What is a noxious weed?
Noxious is a legal designation. The State of Idaho designates exotic invasive plant species as noxious if they pose a serious threat to agriculture and/or the environment. Landowners are required to control noxious weeds on their property. Idaho has both terrestrial and aquatic noxious species.
Are all weeds noxious?
No. Some exotic species are not invasive. Some exotic invasive species have not been listed- usually these do not compete well in undisturbed areas or there is a lag is legislation.
How did weeds get here?
Noxious weeds and other exotic invasive plants were introduced by humans either as crop seed contaminants, ornamentals that then escaped, or from dumping aquariums plants into streams. Most problematic species are introduced from climatically similar regions in Eurasia.
How can plants be "bad"?
Exotic invasive weeds evolved in their home range with viruses, fungi, mites, insects, and other plants that kept their population in balance. Most of these species have evolved to exploit disturbance. In their introduced range, they do not have their predators and pathogens to keep them balanced. This allows them to displace natives in disturbed sites like roadsides, overgrazed pastures, and burned areas.
