Yellowstone Aspen Regeneration

Aspen stands in northern Yellowstone are critical in providing habitat and forage for wildlife, biodiversity, and soil stabilization. Their regeneration has long been influenced by ungulates. Historically, elk were the primary species impacting Aspen groves, but recent evidence suggests bison may now exert greater pressure, potentially limiting aspen recovery. This project seeks to understand which species are currently impacting aspen stands by expanding an existing camera-trap study from 30 to 60 plots across long-term monitoring sites. Funding for this five-year study is needed to expand efforts and collect robust data on species-specific browsing patterns and activity, informing future management and restoration strategies. Without financial support, the study’s coverage and statistical power would be reduced, slowing the ability to identify and address factors limiting aspen regeneration.
