Habitat
Bornean sambars primarily inhabit dense tropical rainforests, hilly terrains, and mountainous regions of Borneo. They prefer areas near rivers or swamps for water access and can adapt to secondary forests, but avoid open grasslands or heavily disturbed areas. This subspecies is endemic to Borneo, thriving in elevations up to 1,000 meters.
Diet
Bornean sambars feed on a variety of grasses, leaves, shrubs, and fruits, with a preference for young shoots and browse in forested areas. They are primarily nocturnal or crepuscular feeders, grazing during dawn and dusk to minimize exposure to predators. In human-altered landscapes, they may consume agricultural crops like bananas or rice.
Behavior
Bornean sambars are typically solitary or form small family groups, with males being territorial and using vocalizations and scent marking to defend their areas. They are crepuscular, active at dawn and dusk, spending daytime hours resting in dense undergrowth to avoid detection. During the mating season, males engage in aggressive displays and fights to establish dominance over females.
Conservation Status
The Bornean sambar is classified as Vulnerable by the IUCN due to ongoing habitat loss from deforestation and poaching. Population trends are decreasing, with major threats including palm oil plantations and illegal hunting.
