Cover is usually in the 40% to 60% range. The sod is more broken and the surface somewhat more eroded around the clumps of sod. The community with the presence of the Stoneham sandy loam, but blends to some extent into the Bouteloua-Andropogon Community where the sand content is somew at ess. owever, in most places, as stated before, the boundary is quite abrupt and certainly more abrupt than most community boundaries. shrub areas is mu form a multi-dimen um which, in print ween alpine tundra primary difference ch more gradual and sional, iple, is much like and sub-alpine between the shrub areas and this community is the presence of shrubs. This is particularly true of the boundary between the Bouteloua-Muhlenbergia Community and the oute oua- ercocarpus Community. The understory of the atter is qua ttattvely similar to the species composing the former. Of course, quantitative differences are apparent but the variance within each unit is probably greater than the variance between the units.
