Fig. C1. Soil map associated with the area surrounding Powdermill Nature Reserve. Colored polygons indicate soil types. The vegetation survey grid is shown in black. See Table C1 for a description of each soil type.
Fig. C2. Soil map for Powdermill Nature Reserve at the block scale. Soil types for individual blocks were obtained by merging the soil survey map in Fig. C1 with the plot layout design for the vegetation survey (Appendix A). These data were used in variation partitioning model and the multivariate regression tree analysis.
