Sambar prefer the dense cover of deciduous shrubs and grasses, although the exact nature of this varies enormously with the environment, because of their wide range across southern Asia. Home range sizes are probably equally variable, but have been recorded as 1,500 hectares (3,700 acres) for males and 300 hectares (740 acres) for females in India.
Sambar have been seen congregating in large herds in protected areas such as national parks and reserves in India, Sri Lanka, and Thailand. In Taiwan, sambar, along with sika deer, have been raised on farms for their antlers, which they drop annually in April to May and are highly prized for use as knife handles and as grips for handguns.
