Overview
A specie of wild sheep with six subspecies and another suggested subspecie. Most closely related to the North American bighorn sheep and Dall's sheep. With a chromosome number of 52 the taxonomy of snow sheep subspecies and their respective distributions requires clarification (Weinberg et al., 1997). Various Russian scientists list four to six subspecies, the Trophy Records Committee recognizes six sub species of snow sheep. In October of 2006 the committee decided to recognize the Kamchatka snow sheep (O. nivicola nivicola), and Putorana snow sheep (O. nivicola borealis) as their own sub species. Under the Siberian snow sheep (O. nivicola alleni) there are four sub species recognized in the SCI Trophy Record Book of Trophy Animals: the Koryak snow sheep (Ovis nivicola koriakorum), Okhotsk snow sheep (Ovis nivicola alleni) and the Yukutia snow sheep (Ovis nivicola lydekkeri) and Kolyma snow sheep.

Habitat
Snow sheep primarily inhabit alpine and subalpine regions, including rocky slopes, cliffs, and tundra in the mountains of Siberia and northern China. They prefer high elevations above 1,000 meters where there is sparse vegetation and escape terrain from predators. These areas experience harsh winters with deep snow, requiring adaptations for cold and wind.
Diet
Snow sheep mainly feed on grasses, sedges, shrubs, and lichens, which they graze in meadows and rocky slopes. They are primarily diurnal feeders, most active in the early morning and late afternoon to avoid the heat of the day. In winter, they dig through snow to access buried vegetation, supplementing with any available mosses or twigs.
Behavior
Snow sheep form herds of 5-20 individuals, typically consisting of females and young, while males are often solitary or in small bachelor groups. They are diurnal, spending days foraging and resting on high slopes, and exhibit territorial behavior during the rutting season in autumn. These animals are agile climbers, using steep terrain for escape and communication through vocalizations and scent marking.
Hunting
Snow sheep are a challenging big game species best hunted using spot-and-stalk methods in their alpine and subalpine habitats, requiring hunters to glass from high vantage points and navigate rugged, rocky terrain for close shots. Recommended calibers include .270 Winchester, .30-06 Springfield, or 7mm Remington Magnum for precise long-range accuracy up to 300 yards, paired with a high-quality optic and lightweight gear to handle the harsh Siberian conditions. The prime hunting season is during the autumn rut from September to October, when rams are more active and easier to locate in the mountains. Trophy criteria focus on horn length and curl, with top specimens recorded in Safari Club International (SCI), where rams with horns exceeding 100 cm are highly sought after. Legal hunting is available in Russia, particularly in Siberia regions like the Kamchatka Peninsula and parts of the Altai Mountains, through government-issued permits and guided outfits, though it's restricted in northern China due to conservation measures; always verify local regulations. Regulated hunting of Snow sheep in Russia supports wildlife management programs, with license fees funding anti-poaching patrols, habitat restoration, and population surveys, demonstrating how hunter contributions help maintain stable populations under effective oversight, similar to successful models worldwide.
Conservation Status
The IUCN classifies Ovis nivicola as Least Concern overall, though some subspecies are vulnerable due to population declines. Major threats include overhunting for meat and horns, habitat fragmentation from mining and infrastructure, and climate change affecting alpine environments.
