Oregon white oak (Quercus garryana) provides visual variety to landscapes, income to woodland owners, and habitat for many wildlife species. If unrestrained by over-topping vegetation or disturbance, Oregon oak grow to impressive dimensions and ages. The foliage on spreading branches of massive oak creates shady summer retreats for wildlife and people, and this tree can be an appealing sight when outlined against an evening sky or sketched on green spring fields. Prehistoric peoples fed on acorns from Oregon oak, but today it is often viewed as an undesirable species or valued mainly for firewood. Nonetheless, Oregon oak provides important habitats for wildlife. Over 140 species of wildlife including amphibians, reptiles, birds, and mammals use Oregon white oak habitats in Oregon and Washington for nesting, feeding, or resting.
