Noxious Weed Control

When weeds encroach on otherwise healthy habitats, it often creates a firestorm of events that deteriorate native habitats and pose a risk to the wildlife, livestock, ranchers, and recreationists that utilize those lands.  Noxious weeds compete with natives for resources; are often hardier and more prolific; and can sometimes wipe out all vegetative diversity in an area, creating a single monoculture.  Once established, controlling the spread of weeds may be very difficult, if not impossible.  Prevention and early detection are critical to proper weed management.  Middle Park Conservation District works to educate landowners on noxious weed identification and control and curb the encroachment of noxious weeds throughout Grand and Summit Counties.
