In hotter, drier areas where natural regeneration is weaker, well-timed tree planting can boost post-fire forest recovery by up to 200 percent, according to research by Andrew Latimer and Derek Young, in the Department of Plant Sciences.
The extent of reduced severity of these second fires, or reburns, and the duration of the moderating effect, varies by climate, forest type and other factors. But initial fires continue to mitigate future severity even during extreme weather, such as wind, high temperatures and drought, according to research published in the journal Ecological Applications.
Restoration and resilience of California forests will benefit from the research of two graduate students whose projects have received state funding. Jennifer Cribbs and Nina Venuti are graduate students studying with Andrew Latimer, a professor in the UC Davis Department of Plant Sciences.
How long can trees tolerate drought before the forest dies?
Researchers from UC Davis can now predict which forests could survive despite future drought. Their new method links precipitation to tree growth, and it can help people decide where to put their resources as climate change affects patterns of snow and rainfall that impact the health of forests.
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.
