In addition to Siberia and Mongolia, it is found in Kazakhstan, the Tian Shan Mountains of Kyrgyzstan, eastern Tibet, the Korean Peninsula and forested regions of northern China.

The two subspecies of the Siberian roe deer are C. p. pygargus and C. p. tianschanicus (the latter is named for the Tian Shan mountains).

It is typically up to 146 cm (4.8 ft) in body length and 59 kg (130 lb) in weight, making it larger than C. capreolus where populations from Ural and Northern Kazakhstan are the largest on average, followed by those from Transbaikal, Amur, and Primolskil regions.

In winter the northern populations exhibit light gray coloring, but their southern counterparts are grayish brown and ochraceous.

[7] Males are larger and have three-tined antlers, widely spaced and slanting upward, which are shed in the autumn or early winter and begin to regrow shortly thereafter.

[8] Siberian roe deer are found within the temperate zone of Eastern Europe and Central and East Asia.

[12][13] Denisova Cave, the famous site of the discovery of Denisovans, has also yielded fossils of the Siberian roe deer.

[18] Siberian roe deer can jump distances up to 15 m (49 ft)[citation needed], and mating occurs in August and September.
