Promoting Research, Education, and Awareness of Weeds in Managed and Natural Ecosystems

Weeds and invasive plants impact the world around us and our daily lives. They can reduce crop yields, choke waterways, trigger allergies, disrupt the natural habitats of plants and animals, create fire and safety hazards, and reduce aesthetic and property values. These are just a few of the environmental impacts caused by weeds.
