Idaho Weed Awareness Campaign.

Idaho State Department of Agriculture.

The primary purpose of the Idaho State Department of Agriculture's (ISDA's) noxious weed cost share grant program is to accelerate the attack on invasive weeds by supplementing local funds and resources, not replacing them. Cost sharing is also intended to provide additional incentives for local landowners, officials, and citizens to work collaboratively to develop a more comprehensive and effective noxious weed management program.
