What is a noxious weed?
"Noxious weed" is a designation for any plant that is harmful to local habitats and ecosystems, or to humans, livestock, and crops. They typically aren't native to the area and without the biological controls they would normally have (e.g. animals that eat them in their home range) they can spread out of control and displace other plants, decreasing biodiversity.
