Ecology and life history

As a rare, endemic mammal on a relatively secluded island, the ecology of the tamaraw is largely unknown. Individuals of the species are reclusive and shy away from humans. In addition, the small sizes of the species' subpopulations, already spread thin throughout their fragmented range (on 1986, about 51 individuals are found in a 20 square kilometer area),[12] make contact with any more than a solitary individual a rarity.

Habitat

Bubalus mindorensis prefers tropical highland forested areas. It is typically found in thick brush, near open-canopied glades where it may graze and feed on grasses. Since human habitation and subsequent forest fragmentation of their home island of Mindoro, the habitat preferences of the tamaraw have somewhat expanded to lower-altitude grassy plains. Within their mountainous environment, tamaraws will usually be found not far from sources of water.[3][8] They have to live by water so they can drink. They live in moist areas such as, marshy areas, and grasslands.

Trophic ecology

The tamaraw is a grazer that feeds on grasses and young bamboo shoots although it is known to prefer cogon grass and wild sugarcane (Saccharum spontaneum). They are naturally diurnal, feeding during the daytime hours; however, daytime human activities have recently forced select B. mindorensis individuals to be nocturnal to avoid human contact.[4]

Life history

The tamaraw is known to live for about 20 years, with an estimated lifespan of about 25. The adult female tamaraw gives birth to one offspring after a gestation period of about 300 days.[13] There is an interbirth interval of two years, although one female has been sighted with three juveniles. The calf stays for 2–4 years with its mother before becoming independent.[4]
