Is there a deadline for this project?


In this project, students will receive an introductory lesson about noxious weeds, participate in an identification and weed-pull activity during ROES camp, and complete a follow-up in the spring with a weed-pull along the bike path near school. By participating in this project in both the fall and spring students will be able to observe and identify noxious weeds in various stages of their life cycle. It is important to recognize noxious weeds at various stages of their life cycles as the effectiveness of the various control options fluctuates throughout the life cycle.

The ERC?s Pesticide Action program is working to reduce the use of pesticides, herbicides and chemical fertilizers in the Wood River Valley. One of our projects is to oversee the maintenance of and education around the Wood River Community Knapweed Bio-Control Insectary: a nursery for insects that eat Spotted-Knapweed (a very common and problematic noxious weed)

In an effort to control weeds, landowners often rely on chemicals that are destructive to native plant communities and harmful to environmental and human health. Chemicals are used every day to maintain school grounds, playing fields and public paths, unnecessarily exposing our community to carcinogens, asthmagens, and developmental toxins. In Blaine County, a minimum of 11 pesticides are routinely sprayed, many of which are known neurotoxins and endocrine disruptors that cause reproductive damage and are linked to various cancers. One non-chemical weed strategy the ERC is promoting is the use of is bio-control. The ERC, in collaboration with the Forest Service and Blaine County Noxious Weed Department, maintains the Wood River Community Knapweed Bio-Control Insectary at the Sawtooth National Recreation Area Headquarters where root-boring weevils (insects) are being grown to provide a chemical-alternative weed control to the Valley. Currently it costs /weevil; however, with this local insectary, each weevil will be given out free of charge and will be more effective as it will be habituated to our local ecosystem.
