Frequently Asked Questions

What are noxious weeds? 

Noxious weeds are plants that are not native to Idaho. They are incredibly destructive to the local ecology, livestock, crop yield, and the natural landscape. A plant is placed on the noxious weed list after the state has determined that it can cause considerable damage to wildlife, agriculture, health, and recreation.

Weeds can be introduced to the local environment through seed dispersal. Seeds can travel on clothes, equipment, animals, etc. Others are introduced as garden ornamentals or as aquatic plants for aquariums.

What is the Idaho Noxious weed law? Does Blaine County have a Noxious Weed Ordinance?
