The School of Forestry Engineering developed a database of 69 principal properties: the data was collected using a data matrix to the information with an analysis, obtaining a total of 229 properties for the present study. The GIS data through the use of ArcGis 10.1 developed maps which demonstrated the main characteristics of the indicators. In order to determine sustainability, the data matrix was applied adapting it to the needs that were required which determined the sustainability as 61,97%, this was interpreted as “AVERAGE” sustainability.
