RESUMEN/ A partir de un catastro de árboles realizado durante los meses de junio a septiembre del año 2014, este estudio analiza la vulnerabilidad ambiental del arbolado urbano público (VAAUP) para la comuna de Providencia, Chile. Las variables a considerar en el análisis fueron Fase de Crecimiento, Estado Fitosanitario y Estado de Afectación Biótica, los que combinados en una matriz de valoración, muestran diferencias espaciales significativas de vulnerabilidad. Considerando la totalidad del área de estudio, las especies más representativas fueron Acer negundo L., Robina pseudoacacia L., y Platanus orientalis L. (el 50% del total de la población arbórea). Las dos primeras especies son altamente vulnerables, lo que queda evidenciado en el mapa de VAAUP diseñado en un software de código abierto de Sistema de Información Goegráfica. Los resultados presentados buscan mejorar la gestión ambiental urbana de la comuna. ABSTRACT/ Based on a tree register made during June to September 2014, this study discusses the environmental vulnerability of public urban trees (EVPUT) in the district of Providencia, Santiago, Chile. The variables considered in the analysis are Growth Phase, Plant Health Status, and Biotic Stress Status, which combined in an assessment matrix show considerable spatial differences regarding vulnerability. Considering the entire study area, the most representative species were Acer negundo L., Robina pseudoacacia L., and Platanus orientalis L. (50% of total tree population). The first two species are highly vulnerable, which is shown in the EVPUT map designed with a Geographic Information System's open code software. The results aim at improving the commune's urban environmental management.
