Theft of trees can also threaten the sustainability of forest management and function. Geographic Information Systems (GIS) can help forest management. With the ability to build GIS spatial model. The purpose of this study itself are: making maps theft of trees, identifying factors that influence the theft of trees, and create a map of their vulnerability to theft trees. Map of tree theft is divided into five classes, namely tree thefts: low, pretty, medium, high, and very high.

Spatial model obtained the degree of vulnerability maps obtained tree theft is divided into five, namely: low-prone, quite vulnerable, being vulnerable, high-prone, and very vulnerable.
