Cheat grass, knapweed, St;Johns wort, hound's tongue, cockle burrs, the list goes on. Livestock spreads a lot of it and fire helps control some so it's a tough call in a lot of situations. In a lot of areas in North Idaho, knapweed is so prevalent it looks like they want to grow it. The one thing certain is that everyone can't be happy with administration of BLM lands. GD
