Grant money has been awarded to the Nez Perce Tribe of Idaho to buy collars for bighorn sheep. The tribe's wildlife program received $200,000 from the U.S. Department of Fish and Wildlife. The number of bighorn sheep along the Snake River keep dropping lower, lambs are not making it to adulthood. The tribe's wildlife program will collar more ewes, hoping to find the lambing grounds. This will help find the lambs sooner after they die and help researchers determine the cause of death.
The U.S. Forest Service and Bureau of Land Management will then know if they need to change land management for domestic sheep. Bighorn sheep may contract pneumonia and other diseases from domestic sheep, if this is what is killing off the lambs there will need to be a bigger separation from the wild and domestic. Last year domestic sheep grazing was reduced by 70%. Bighorn sheep population is down 50% from 1990, from Deseret News .
