Noxious weeds impact everyone in one form or another. They compete for light, water, and nutrients, and some release compounds that are harmful to other plants. Our land and resources are suffering losses that affect our ability to produce higher crop yields and promote desirable grazing and public use. Weeds cause fire hazards, site obstructions, and poisonings. They encourage increased insect populations, undesirable soil conditions, and diseases in desirable plant communities. The bottom line - weeds are taking up valuable space. Whether you are a producer, consumer, or recreationalist, you are paying the ultimate price. Noxious weeds are everyone's problem!

Since the early 1970’s, Twin Falls County has maintained an active roll against weeds. The county encompasses approximately 1.2 million acres. The responsibility of the county regarding Noxious Weeds is outlined in Idaho Code, Title 22, Chapter 24. The County Commissioners are responsible to see that lands within the County are assessed for the presence of noxious weeds and prompt control practices from landowners and managers. A Weed Superintendent is employed to carry out these responsibilities.

Eighteen of the State's 36 noxious weeds are established in various degrees within the county. While some are widespread and have been around for many years, others have been recently introduced. Since 1994, Twin Falls County has seen new noxious invaders such as Yellow starthistle, Dyer's wo ad, Rush skeletonweed, and Toothed spurge. Without county involvement and help from a motivated public, these new invaders would have gained a foothold. Accomplishment depends on public awareness, support, and action. This department strives to provide information and promote support and action from all landowners and managers in an effort to protect our land and resources from noxious weeds.
