"Trees are poems that the earth writes upon the sky,” wrote Kahlil Gibran. But trees falling into power lines have sparked catastrophic fires and falling trees have injured nature lovers.
To prevent power outages, PG&E looks for trees near power lines that need to be trimmed or removed. To prevent power outages and other mishaps caused by failing trees, Matteo Garbelotto, UC Cooperative Extension forest pathology specialist at UC Berkeley, has incorporated science into a mobile application that can be used to determine whether a tree presents a hazard and should be removed.
“PG&E was doing tree surveys with pencil and paper,” said Garbelotto,...

Healthy California wildlands were managed with periodic wild and cultural fires for millennia. As the state's population and development grew, officials suppressed most fires out of concern for people, homes and businesses.
Though well-meaning, the strategy left land overgrown with vegetation capable of fueling even more dangerous high-intensity wildfires. The past few years have seen an exponential increase in catastrophic wildfires in California.
As a result, there is growing interest in using prescribed fire to bring nature back into balance. Despite the current interest, communities have limited capacity, shared knowledge and experience to bring it back. To close...

With a $379,785 grant from CAL FIRE, UC Cooperative Extension and the Resource Conservation District of Monterey County are spearheading a community effort to create a prescribed burn association along California's Central Coast region.
The grant is one of 55 awarded by CAL FIRE to reduce the risk of devastating wildfires that take lives and destroy homes and valued wildland environments across California.
“These 55 local projects will play a critical role in augmenting our fire prevention efforts,” said CAL FIRE director Chief Thom Porter.
Prescribed burn associations (PBAs) are made up of ranchers,...
Preventing embers from getting inside may save homes
Photos and video of the Northern California communities that have been hit by wildfires show buildings reduced to ash. How could so many homes and businesses burn so quickly in the 2017 Wine Country fires? Many houses that burned to the ground in the Northern California fires likely burned from the inside out, says Yana Valachovic, UC Cooperative Extension forest advisor for Humboldt and Del Norte counties.
Red hot embers carried on the wind can enter the attic via the venting. “In the case of the wind-driven fires on October 8, these fires created ember storms that blasted little...
The Camp Fire that destroyed the town of Paradise and other wildfires that have devastated communities in recent years have convinced wildfire experts that Californians need to take more than one approach to coexist with fire.
To better protect new houses against wildfire, California has building codes, but where residential communities are built on the landscape and how they are designed are also very important to limit wildfire-related losses, according to University of California Cooperative Extension specialists Max Moritz and Van Butsic.
“Defensible space and vegetation management is important, but in the long term, where and how we build new...
