In 2003, Berger authored a paper<\/a> provocatively titled, \u201cIs it acceptable to let a species go extinct in a national park?\u201d That came at a time when<\/a> then-Wyoming Gov. Dave Freudenthal was wary about protecting the southern reaches of the corridor \u2014 a hesitation shared by Sublette County elected officials and the Bureau of Land Management. Safeguards for the migrating pronghorn stalled except in the northern portion of the corridor, where in 2008 the U.S. Forest Service protected some 47,000 acres via a Bridger-Teton National Forest plan amendment.<\/a>\u00a0\u00a0<\/p>\n Very slowly, times changed. A continued push to conserve the perilous passages animals encounter<\/a> along a route dubbed the Path of the Pronghorn overcame inertia and skepticism.\u00a0\u00a0\u00a0<\/p>\n This week, Berger was enthused to see Wyoming reach the penultimate step of a state-led process for protecting the route. A Gov. Mark Gordon-appointed working group completed its review<\/a> of the migration corridor, agreeing to recommendations soon headed for the governor\u2019s desk.\u00a0<\/p>\n \u201cWyoming sometimes leads, and Wyoming sometimes lags way behind,\u201d Berger told WyoFile. \u201cIt\u2019s really nice to see Wyoming, after a quarter of a century, step up and formally declare how important migration corridors are.\u201d\u00a0<\/p>\n In Pinedale, where the 11-person stakeholder group convened Friday, audience members shared their appreciation for a process that\u2019s almost done.\u00a0<\/p>\n \u201cI know it doesn\u2019t feel like it \u2014 working through Google Docs in real time \u2014 but this is actually a historic moment,\u201d Wyoming Outdoor Council staffer Meghan Riley told the working group. \u201cThis is the first time that the state has ever gone through the full designation process under the executive order. And it\u2019s the very first time the state has ever tried to do this for pronghorn.\u201d\u00a0<\/p>\n \u201cI hope you can all pat yourselves on the back,\u201d she added, \u201cand feel good about tackling this.\u201d\u00a0<\/p>\n Green River resident Bill Ames, a retired land surveyor who\u2019s been a spokesman for the migration<\/a>, was also effusive. He praised a plan that\u2019s particularly permissive of development<\/a> and \u201cisn\u2019t going to hurt\u201d economically, yet still protects an \u201ciconic species of Wyoming.\u201d\u00a0<\/p>\n \u201cWhat an achievement,\u201d Ames said. \u201cI had no expectation that this would come out this way, this fast, with a very diverse group. Thank you.\u201d\u00a0<\/p>\n Division over designating the corridors used by the highly migratory Sublette Pronghorn Herd has been a through line of the protracted process. Over seven years ago, extractive industries, counties and agriculture-oriented groups coalesced to halt<\/a> Game and Fish\u2019s first attempt to protect the landscapes the herd migrates through. In the aftermath, Gordon introduced, via an executive order, a new migration policy<\/a> that created the process with the working group.<\/p>\n The process culminates in a decision by Gordon or a future governor.\u00a0<\/p>\n Sara DiRienzo, Gordon\u2019s deputy policy advisor, explained to the working group that she\u2019d be cleaning up the final set of draft recommendations<\/a> that members fine-tuned on Friday and would give them one more chance to catch typos and make small changes. Then, she said, they\u2019d get presented to the governor \u201cfor his review and decision.\u201d\u00a0<\/p>\n Some resistance to designating the migration corridor remained from industries and counties until the end.\u00a0<\/p>\n At the onset of Friday\u2019s meeting, working group member and Sublette County Commissioner Lynn Bernard clarified that his elected body still had reservations about designating<\/a> the route.\u00a0\u00a0<\/p>\n \u201cThe position of the county [is] we\u2019re thankful, but we\u2019ll control our own county,\u201d Bernard said.\u00a0<\/p>\n Ultimately, however, none of the 11 working group members voted completely against the idea of designating the migration corridor.\u00a0<\/p>\n One member, oil and gas industry representative Jasmine Allison, voted to let the\u00a0 designation go forward with \u201cserious reservations.\u201d Two others, agriculture industry representative Mike Henn and mining industry representative Craig Rood, voted to designate \u201cwith reservation.\u201d The other eight members were fully on board.\u00a0<\/p>\n The Wyoming Game and Fish Department has not yet formally announced what mule deer or pronghorn migration is next in the queue to go through the state\u2019s designation process. There are dozens of known, mapped routes<\/a> to choose from. <\/p>\n![\"\"\/](\"https:\/\/www.newsbeep.com\/us\/wp-content\/uploads\/2026\/05\/Brimeyer-with-pronghorn-in-1998.jpg\")
