Appendix A. Location of sites and diagram of nested sampling design.

FIG. A1. Approximate locations of the seven study sites (blocks) within the Appalachian Mountains of western Virginia and West Virginia. BB1 = Blacksburg District site 1; BB2 = Blacksburg District site 2; CL1 = Clinch District site 1; CL2 = Clinch District site 2; NC = New Castle District site; WV1 = Westvaco Corporation site 1; WV2 = Westvaco Corporation site 2.

FIG. A2. Typical layout of the experimental units within each site and arrangement of nested plots and subplots to illustrate sampling scheme. Richness of native and non-native vascular plant species was recorded at the 2 hectare experimental units (EUs), 576-m2 plots, and 1-m2 subplots. Disturbance treatment codes are included in the EUs as an example to illustrate that each treatment was randomly assigned to EUs within each site. CON = uncut control; HB = understory herbicide; GR = group selection; SW50/60 = high leave shelterwood; LV = leave tree harvest; SW20/30 = low leave shelterwood; CC = clearcut.
