According to Douglas Tallamy (author of Bringing Nature Home), oak trees are the single most important plant to grow if you want to support animal diversity. Oaks support over 500 species of moths and butterflies (which, in his studies serve as a proxy for all insects). In addition, its nuts provide food for a number of small mammals.
So why the White Oak (quercus alba)? Well first, it is a beautiful, majestic tree that has beautiful color in fall. It is the Maryland State Tree and many Maryland gardeners are familiar with Maryland's most beloved tree, the Wye Oak, over 450 years old when it was felled by a storm in 2002.
As for growing conditions - first, the White Oak needs room. It will grow to 75-100 feet tall, with a spread the same size. It does well in sun or part shade and does not need a lot of moisture.
These are fairly slow growing trees and they have a long-tap root, so it is best to transplant them when they are small. A lot of traditional nurseries do not sell oaks, but they are available at native plant nurseries. Here is a source of a seedling from the Wye Oak.
Even if a white oak is too big for your yard, consider some of the smaller oaks like bear oak (quercus ilicifolia) or blackjack oak (quercus marilandica).
