The Status of Quaking Aspen (Populus tremuloides) in the Sierra Nevada
Quaking aspen (Populus tremuloides) is the most widespread tree species in North America. It provides great benefits where it occurs as forage and habitat for wildlife. It also acts as a fuel break and retains much more water in the environment than do most conifer species.
- To review the literature on quaking aspen in the western U.S.
- To elucidate the potential effects of climate change on aspen
- To provide land managers the tools with which they can monitor, understand, and potentially restore aspen stands on the landscape.
Application of Research Results
This report also summarizes the latest research on sudden aspen decline, or SAD, a climate-related phenomenon that is affecting the interior west of the United States but has not yet been seen in California. In consultation with aspen experts, we developed a survey in order to establish baseline health of trees and potentially detect the early arrival of SAD in California. The links below provide information for land managers to begin to understand the potential effects of climate change on quaking aspen.
