The importance of herbivore density and management as determinants of the distribution of rare plant species
Herbivores are often drivers of ecosystem states and dynamics and in many situations are managed either as livestock or through controlled or exploitative hunting of wild populations. Changes in herbivore density can affect the composition of plant communities. Management of herbivore densities coul...

Herbivores are often drivers of ecosystem states and dynamics and in many situations are managed either as livestock or through controlled or exploitative hunting of wild populations. Changes in herbivore density can affect the composition of plant communities. Management of herbivore densities could therefore be regulated to benefit plant species of conservation concern. In this study we use a unique spatial dataset of large herbivores in Norway to test whether herbivore density affects the distribution of rare red-listed plant species in tundra ecosystems, and to identify regions where herbivore density is the most important factor in determining the habitat suitability for the plant species.
