Appendix B. Table characterizing each experimental site location, including the site type, year planted, soil texture, nutrient concentrations, and moisture, thermal conditions, and standing herbaceous biomass.

TABLE B1. Table characterizing each experimental site location, including the site type, year planted, soil texture, nutrient concentrations, and moisture, thermal conditions, and standing herbaceous biomass. Site type categories are as follows: (a) silty valley bottoms - cold, low-lying areas in the valles with loams or silty loams, (b) sandy backslopes – warmer mountain slopes with gravelly, sandy loams, (c) silty backslopes – shallow benches on mountain slopes with loams or silt loams that are located above the temperature inversion layer, and (d) sandy valley bottoms - cold, low-lying valley bottoms with gravelly, sandy loams such as may occur on fluvial and erosional deposits. Year refers to the year the plot was established and first planted (2002 or 2003). Sand and silt are reported as percentages of dry mass (after removal of organic matter, OM). Organic matter and nitrogen (N) are also reported as percentages of dry mass; other nutrients (P,K, Ca, Mg) are reported in parts per million. Soil moisture (H2O) is calculated as a mean percent dry mass for the period between 1 June and 1 September 2004. Mean daily maximum, mean, and minimum temperatures are averages from 1 June – 1 September 2004. Aboveground standing herb biomass is reported as grams/m2; belowground biomass is g/m3.
