Governor Gordon Advances Sublette antelope migration corridor work

Dec. 12, 2025 

Governor Mark Gordon (R-WY) announced today that he will proceed with the consideration of the Sublette antelope migration corridor, following the recommendation from the Wyoming Game and Fish Commission to officially designate the pathway. 

“My determination is that work on the Sublette Antelope Migration Corridor will proceed, with focus on the Wyoming Game and Fish Department’s recommendation of the eight segments within the identified corridor for designation consideration, including North, Bondurant, Foothills, East of WY -191, Central, Southwest, Fontenelle, and Calpet. This decision is underscored by the best available scientific information on the value, conservation risks and opportunities detailed along these routes,” Governor Gordon said. 

The Governor’s actions follow steps outlined in the Executive Order 2020-1 (EO), Wyoming Mule Deer and Antelope Migration Corridor Protection. The Wyoming Game and Fish Commission identified the Sublette antelope corridor in March 2025, the first step in the official Corridor Designation and Review Process. The Commission voted to advance the corridor for designation to the Governor in September 2025. 

Next the Governor will appoint a local working group to analyze and evaluate the corridor. As outlined in the EO, the local working group will be composed of an appointed representative from each county affected, to include Teton, Sublette, Lincoln, and Sweetwater. 

“The Migration Corridor Conservation Strategy established by the Executive Order creates a state-led approach to support conservation for mule deer and pronghorn migration while preserving multiple-use opportunities for the State of Wyoming. I look forward to the next steps as the corridor is reviewed and elevated by a diverse local working group,” Governor Gordon said.

• The Governor has opened an application process for prospective representatives from the following groups, as detailed in the EO:

• Agriculture (2 representatives)

• Industrial users - oil, gas, mining and renewable (2 representatives)

• Wildlife/conservation/hunting (2 representatives)

• Motorized recreation (1 representatives)

The local working group is ultimately charged with reviewing the Game and Fish’s risk assessment, corridor components, potential impacts to socio-economic conditions of the region, conservation opportunities, highway projects, and other factors appropriate to the potential designation. Following their analysis, the working group will make a final recommendation to Governor Gordon, who has the authority to either designate the corridor, return the recommendation to Game and Fish for refinement, or reject the proposal for designation.

Applications for the working group will be accepted until Wednesday, Dec. 31. Following the Governor will review prospective representatives and make final appointments. Questions regarding the local working group and process should be directed to Sara DiRienzo, deputy director of policy at sara.dirienzo1@wyo.gov.
