Dall's Sheep Species Background

  • There are four subspecies of North American wild sheep
  1. Thinhorns which consist of the Dall’s and Stone’s sheep; and
  2. Bighorns which consist of the desert and Rocky Mountain bighorn sheep.
  • More than 90 percent of North American wild sheep reside on public lands.
  • State, federal, crown land agencies as well as tribal entities play an important role in wild sheep management.
  • Disease transmitted from domestic sheep to wild sheep is the No. 1 limiting factor to successful recovery of wild sheep populations.
  • Some public lands allow domestic sheep grazing in suitable historic wild sheep habitat causing large scale die-offs with many years of poor wild sheep lamb recruitment.
