Table 1 Shrub cover model estimates with standard error and P-value for the main effects and interaction (treatment by years since treatment). Different letters depict significant differences in shrub cover at α ≤ 0.05. Numbers depict marginal significant levels 0.05 ≤ α ≥ 0.10. Significance codes: *** <0.001, ** <0.01, * <0.05, <0.1. Estimates (Est), standard errors (± SE), and P-values (P) are rounded to the nearest one hundredth. P-value of *** implies P-value <0.001.
