Fall foliage primer 1: White oak leaves
Judith and Wayne have been sharing some of their bird photos, along with interesting information, in an informal birding primer. Many of you live in areas where you don't see the full range of fall color changes that people here in the upper Midwest or the northeast parts of the country are blessed with. I decided to provide an informal occasional (not every day) primer on the primary color contributors (trees, shrubs, vines) from my area.
Fall foliage primer 1: White oak, quercus alba
This tree doesn't provide the most brilliantly colored foliage, but when it just begins to change, the spots of color among the remaining green really stand out.
A word needs to be said about the term 'white oak'. It can be used in a species specific sense, i.e. the common name for Quercus alba. It can also be used in a general sense, referring to any North American oak tree whose leaves have rounded lobes. In that sense, 'white oak' encompasses a number species, including bur oak, chestnut oak, post oak, and chinkapin. Another group of North American oaks, ones with pointed lobes on their leaves, are called red oaks, including, of course, the 'red oak', Quercus rubrum, and the 'black oak', Q. velutina, as well as pin oak, and scarlet oak. There are other native oak trees, such as the live oak, that are classed as neither white nor red. There are other characteristics, such as properties of the acorns and of the wood itself that distinguish white oaks and red oaks, but for me the leaf shape is the easiest to use.
When actual leaf color is a bit dull, back lighting livens things up a bit. I took advantage of that for these shots. Red oaks, including pin oaks, can be quite vibrantly colored. I hope to be able to share some photos of a red oak later.
