Sustaining Aspen in Western Landscapes: Symposium Proceedings
USDA Forest Service Rocky Mountain Research Station
We investigated aspen (Populus tremuloides) regeneration in the Gros Ventre River Valley, the National Elk Refuge, and a small part of Grand Teton National Park, Wyoming, to see if elk (Cervus elaphus) browsing was as damaging as previously thought. We conducted a landscape-scale survey to assess aspen regeneration across gradients of wintering elk concentrations using 68 randomly selected aspen stands in the 1,090 km2 study area. Forty-four percent of the stands sampled supported regeneration of saplings (stems greater than 2 m in height but less than 10 cm in diameter). There were no significant differences of regeneration across elk winter range classification (p = 0.25) or distance from feedgrounds (p = 0.96). Our results suggest that some regeneration persists across the landscape at a variety of elk densities.
