Figure 6. Relationship between ruderal species richness (left: total, right: non-native only) and elevation on two mountain trails. Left n = 39, right n = 12). Björkliden (in red) and Låktatjåkka (in blue) mountain trails, trendline in gray as no significant difference between both trails was observed. One dot is the species count at a certain elevation and hiking trail. Model coefficients are shown in supplementary Tables 10-11.
