Mean effect sizes and 95% confidence intervals (lnRR; pre vs. posttreatment cover) for perennial grass (A), perennial forb (B), annual grass (C), and annual forb (D) vegetation responses following pinyon–juniper reduction in three sagebrush community types (i.e., black sagebrush (Artemisia nova), Wyoming big sagebrush (A. tridentata ssp. wyomingensis), and mountain big sagebrush (A. tridentata ssp. vaseyana)) when treatments are both pooled or separated (solid black circles). Overall effects (blue diamonds) indicate effect sizes for all observations; values in parentheses are the number of observations used to calculate effect sizes. Effect sizes are considered significantly different from one another if confidence intervals do not overlap.
