There are 26 species of oak that are native to Oklahoma. At least 21 of these species occur in eastern Oklahoma. In addition, there are many ornamental oaks that are also found in the state. Possibly the two most important species in the region are post oak and blackjack oak. These define the botanical community of eastern Oklahoma. Pin oak, water oak, red oak, and black oak are used extensively in landscaping. We will present only a small sampling of the many oaks within the state.
