A vegetation management system includes a computing system including a processor having an associated memory that is configured for implementing a vegetative modeler including an image analyzer and at least one 3-dimensional (3D) vegetation growth model. The vegetative modeler is for analyzing images of vegetation that is growing around electrical power lines of an electric utility including identifying locations of the vegetation relative to locations of the electrical power lines and to identify specific types of the vegetation. The 3D vegetation growth model utilizes at least the locations of the vegetation relative to the locations of the electrical power lines and the specific types of the vegetation to generate a predicted timing of encroachment of the electrical power lines by the vegetation to identify future encroachment areas. A scheduler is for scheduling vegetative maintenance of the vegetation for the future encroachment areas.
