Aspen Restoration
Quaking aspen stands provide ecosystem services such as enhanced landscape-scale fire resilience, improved water quality, and increased water retention. Despite comprising less than 1% of forests in the Sierra Nevada, aspen habitat bring outsized biodiversity benefits by adding complexity to the landscape and offering high-quality forage for a variety of species.
Aspen have been in decline on the western slope of the Sierra Nevada due to fire suppression, climate change, intensive grazing practices, hydrologic changes, and increased infrastructure. Restoration can be used to promote aspen regeneration to prevent further decline and loss. Aspen stands provide high elevation habitat for aquatic species, migratory birds, and terrestrial wildlife with a wetted landscape and high quality forage. With increasing periods of drought, aspen stand restoration is imperative to increasing resilience to climate change.
