Quantifying Effects Of Quaking Aspen Silvicultural Treatments On Aspen Regeneration And Residual Growth, Philip W. Williams

Undergraduate Theses, Professional Papers, and Capstone Artifacts

Many quaking aspen (Populus tremuloides) populations are in decline across the western United States, a trend likely driven by ongoing climate change and past management that has led to increased competition with conifers. Restoration of aspen is a management goal potentially achievable through active forest management, but treatment effects on regeneration and residual growth have not been comprehensively studied. This project examined if removal of competing conifers altered aspen regeneration density, ungulate browsing, and residual adult aspen diameter growth using a control-impact study design. Sampling occurred at the Burnt Fork (ten treatments, four controls) and Bandy (seven treatments, four controls) …
