White oak trees serve as a critical foundation for both the ecosystem and economy across the Upper Cumberland.
That’s why the state is taking steps to sustain the tree. Jackson County Extension Agent Dill Hughes said white oak acorns are a highly preferred nutritional food source for white-tail deer, wild turkeys, bears, and hogs.
“The oak is a highly desirable firewood too,” Hughes said. “It’s a very very good hot burning firewood, and it stores well, and it burns well, and it lasts a long time when it’s burning where some of the other softer type woods burn up much quicker and doesn’t put out as much heat for as long a period of time.”
The tree is one of the most economically significant hardwoods in the region alongside red oak, black walnut, and black cherry. The state began a statewide acorn collection program to support white oak forest regeneration efforts last week.
The durability of the wood also makes it a top choice for flooring and furniture manufacturing. The species is uniquely suited for whiskey barrels because its internal structure prevents liquids from passing through the wood, unlike red oaks which allow liquid to travel across the cross-section.
The species faces long-term challenges with natural regeneration because it is slow-growing and frequently overshadowed by faster-developing species. Because it takes approximately 60 years for a white oak to reach maturity, many landowners choose to prioritize trees that offer a quicker financial turnaround.
“Landowners and homeowners and people that own property they don’t always think about the value of their timber because it’s not a yearly return, and so White Oaks don’t get planted a lot of times because they’re not a quick turnaround,” Hughes said. “Pines get planted because they are a quick turnaround they can be thinned in about 15 years after planting, and you can get some income from that. But long term the native hardwoods like the red oaks and white oaks and some of the others that we have out there, it just takes them a long time to grow and produce and get to where they need to be.”
Property owners can improve annual crop yields by removing competing trees from around the perimeter of a healthy canopy to allow more sunlight to reach the crown. Landowners with at least 15 acres can coordinate with the Tennessee Division of Forestry to secure a professional land assessment.
“Reap the rewards and benefits from the work you do on your property,” Hughes said.
