Teton County, Wyoming, has decades of community-led efforts, to plan for and create opportunities that improve safety and permeability of roads in critical wildlife habitat. Teton County is part of the Greater Yellowstone Ecosystem and encompasses Grand Teton National Park, the National Elk Refuge and much of the Bridger-Teton National Forest, with 97% of the county in public lands. The county is home to a full suite of native large mammals, including moose, elk, and grizzly bears. Over 300 large animals are hit and killed annually on highways within Teton County Wyoming. Natural resources and wildlife are some of the strongest values to Teton County residents. These values are called out in the Teton County/Jackson Comprehensive Land Use Plan and are of benefit to the local economy. To date, most wildlife crossings projects in the area have been initiated through opportunities on highway reconstruction projects led by the Wyoming Department of Transportation. Local advocacy to make wildlife crossings a priority and develop the space for collaboration between non-governmental organizations (NGO’s) and agencies resulted in the Teton County Wildlife Crossings Master Plan that was adopted by local elected officials in 2018. This plan used wildlife movement and collision data, collected through collaborative projects of various agencies and NGO’s, to identify and prioritize locations for aquatic and terrestrial passage. Community leaders and NGO’s, working with county officials, next sought funding opportunities to address priorities identified in the plan. In 2019, Teton County voters passed a ballot measure to fund wildlife crossings through a Specific Purpose Excise Tax, in the amount of $10M. Teton County staff is now using these funds to plan and construct wildlife crossings. Highway right-of-way in Teton County is very limited, with unique stakeholders, public/private land consultation considerations, and complex topographic and geologic limitations, requiring a detailed design planning process, partnerships, and stakeholder involvement. County staff continue to work closely with stakeholders, non-profit organizations, landowners, and state and federal agency partners to develop consensus around highway mitigation solutions. This discussion will detail the successes, share lessons learned, and preview the future direction of locally led wildlife crossing projects in Teton County.
