Oak is a tree or shrub in the genus Quercus of the Fagaceae family. There are about 600 extant species of Oak. It is native to the Northern Hemisphere and includes both deciduous and evergreen species. The natural habitat of an Oak tree ranges from cool temperate to tropical ecosystems in America, Asia, Europe, and North Africa.

In India, Oak trees generally occur in the temperate areas of the Himalayas. The tree is a major source of fuelwood and the leaves serve as good fodder for livestock. About 32 species of Oak are found in the Indian subcontinent, including Myanmar.

Generally, locals use Oak timber for making agricultural implements in addition to fuelwood, timber, and fodder. Oak bark is also rich in tannin and is used by tanners for tanning leather. Many species of Oaks are under threat of extinction in their natural habitat, largely due to the improper usage of land and unsustainable harvesting practice. It is an evergreen tree bearing stalked, ovate to lanceolate, acuminate, serrate, leathery, and dark green leaves which are glabrous above and densely white or gray pubescent beneath. Male flowers are slender with drooping spikes. Female spikes are sessile and axillary. An acorn is solitary.
