The Shumard Oak is within the Fagaceae family and is well-suited to urban areas due to its resistance to wet and dry sites, alkaline soil, air pollution, and road salts. Every 2-4 years, the tree produces one-inch acorns that are popular among deer and squirrel diets. Able to live up to 200 years, its leaves are medium to dark green and turn a brownish-red in late fall. Despite its longevity, this tree is susceptible to several diseases and pests, including leaf spotting, blight and mites.
