VERY GOOD
Oregon white oak is found in Oregon and Washington, Q. lobata only in California. They are very similar in appearance and durability as a bearing tree. Unfortunately they grow intermixed with the black oaks and the original surveyors did not distinguish them, calling all "oaks". The white oaks have rounded lobes, the black oaks toothed lobes on the leaves. The white oaks are slow growth, decay resistant and reach ages of 500 years or more.
When found the white oak is usually completely healed after SO years or so. The blaze may not be apparent, except by closely observing the difference in shading of the bark.. White oaks have been round with over :l2" of over-growth over a perfectly healed blaze. The "whorly grain" may disappear after only 3" or 4" of overgrowth, so don't stop to soon when opening a suspected bearing tree. After being cut down the stumps decay rather rapidly and sometimes only a shell remains. There is usually a pronounced stump hole.
Select young trees, 8" to 10" diameter. Keep the bottom of the blaze at the root crown well drained and smooth at the edges to avoid separating bark from cambium layers. Paint thoroughly. Do not bark scribe.
