Appendix C. Soils Survey Data.

Table C1. Description of the 21 soil types found at Powdermill Nature Reserve, obtained from publicly available survey records. Typical physical and chemical properties for each soil type are shown, and were obtained from detailed descriptions of the soil types available from the web soil survey (NRCS 2013).

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.


 

FigC2

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.
