CAN BE FOUND IN:

Garry Oak

Quercus garryana

Appearance

The Garry oak is a deciduous tree with large craggy branches. It grows to 25 metres tall and has shiny, green leaves and light grey bark with thick ridges. 

Range & Habitat

The Garry oak is found along the west coast of North America from southern B.C. to mid-California. It is the only native oak growing in B.C. (it is leftover from before the Ice Age). It is common on open and dry sites, and forms a special meadow ecosystem with camas, shooting star, arbutus and other plants. In B.C., this plant is found in the Georgia Depression ecoprovince. 

Reciprocal Relationships

The Garry oak is a slow-growing tree. The leaves of the oak turn dull yellow or brown in fall and produce small acorns. Many beings eat these acorns, including humans if they are roasted or steamed first. Birds, small mammals, and insects make their home in these trees.  

This tree is indicative of the Garry oak ecosystem, and while the species itself is not endangered, the ecosystem is. These grassland areas are home to the greatest variety of plants and animals out of any other ecosystem in coastal British Columbia. These ecosystems are important to protect and study due to their drought tolerance. However, they are at-risk due to wildfire suppression, land development, and invasive species.  

Lekwungen-speaking First Nations regularly care for this tree and the ecosystem through intentionally burning meadows. This would prevent other trees and shrubs from entering the ecosystem and help to manage bigger fires.
