Rams have massive horns that grow over and behind the ears in a C-shaped curl. Horns are permanent and grow incrementally year by year. It may take 7 to 8 years for a ram to acquire a full curl. Ewes have a shorter, more slender horns that curve gently back.
The River Mountains are perfect habitat; for the bighorn sheep occupy rough, precipitous terrain near sources of permanent water. Bands follow regular feeding routes and maintain bedding grounds that may be used for years. The desert bighorn sheep is Nevada’s state mammal.
The sheep population in the River Mountains is estimated at 200+. In order to protect this herd of sheep the BLM has designated a good portion of the Northwest mountain range as an “Area of critical Environmental Concern” (ACEC) to help protect this productive herd of bighorn sheep. Each year to keep this herd in balance the National Wildlife Service culls the herd by capturing sheep and re-locating into other mountain ranges in Nevada and elsewhere in the west.
