To create treatment areas for invasive plant species within the San Juan National Forest in the state of Colorado. Part of this process will be to define areas in which chemical and non-chemical treatments may be used within the forest. Here I used python code, to create treatment areas for invasive plant species by creating polygons around the forest roads. These polygons will define the non-chemical treatment areas. **Note: Credits to ESRI, this analysis was did with help of Spatial analysis Course by ESRI.
