Interaction effect on the evenness (EShannon) of plant species in the landscape. In landscapes with no power line corridors, an increase in road verge density has a negative effect on the abundance distribution of plant species. In contrast, in landscapes with power line corridors, an increase in road verge density has a positive effect on the abundance distribution of plant species. Grey bars represent the 95% confidence intervals. The silhouette image was available under Public Domain license at PhyloPic (http://phylopic.org).
