Potential limitation to tree health and growth for each of the RUSI parameters. The lower the rank, the more limiting that parameter was expected to be for tree growth and health based on expert opinions and professional experiences of the primary investigators. Precipitation (PPT), growing degree days (GDD), exposure (EXP), traffic (TRA), infrastructure (INF), surface (SUR), estimated rooting area (ERA), penetration (PEN), A-horizon (HOR), texture (TEX), structure (STR), wet aggregate stability (WAS), soil organic matter (SOM), electrical conductivity (EC), and pH.
