Appendix A (Fig. A1). Photograph from a field sampling site selected to describe mapped soil class S1 which was broadly characterized as a deep sandy soil (see Table 1 for detailed soil properties). All sites within soil class S1 were classified as the Sandy ecological site; however, laboratory analysis of subsurface texture revealed that the majority of soil class 1 sites (61.6%) were very sandy (80–90% sand to 100 cm), indicating their close proximity to a Deep Sandy designation.(USDA-NRCS 2010). The site illustrates large gaps in vegetation cover and large mesquite patches that characterized mesquite stand structure on the deep sandy soil (S1).
