This research was carried out by several students supervised by Dr. Art Bailey of the University of Alberta. The overall objective was to evaluate the effects of livestock grazing during the growing season, wild ungulate grazing in the winter season, and tree harvesting technology on aspen regeneration following clearcutting. Results from the study indicated that both skidding and decking disturbances reduced aspen regeneration. Wild ungulate browsing did not affect aspen regeneration. Heavy early season grazing (prior to July) did affect aspen regeneration but later, lighter grazing did not. The final reports consisted of two theses “Effects of Cattle and Wild Ungulate Foraging on Trembling Aspen Regeneration in Alberta’s Lower Boreal Forest” by Craig Dockrill, and “Effects of Timber Harvesting and Cattle Utilization on Aspen Regeneration and Forage Supply” by Cameron Lane.  An additional final report entitled, “The Impact of Cattle Browsing on the Wood Quality of Trembling Aspen in Alberta”, was also submitted by Erin Dale.
