Went to look up noxious weeds on the USDA+Forest Service website that used to have this information and when I click a plant name, I get "You are not authorized to access this page."
So that's how that's going. Thanks DOGchE.

Idaho Panhandle National Forests - Noxious Weeds
What's a noxious weed?Noxious weeds are aggressive plants which are not native to our area. They crowd out beneficial plants and create a "monoculture" of just themselves. They are often harmful to humans, livestock, wildlife, the environment or the economic well-being of the area.
