a,b, Density (a) and aboveground dry biomass (b) of mimosa per hectare in the control and herbivore-exclusion plots in August 2018. The box limits represent the interquartile range, whiskers the minimum and maximum, centre lines the median, white dots the mean, and black dots the value for each of n= 6 plots in each treatment. Within 3 years of the experiment, mean mimosa density was nearly 15-fold greater in the absence of LMH (641 individuals ha−1 in the control plots versus 9,385 individuals ha−1, roughly one plant m–2, in the exclosures), and mean mimosa biomass was more than two orders-of-magnitude greater (2.6 kg ha−1 in the control plots versus 304.6 kg ha−1 in the exclosures). One-way ANOVA of plot-level values by treatment: density F1,10 = 5.87, P = 0.036; biomass F1,10 = 7.69, P = 0.020; n = 12 plots.
