Different species of oaks provide sprawling shelters and habitats across much of the U.S. My focus has been on Burr Oaks (Midwest), and Live Oaks (Atlantic and Gulf Coasts). Both are prominent figures in our nation’s history, offering safe campsites to pioneers, and ship planks strong enough to resist cannonballs. And both support life beyond us. Hundreds of species of animals, plants, insects and birds thrive in communities that depend on oaks.
