Noxious Weeds: The Cancer on Our Land

Noxious weeds pose a serious threat to all Idahoans and to the land we call home. Control and managing Idaho’s 67 noxious weed species requires an understanding of the problem, and that begins with detection and identification of noxious weeds.

Notice To Control Noxious Weeds

It shall be the duty and responsibility of all landowners to control noxious weeds on their land and property, in accordance with Title 22, Chapter 24 (22-2407).


 

For help with identification, control methods, spray equipment to loan and information about our CWMA cost-share program, contact Valley County Weed Control at 55 Gold Dust Road.

Noxious weeds cost millions of dollars to Idaho by:

Fouling recreation sites from use Chocking streams & waterways
Poisoning & injuring livestock & humans Crowding out beneficial native plants
Degrading wildlife habitat Creating wild fires in our forests & Idaho’s range land

The spread of noxious weeds in Idaho may signal the decline of entire ecological watersheds. They severely impact the beauty and create widespread economic losses. Noxious weeds are huge problems for our urban as well as rural areas, and for private, state, and federal lands. Valley County noxious weed species spare no segment of society – rancher, hunter, hiker’s and fisherman alike – and when unmanaged they spread rapidly and unceasingly and silently.

Noxious weeds presently in Valley County include:

Scotch Thistle Spotted Knapweed Tansy Ragwort
Whitetop Purple Loosestrife Yellow Toadflax
Poison Hemlock Houndstongue Leafy Spurge
Oxeye Daisy Hoary Alyssum Rush Skeletonweed
Eurasian Watermilfoil Orange Hawkweed Canada Thistle
Dalmatian Toadflax Diffuse Knapweed Field Bindweed
