AbstractThis study compared the effects of sampling metrics (basal area, density) on community structure analyses. Additionally, an oak woodland classification system was developed from the basal area data for the southwestern United States. Minimum-variance clustering was used to define communities within the oak woodlands. The communities defined by basal area data were more evenly distributed, showed more distinct communities, and were more homogeneous than the density-based communities. Thirteen communities were identified in the classification of oak woodlands, with mean basal area varying by an order of magnitude. Elevation had a major influence on the distribution of the communities.
