Figure 7

Summary of meta-analyses of vegetation responses to reindeer herbivory. Subdivisions are based on groups and aspects of vegetation. Positions and widths of the diamond-shaped symbols indicate means and 95% confidence intervals of effect sizes. A position to the left of the green zero line indicates that the cover, biomass or abundance of vegetation is lower at high exposure to reindeer herbivory than at low exposure, and vice versa. Symbols not intersected by the zero line represent statistically significant effects (p < 0.05). Overall models combine data on cover, biomass and abundance. Individual data are presented in forest plots in Additional file 6
