(Mike Koshmrl/WyoFile)As the days shorten and temperatures drop in the weeks and months ahead, the same animals will likely be headed south from their summer range near the Prospect Mountains to their lower-elevation winter range near U.S. Highway 191 down toward Rock Springs. Unbeknownst to the fleeing pronghorn, they’d recently been the subject of a political dispute. Their migration routes, known as the “East of Farson” segment, were in line to be excluded from protections under Wyoming’s migration policy. The Wyoming Game and Fish Commission, however, put the kibosh on that plan, voting that the “East of Farson” and Red Desert pronghorn ought to be included and protected.
