Effects of overstory stand density and fire on ground layer vegetation in oak woodland and savanna habitats

Abstract

Vegetation changes underway in oak woodland and savanna communities in the eastern and midwestern United States, primarily a result of reduced fire frequency or fire absence, include increased tree density and shading and loss of species diversity in the ground layer. However, some habitats, particularly on dry-mesic to xeric sites, retain considerable restoration potential, and insights are needed for directing management efforts, such as with prescribed fire, where they can be most effective. This paper examines overstory and ground layer interactions in flatwoods, barrens, and dry-mesic woodland habitats, together with fire effects, and highlights structural characteristics relevant to ecological condition and restoration potential.
