Invasive Species

Non-native species, or invasive species, are more than just a nuisance, they are the of cause major environmental and economic damage in the United States. Nationwide, there are approximately 50,000 foreign species. These non-native species have resulted in billions of dollars worth of expenditures in damages to crops, costs in treatment, habitat restoration, and other associated expenses. Moreover, 42% of threatened and endangered species are at risk at least partially as a result of invasive species; approximately 18% are at risk primarily as a result. Community awareness about the threat posed by invasive species is key to preventative invasive species control.


Invasive Species Identification and Control Priorities

The Teton County Weed and Pest District (TCWP) maintains an up-to-date list of weed and pest control priorities, including noxious weeds. This list provides information for outlining the noxious weed priorities for all of the Teton Conservation District. The weeds contained in this list are divided into four priority areas:

  1. Rare Infestation: This priority category includes exotic plants that are considered highly invasive and pose the largest threat to native plant communities and the larger ecosystem. To combat the threat posed by these plants, early detection followed by a rapid response is key. The goal is total eradication of these plants within the Teton Conservation District.
  2. Localized Infestation: Species listed in this category are considered to be highly invasive and pose a high threat to native plant communities, productivity,  and the larger ecosystem. The goal with this category is to contain and reduce current infestations while preventing new infestations. 
  3. Regional Infestation: This category deals with species that are already established in large numbers but within localized areas. These species are also highly invasive, and further spreading poses a threat to native plant communities and the larger ecosystem. The focus with this category is to contain the existing infestations through the use of Best Management Practices, respond rapidly to reports of new infestations, and to stop the further  spread of these species further.
  4. Widespread Infestation: Species falling within this last category are already established in large numbers throughout the Teton Conservation District. They are highly invasive, and the goal is to prevent further spreading of these species within the county. Containment of current infestations coupled with rapid response to reports of new infestation are key to diminishing the threat posed by these species.

These photos are from a completed Invasive Species Program site located on Stateline Road in Alta, Wyoming. The site was initially sprayed 2005, with the dead growth left behind. In 2006, the site was re-sprayed, the dead growth removed, and the site seeded. Treated weeds include Common Mullein.




Learn about simple steps you can take to prevent the spread of invasive species while adventuring in Jackson Hole. The PlayCleanGo campaign is designed to educate and inform the public about the integral part each person can play in reducing the spread of invasive species locally and region-wide. As partners in the PlayCleanGo campaign, TCD is dedicated to working with the community to care for the natural resources of this beautiful place through preventing the spread of invasive species. Stop the spread of invasive species in your tracks by remember to:

  1. Remove plants, animals & mud from boots, gear, pets & vehicles.
  2. Clean your gear before entering & leaving the recreation site.
  3. Stay on designated roads & trails.
  4. Use certified or local firewood & hay.
