To help California forest property owners adapt to the changing climate, UC Agriculture and Natural Resources (UC ANR) has produced a 13-page peer-reviewed paper that outlines actions owners can take to sustain their forests' value even when temperatures rise.
“Managers of forest land have always had to adapt to changing conditions – such as markets, urban encroachment, droughts and floods,” said Susie Kocher, UC Cooperative Extension forestry and natural resources advisor. “We wrote this paper to help forest managers better understand the evolving science of climate change and how they can help their forests adapt to the climate of the...
This winter, a generous amount of rain and snow has fallen on California, but it can't erase the brown swaths of dead and dying trees in the Sierra Nevada caused by five years of drought and decades of forest mismanagement.
Fire suppression and the harvest of the largest and most resilient trees in the forest led to a large population of weak trees. The prolonged drought further weakened the trees' defenses against native insects. Aerial detection surveys show that more than 102 million trees have died since 2010; more than 62 million died in 2016 alone. Public and private landowners are now struggling to recover from this natural disaster.

To protect forests and homes from wildfire, vegetation is often removed to reduce fuel for a fire. But how do those forest management treatments affect fire risk, wildlife, forest health and water?
Since 2006, a team of University of California Agriculture and Natural Resources scientists has been studying the effects of vegetation management in the Sierra Nevada forest on fire behavior, forest health, water quality and quantity, the Pacific fisher (a small mammal in the weasel family) and the California spotted owl. The researchers are writing up their final reports and seeking public feedback on their recommendations and next steps in the process.

After academics complete fire science research, the results often end up gathering dust on a shelf. UC Cooperative Extension is now playing a significant role in bridging the gap between wildland fire science and wildland managers across the United States.
“It is a classic disconnect,” said Susie Kocher, UC Cooperative Extension advisor in the Central Sierra office. “That's why Cooperative Extension was formed almost 100 years ago. Policymakers could see that research advances weren't being implemented on farms. The same thing has happened in natural resource management.”
For example, Kocher said, scientists have known since the 1960s that systematic...
Every year, the day after Thanksgiving, Susie Kocher bundles up her children, gathers the extended family and hikes into the Lake Tahoe Basin forest to find a Christmas tree.
“It’s my favorite part of the season,” Kocher said. “Having the fresh, living thing in the house really symbolizes the holiday. You can’t do it with a fake tree.”
Kocher, a forester and the natural resources advisor for UC Cooperative Extension in the Central Sierra, lives and works in Lake Tahoe. The Lake Tahoe Basin Management District is one of nine national forests in California, all...
