Figure 1: Map of mycorrhizal type associations in the 11 studies mountain regions. Percentage of total vegetation cover for plants associated with arbuscular mycorrhizas, ecto-mycorrhizas and ericoid-mycorrhizas, as well as non-mycorrhizal plants. For each region the total cover of plant species was recorded along multiple mountain roads as well as in the adjacent vegetation, plotted here are only the results from this adjacent vegetation independent of the road effect.
