How to Identify Oak Trees in West Kentucky
Western Kentucky is home to nine native oak species, among them the bur oak, the white oak and the shingle oak. These trees differ in size, leaf shape, acorn shape, and size and shape of twigs. Learn to tell Kentucky's native oaks apart by these minute differences, then choose the best oak tree for your yard based upon your research, or teach oak identification to young children with an interest in science and nature.
Note the shape, texture and color of the tree's leaves to determine whether you've found an oak tree, first of all. Oak tree leaves are thick and glossy on top. They have long fingers that resemble a hand spread out. Dark or olive green throughout the year, oak leaves turn a dull brown or golden in fall.
Look for acorns to confirm that you have found an oak tree. If it's late in the fall and the tree's leaves have fallen, check the ground for acorns to help you confirm you've found an oak tree.
Examine the shape of the oak leaf. White oaks have soft rounded points while red oaks have sharp points. Knowing whether the tree belongs to the red or the white oak family will help you narrow down the possibilities from Kentucky native oak trees.
Review the images of mature trees compiled on the University of Kentucky's website and the closeups of leaves and acorns on Vanderbilt University's website to identify which of west Kentucky's nine native oak species you've located.
Identify Oak Trees
With over 600 species of oaks located across North America, Europe, North Africa and Asia, identifying one particular species from another can be a challenging task. One thing you can identify based on leaf shape is the leaf group, meaning whether the tree is a red or white oak. If you are trying to identify an oak during winter or fall, you might also be able to identify whether the leaves change color and fall off or if the tree is an evergreen variety. It's worth noting that although leaf shape alone is rarely enough to identify a tree's species, there are a handful of oaks with very distinctive leaves that can accurately result in the identification of the tree with no other information. An example includes the endangered maple-leaf oak of Western Arkansas that has deeply lobed leaves that resemble maple tree leaves more than they resemble most other American oak leaves. Almost all oaks can be classified into one of these varieties. For example, live, chinkapin and overcup oaks are all white, whereas black, pin and cherrybark oaks are all red. Red oaks take two years to reach maturity and produce acorns consistently year round. Sometimes you not only need to look at your location geographically but also the habitat.
To make it easier on yourself, identify oak trees in late spring once the trees have put out leaves. Once you've become skilled at tree identification, try to identify western Kentucky oak trees by their twigs in early spring.
