Subspecies: 8
1. Odocoileus h. hemionus Rocky Mountains from Yukon south to Texas and New Mexico; east to central USA and Canada. Stable.
2. Odocoileus h. crooki South-western Arizona, New Mexico, Texas; northern Mexico. Stable.
3. Odocoileus h. californicus Central California. Stable.
4. Odocoileus h. fuliginatus San Diego region in California, and lower California. Stable.
5. Odocoileus h. peninsulae Southern region of lower California. Stable.
6. Odocoileus h. cerrogensis Cedvo Islands. Stable.
7. Odocoileus h. columbianus Coastal region from central California north to Port Simpson. Stable.
8. Odocoileus h. sitkensis Coastal southern Alaska south to Port Simpson. Stable.
Remarks: It was estimated that about 10 million Mule Deer were in existence when the white man arrived; the population decreased to 500 000 in 1908 (SETON 1937). For the future it can be expected that the Mule Deer population will remain stable, provided habitat destruction can be controlled and the biotope well managed. WEMMER (1982) divides the Odocoileus hemionus into 2 groups: Odocoileus h. hemionus (Mule Deer), and Odocoileus h. columbianus (Black-tail Deer). More investigations on their status are required.
