Oregon white oak (Quercus garryana)

Description

“Pet poisonous” – Toxic parts: shoots, leaves Quercus garryana, the Garry oak, Oregon white oak, Oregon oak, or Hu'dshnam, from the traditional Klamath language, is a tree species with a range stretching from southern California to southwestern British Columbia. It grows from sea level to 210 meters (690 ft) altitude in the northern part of its range, and at 300 to 1,800 meters (980 to 5,910 ft) in the south of the range in California. The tree gets one of its names from Nicholas Garry, deputy governor of the Hudson's Bay Company, 1822–35. In British Columbia, the Garry oak grows on the Gulf Islands and southeastern Vancouver Island, from west of Victoria along the east side of the island up to the Campbell River area. There are also small populations along the Fraser River on the British Columbia mainland. The northernmost population of Garry oak can be found just below 50°N on Savary Island, in the northern stretches of the Straight of Georgia. In Washington state, the garry oak grows on the west side of the Cascade Range, particularly in the Puget Sound lowlands, the northeastern Olympic Peninsula, Whidbey Island, the Chehalis river valley, and the San Juan Islands. It also grows in the foothills of the southeastern Cascades and along the Columbia River Gorge.
