Noxious Weeds Profiles
Important: Most "weed problems" are really "people problems" from poor land management and a lack of ecological insight. It is easy to reach for a tool like fire, mowing, or herbicides to attack an out-of-control weed, but often those tools do little to get to the root cause of the weed infestation, and sometimes make the problems worse.
For example, careless use of herbicides kills out many desireable native species and simplifies ecosystems, allowing weeds to re-invade later on. The arrowleaf balsamroot in this picture is one native plant that was sprayed with herbicides.
