While much of the 2019 Tahoe State of the Lake Report is about the lake itself, it also addresses the severe defoliation that many aspen stands are facing due to white satin moth. Information on other UC Davis tree loss and restoration research in the Sierra Nevada and other forests is cited.
Thinning forests and conducting prescribed burns may help preserve trees in future droughts and bark beetle epidemics expected under climate change. Thinning and prescribed fires reduced the number of trees that died during the bark beetle epidemic and drought that killed more than 129 million trees across the Sierra Nevada between 2012–2016.
