Responses of grassland production to grazing as a percentage change relative to control (%).

<p>Total biomass, aboveground biomass (AGB), belowground biomass (BGB), root/shoot ratio and litter were included in the meta-analysis. Values are means ± 95% CI and numbers of observations are shown near the bar. *The confidence intervals for the root/shoot ratio could not be calculated for the most root/shoot ratio data we collected did not have the “SD” or “SE”, but the root/shoot ratio is an essential part of grassland production, thus we still included it.
