UC ANR hires more fire advisors to address growing threat to California communities
Bringing more expertise to more places across the state, University of California Agriculture and Natural Resources continues to hire fire advisors to help communities prepare for one of the most devastating climate-fueled threats.
With wildfires a constant danger as drought grips California, three highly skilled UC Cooperative Extension advisors have joined the organization since early May: Luca Carmignani, serving Los Angeles and Orange counties; Barb Satink Wolfson, serving...

UCCE forest advisor helps landowners, community groups determine best project options
As Californians prepare for another year of drought and an anticipated intense fire season, landowners and organizations across California have been working to reduce forest fuels – flammable woody material – that can endanger their properties and communities.
For many of them, however, their urgent efforts hit a sizable speed bump: a massive rulebook that describes, amid a thicket of other information, the permits required before people can treat or remove fuels – as well as a litany of attached requirements, restrictions and...

Results help inform best practices for managing the disease-causing beetle
The University of California, Irvine campus is home to a vast urban forest consisting of approximately 30,000 trees located in a mix of landscape, riparian and open space settings. In the mid-2010s, that forest came under threat from an invasive species of beetle that arborists and pest researchers were just learning about – the polyphagous shothole borer.
The tiny beetles, which may have arrived in California from their native Southeast Asia via infested shipping materials, tunnel into trees and introduce a fungus that serves as food...

Pilot program in Santa Barbara County shows promise for bolstering resilience
After a rash of wildfires across Southern California in 2003, many counties, cities and neighborhoods adopted Community Wildfire Protection Plans to improve their preparedness and fire response. But Rob Hazard, fire marshal for Santa Barbara County, has noticed that CWPPs and resources are unevenly distributed across areas at high risk of wildfire.
“Communities that are more affluent, more white, they are the ones that end up getting the grants, they're the ones that end up getting the projects to mitigate risks,” Hazard said, “whereas more disadvantaged...

Wildfires burning in western U.S. forests have increased in size and severity since the late 20th century, with a number of recent fires exhibiting characteristics that match the criteria for mass fires – or fires that burn with high intensity over large continuous areas for long durations of time.
Operational fire behavior models, commonly used by federal and state fire suppression agencies to predict how wildfires will behave, cannot predict mass fire behavior, largely because they do not include the important combustion and fire-atmosphere interactions. The Creek Fire, which exhibited mass fire behavior when it burned through the southern Sierra Nevada in 2020, was...
