Noxious weeds are non-native, invasive plants which, when introduced, quickly dominate the landscape. They proliferate to the point they crowd out other plants beneficial to wildlife and domestic animals. Wildlife and grazing animals do not often eat noxious weeks because of thorns, spines, or chemical content.

Russian Knapweed (Centaurea repens)

Perennial Pepperweed (Lepidium latifolium L.)

Leafy Spurge (Euphorbia esula L.)

Saltcedar (Tamarix ramosissima Ledeb)

Canada Thistle (Cirsium arvense L.)

Scotch Thistle (Onopordum acanthium L.)
