Noxious Weeds and other invasive species threaten all of our natural resources. They can destroy native plant and animal habitat, damage recreational areas, clog waterways, lower land values, decrease agricultural crop yields, and some can even poison humans and livestock.
Noxious Weeds are also a leading cause of species endangerment under the Endangered Species Act. The Iowa Department of Agriculture and Land Stewardship, along with Hardin County, has declared 31 species of plants as Noxious.
