Do you think the you have the largest White oak tree in Warren County, OH? Enter to win our Biggest Tree Contest!

White oak (Quercus alba) is arguably the most important wildlife tree in Ohio. Oaks support more forms of life — birds, mammals, insects (including moths and butterflies) — than any other class of tree. White
oak acorns provide a vital food source for animals like deer, turkey, and black bears. They provide critical habitat for birds like the imperiled cerulean warbler, and for endangered bats like the Indian bat. As the longest-lived and most durable of the eastern oaks, white oaks can provide ecosystem and habitat stability for centuries!

White oaks can be identified by their light-colored, flaky bark, rounded leaf lobes, and acorns that ripen in one growing season. The bark is often described as ashy gray or even almost white, with a scaly, plate-like texture. Leaf lobes are rounded, not pointed, and the acorns are medium to large with a cap covering about a quarter of the nut.
