Regressions between vascular plant cover and biocrust cover at large scales, with open symbols showing the relationship between Artemisia tridentata shrub cover and biocrust cover (R2 = 0.66; n = 20; P < 0.001) and closed symbols showing the relationship between herbaceous cover and biocrust cover (R2 = 0.32; n = 20; P < 0.001).
