AbstractPenetrometer soil strength and the depth of packstock hoofprints were studied in two subalpine meadows in an attempt to develop a method for determining the seasonal readiness of wilderness meadows for packstock grazing at Sequoia & Kings Canyon National Parks, California. Soil and vegetation parameters (bulk density, water content, percent gravel, sand, silt, clay, and organic matter, above-ground biomass, and below-ground biomass in two diameter size classes) were also studied in order to understand their influence on soil strength and hoofprint depth. Of the four penetrometer tip sizes tested on a Lang penetrometer, a 9/16" diameter tip was found to be a good predictor of hoofprint depth. Both 9/16" soil strength and hoofprint depth were well predicted by soil water content and meadow vegetation type.
