Weeds and Invasive Plants
A weed is any plant growing where it is not wanted. As a forest landowner, you will ultimately decide what is or is not a weed on your property. However, invasive and noxious weeds are those that can significantly impact the vegetation structure and ecosystem function of your forest. Invasive weeds can displace desired native plants, lead to loss of wildlife habitat, and increase your wildfire risk.
Below are resources to assist you with weed identification, weed prevention, and management.
