The Post Oak: Quite the Contributor

Post oaks aren’t as celebrated as white or live oaks, but they’re important contributors to the forest food web and human society.

Being members of the white oak group, post oaks produce (relatively) palatable acorns that are popular with birds, deer and the other usual suspects. And while they are smaller than some other white-group acorns, they serve as an important food source in some places.  

Humans, on the other hand, celebrate the tree for its strong, durable wood. In fact, it gets its common name from its use in making fence posts. It’s also used for other demanding applications like stairways and rail ties.

Identification: Tips & Tricks

The post oak’s leaf is reasonably distinctive, and a “classic” example of a leaf is pretty easy to identify. Just look for the five-lobed, somewhat cross-like shape, along with the absence of bristle-tips. However, the leaves of this tree also quite hairy or rough (often being described as “sandpaper-like”) – especially on the top surface.

It often bears twisted, gnarled branches at the lower levels of the canopy, but it’s rarely necessary to go beyond leaf shape and texture to identify this tree.
