Wikipedia Abstract

Quercus garryana, the Garry oak, Oregon white oak or Oregon oak, is a tree species with a range stretching from southern California to southwestern British Columbia. It grows from sea level to 210 metres (690 ft) altitude in the northern part of its range, and at 300 to 1,800 metres (980 to 5,910 ft) in the south of the range in California. The tree is named after Nicholas Garry, deputy governor of the Hudson's Bay Company, 1822–35.

Usage [3]  A mulch of the leaves repels slugs, grubs etc, though fresh leaves should not be used as these can inhibit plant growth; Oak galls are excrescences that are sometimes produced in great numbers on the tree and are caused by the activity of the larvae of different insects. The insects live inside these galls, obtaining their nutrient therein. When the insect pupates and leaves, the gall can be used as a rich source of tannin, that can also be used as a dyestuff; Wood - hard, heavy, strong, tough, close grained, durable, easy to split. Used for furniture, cabinet making, general construction etc and also for fence posts and fuel;
