee the provision of ecosystem services to the population."
