How are noxious weeds different from regular weeds?
Federal and/or State law designates plants as “noxious” if they are overly aggressive, difficult to manage, parasitic, poisonous, carriers or hosts of serious insects or diseases. Noxious plants may also be non-native, new to, or not common to the United States. In most cases, noxious weeds have a direct impact on croplands. The BLM is also concerned with other invasive weeds that cause harm, but may not necessarily be designated as Federal or State noxious listed weeds.
