I've heard a lot about pesky weeds in Idaho over the years. However, I was surprised to read the statistics in a recent Post Register article picked up by the Spokesman-Review.
Many of Idaho's wildlife management plans have sections dedicated to weeds as a habitat threat. I know that I'll be looking for additional information so that I'm personally not inadvertently spreading noxious weeds. I'll start with Idaho Department of Agriculture's Noxious Weed Program.
