Summary
[edit]| Description |
Quercus kelloggii— California black oak. Probably the most valuable of all California trees for the wildlife of the state. California black oak provides shelter and food for hundreds of species of birds, mammals, reptiles, and other forms of life. The species grows throughout most of California and into Oregon and Baja California, except for the Great Valley and desert regions. It can be found from near sea level to about 2700 meters. Wind-clipped specimens are sometime regarded as a form as are stunted shrubs caused by edaphic and environmental reasons. Once a widely harvested hardwood timber tree, production has declined dramatically because of over-harvesting as well as U. S. Forest Service policy throughout much of the early 20th century that regarded Q. kelloggii as a "weed" tree to be girdled or otherwise destroyed in coniferous forest. Photographed at Regional Parks Botanic Garden Located in Tilden Regional Park near Berkeley, CA. |
