Fifty to 70 Juniperus species occur in the subtropical and temperate regions of the Northern Hemisphere (Johnsen and Alexander 1974). Most Juniperus woodlands are adjacent to various grassland communities and, in addition, are usually closely associated with small grasslands that are embedded in the woodland matrix (Baskin and Baskin 1978; Terletzky and Van Auken 1996). These glade-like areas lack an overstory and are referred to as intercanopy patches (Baskin and Baskin 1978; Breshears et al. 1997a, b; Van Auken 2000a; Ware 2002).
