When it comes to the spread of disease from domestic sheep to bighorn sheep, it’s not that different from the arrival of Europeans in the Americas when small pox and other diseases killed millions of indigenous people. Without a built-in immunity, pneumonia can wipe out an entire bighorn sheep herd in no time. And that’s why, last week, the Wyoming legislature passed a pair of historic bills that will effectively keep the two species apart.
In an effort to strengthen Bighorn Sheep herds in the Seminoe-Ferris Mountains near Rawlins, the Wyoming Game and Fish Department has relocated 24 sheep from Devils Canyon. Transplants from Oregon in 2009 and 2010 and from Devils Canyon near Lovell in 2010 helped establish the Seminoe-Ferris Herd, but blizzards and years of wildfires reduced the herd. Game and Fish Wildlife Biologist Gregg Hiatt joined Bob Beck to explain that the previous transplant has been a success, but they want to build on that.
