Garry oak (Quercus garryana) belongs to the family Fagaceae (the Beech family). It is a tall deciduous tree that is native to western North America from British Columbia to California. This tree grows in foothills, mountains and riversides, and it can reach 12-24 m in height and 60-90 cm in trunk diameter. The tree crown is broad and round topped, consisting of many thick gnarled twisting branches. The bark is light gray to gray-brown, and furrowed into shallow irregular broad ridges. The leaves are dark green and shiny above and paler below, leathery, and pinnately lobed with 5-9 irregular rounded lobes. The fruits are light brown acorns, about 2.5 cm long, with shallow and bowl-like caps, and mature in a single season. The tree is named after Nicholas Garry, deputy governor of the Hudson's Bay Company.
