Wild Sheep Initiative

“We are committed to the restoration and conservation of bighorn and thinhorn sheep for the benefit of future generations”

“To identify priority topics and management challenges to wild sheep in western North America; collaboratively develop solutions to those challenges; and foster strong relationships between state/ provincial/territorial jurisdictions, federal land management agencies, indigenous groups, and wild sheep advocates; and engage with domestic livestock owners and users that share the same landscapes inhabited by wild sheep.

Mission Statement, Revised January 2020

The Wild Sheep Initiative is comprised of a representative from each WAFWA state, province, and territory (N=20) with wild sheep, plus representatives from the U.S. Forest Service and the Bureau of Land Management, National Park Service, Tribal entities and the Wild Sheep Foundation.

WILD SHEEP FOUNDATION’S:  WILD & WOOL DOCUMENTARY

Bighorn sheep, an icon of the American West, battle to survive as contact with infectious diseases carried by domestic sheep threaten these wild herds. The respiratory pathogen mycoplasma ovipneumoniae (M.ovi), while benign in their domestic sheep hosts, can present deadly complications for bighorn sheep and often leads to widespread pneumonia outbreaks and significant die-offs. Domestic sheep grazing on public land was an integral part of settling the western United States. However, as conservation efforts ramp to rebound bighorn populations, the wool industry, scientific community, and wildlife advocates are at a crossroads. Wild & Wool had its public debut as a featured introductory film during the Wild Sheep Foundation’s Sheep Week virtual convention on January, 2021.
