Ascertaining Elk Impacts on Plant Communities

On the Ground
- Managers charged with managing landscapes influenced by elk are challenged to establish monitoring protocols that identify when impacts are responsible for declining ecological condition.
- We assessed the impact of elk herbivory on plant communities on an elk winter range by comparing canopy cover of common species that represented subjectively selected heavy and light elk impacts.
- Winter elk use has little direct impact on existing bunchgrasses, but winter elk traffic disrupts soils and provides the potential for invasive plant establishment.
