How to identify the tree species.
White oak is a large tree with a long, straight trunk and a broad, rounded crown. Leaves are alternate, simple, 5–9 inches long, 2–4 inches wide; margin entire, with 6–10 lobes; lobes rounded at the tip; upper surface bright green, smooth, often shiny; lower surface whitened, smooth. Can reach heights of 50-100 fee with a massive canopy. The bark is light ash gray.
How have people made use of the trees (wood, fruit etc.).
Construction-grade products, like railroad ties or wood pallets, or high-quality materials such as flooring and veneer for cabinets and furniture
Wildlife Value:
How do animals, insects and others make use of the tree?
Many birds nest in white oak, such as the near-threatened Cerulean Warbler that spends much of its time hopping around from branch to branch feeding on insects in the canopy of mature white oaks.
Symbiotic relationship with other species?
White oak trees have developed a relationship with a specific type of mycorrhizal fungi called ectomycorrhizae to facilitate these functions. Their hyphae connect to the tips of tree roots to form a physical connection known as the mycorrhizal network which serves multiple, reciprocal roles.
