The spread of noxious weeds can be controlled if a concerted effort is make among public land users, including recreationists, miners, ranchers and state and government agencies.
The most effective method of control is to prevent noxious weeds from growing and expanding their range of invasion. By recognizing invasive weeds, reporting infestations to appropriate agencies, and following up with treatment, we can prevent the spread of noxious weeds on Nevada's rangelands.
Gaining control of noxious weed infestations can be difficult. In most of the knapweeds and thistles, cutting the root off before seed formation will destroy the weed and prevent seeding. However, cutting off other noxious weeds, such as leafy spurge and perennial pepperweed, will not control them and they will spread rapidly through root sprouting.
Noxious weeds affect people and the land in many different ways.
- Thorny, spiny plants make recreation areas inaccessible.
- The presence of noxious weeds decreases land and real estate values.
- The increasing need for control of weeds in crops raises food prices.
- Noxious weeds increase fire intensity and frequency in range and forest lands.
- Noxious weeds out compete native plants which decreases biodiversity and habitat.
