The sable, a species of marten, is prized for its fine fur, which along with ginseng and deer antler velvet, are known as the "three treasures of Manchuria."

The beech marten of western China and yellow-throated marten of southern China are closely related to the sable.

American marten are trapped for their fur in all but a few states and provinces where they occur. The highest annual take in North America was 272,000 animals in 1820. Trapping is a major source of American marten mortality in some populations and may account for up to 90% of all deaths in some areas. Overharvesting has contributed to local extirpations. Trapping may impact population density, sex ratios and age structure. Juveniles are more vulnerable to trapping than adults, and males are
