Assessing The Efficacy Of Beaver Dam Analogs In Willow Restoration, Hannah Hill, Dylan Ritter
Undergraduate Theses, Professional Papers, and Capstone Artifacts
Willow establishment is a necessary objective of stream restoration due to their role in bank stabilization, stream shading, and enhancement of biodiversity across the riparian zone. However, anecdotal observation indicated that establishment on beaver dam analogue (BDA) restored streams may be lacking. BDA’s mimic the pooling effects of natural beaver structures and are intended to help recreate historic conditions that existed before beaver extirpation. When working as intended, ecosystem function is restored, and a major aspect of this is willow presence. Because of these observations, as well as limited information on willow recruitment following restoration, we ask the following questions. …
Quantifying Effects Of Quaking Aspen Silvicultural Treatments On Aspen Regeneration And Residual Growth, Philip W. Williams
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) …
