Geostatistical Patterns of Soil Heterogeneity Around Individual Perennial Plants

1) Univariate, multivariate, and geostatistical techniques were used to quantify the scale and degree of soil variability around individual perennial sagebrush (Artemisia tridentata ssp. vaseyana) and bluebunch wheatgrass (Pseudoroegneria spicata ssp. spicata) plants. This variability was then compared to that found across the larger sagebrush-steppe site. Samples were taken every metre in a 10-m × 12-m grid and every 12.5 cm in nine nested 0.5 m × 0.5 m grids containing at least one Artemisia shrub or Pseudoroegneria tussock (362 total samples)
