418 White spruce/juniper/little bluestem savanna This alvar vegetation occurs in the Great Lakes basin of the northern US and southern Ontario. The structure is variable, ranging from open outcrops, grasslands or shrublands, to woodlands. Typically alvars are mosaics of these conditions based on soil development. Alvars are often composed of mixed grasslands with sparse overstories of white spruce, northern white-cedar, or jack pine interspersed with shrublands of juniper and other shrubs that thrive on calcareous soils. 210,220 5 4 401 18 2 1
