Fighting Invasive Species

Protecting the biodiversity of the Tri-Canyon area.

As the result of a multi-year mapping project, CCF determined a baseline level of all existing weeds in the Tri-Canyon area and created a mitigation plan working closely with our Forest Service botanist. This map and updates have been a valuable tool in annual planning and treatments for invasive species. A window of time still exists to effectively mitigate the small sized infestations within key watershed areas to prevent further spread and damage from existing populations, whose spread is fueled by heavy recreation use.

Invasive weeds are listed as one of the US Forest Service’s four major threats to National Forest System lands nationally. Locally, the spread and strengthening of existing populations not only threaten the stability of the watershed (increased fire danger, reduced ability for the soil to hold back erosion, etc.) which provides culinary drinking water to the Salt Lake Valley, but also to the ecological integrity of the extensive biodiversity found within the Tri-Canyon area.

Presently, existing partners include the National Forest Foundation, Snowbird, the Uinta-Wasatch-Cache National Forest, Alta, the Salt Lake City Department of Public Utilities Watershed, Salt Lake County Public Works, the Utah Department of Transportation, Friends of Alta, the Bonneville Coordinated Weed Management area and, of course, our community volunteers.

Each field season, CCF hosts a comprehensive invasive weeds mitigation program in the Tri-Canyons. Continuing these mitigation efforts will continue to push back the size of the populations to a manageable size. Most of the biomass of these populations are found near the mouth of Big and Little Cottonwood Canyons, where we target our early spring weed pulls.

The key to our plan is community involvement! If you would like to get involved, e-mail our botanist, Tim Remkes, at plants@cottonwoodcanyons.org.
