This guide is intended to assist with identification of invasive plants and provide information on controlling these problem plants. Included are both non-chemical means of control as well as information on proper use of herbicides where chemical controls are needed. The choice of control measure depends on the size and nature of the infestation. If dealt with early enough, invasive plant problems can often be eliminated by non-chemical methods. However, a herbicide-based approach may be required to control an infestation that has become well established or widespread.
