Least-squares mean estimates (± 1 SE, n = 3) of B. eriopoda foliar cover from the mixed-model analyses for (top) grazing treatments and (bottom) grazing treatment*shrub treatment interactions. Values are relativised to the overall mean B. eriopoda cover in 1996 (black dot = 1.56%). The time periods of perturbation and recovery are noted at the bottom.
