Oak Savannas are some of the rarest ecosystems in the United States. Unlike a forest, the trees of an Oak Savanna do not form a complete canopy, and as a result, plenty of sunlight can reach the ground. These partially-shaded conditions promote a unique set of forbs and grasses as well as significant ecological complexity due to the microclimates created by differences in canopy cover. The dominant tree is Bur Oak (Quercus macrocarpa), which can fully embrace its attractive growth form in this park-like environment. Additionally, other Oaks and fire-tolerant trees like Hickories can be present.
The following information on species composition can be used for Savanna restoration and improvement, but it is also useful for planting in areas with difficult conditions that are too sunny for most woodland plants but too shady for many prairie plants.
