On Oct. 2, the prescribed-fire workshop will be held at Colfax Veterans Memorial Hall, 22 Sunset Circle, Colfax.
On Oct. 4, the workshop will be held at Ebbett's Pass Fire District, 1037 Blagen Road, Arnold.
The one-day workshop is designed for landowners and land managers who want to learn skills in prescribed-fire planning and implementation. In addition to reducing wildfire fuels, prescribed fire is used to control invasive plant species and for ecological restoration.
Each workshop will feature similar content including presentations on prescribed fire, including local fire history and current fire research, prescribed fire permitting and legal considerations, fire weather forecasting and online tools, air quality and smoke management, fire terms and fire behavior, burn plan development, burn unit preparation and fire tools and equipment. Instructors will also discuss models for accomplishing prescribed fire on private lands, including prescribed burn associations and CAL FIRE's Vegetation Management Program.
During the last week of October, participants in each workshop will be invited by UC Cooperative Extension to a field trip to look at lands actively managed with prescribed fire and to participate in a live training burn (weather permitting) at UC Berkeley's Blodgett Research Forest in Georgetown in El Dorado County.

California is a place forged by fire, and its fierce fire-fighting policies are creating fuel-filled landscapes that will burn hotter and faster than ever, reported Lisa M. Krieger in the San Jose Mercury News.
"Unless we change course, we'll never work our way out of this dilemma," said UC fire scientist Scott Stephens. "Unless we can get ahead of it, it'll never get better."
Strategies to live with fire were modeled at the UC Hopland Research and Extension Center when the Mendocino Complex Fire spread on its rolling oak woodland and chaparral landscape in late July. About 3,000 of the center's 5,300 acres burned.
In pastures where sheep had grazed, the oaks still have green leaves. In other areas not grazed since the 1950s, undergrowth provided a ladder for flames to reach oak canopies.
In areas were vegetation was reduced by grazing, "the fire was less intense. It skipped around more. It wasn't as complete a burn," said Hopland director John Bailey. "Having animals on the land reduced the hazard."

Prescribed burning is another strategy to maintain a forest that is resilient to fire.
“Prescribed burns are a really powerful and underused tool,” said UC Davis ecologist Malcolm North. When a wildfire hits pre-burned areas, “it just putzes along.”
Even after wildfires have burned homes and taken lives, communities allow for rebuilding in wildland-urban interface areas prone to such disasters, reported Alistair Bland in the East Bay Express.
Van Butsic, a UC Cooperative Extension specialist at UC Berkeley, has studied the alarming trend of building homes in known fire-risk areas.
"We studied 30 of the largest fires since 1970," he said.
On average, 20 years after an inhabited area burns, most of the destroyed homes are rebuilt and many new homes were added — about twice as many homes in total as there were at the time of the burn.
UCCE forestry and natural resources advisor Sabrina Drill said people seem to have short memories.
"I (would) think people might think twice about building a home where there had just been a fire, but people seem to forget after about three years," Drill said.
Drill, Van Bustic and other UC Agriculture and Natural Resources scientists were sources for the nearly 5,000-word East Bay Express story about the hazards to people and property in the wildland-urban interface and ways to manage the problem in a state where climate change appears to be making wildfires more frequent and intense.
The article said most fire experts and community leaders believe not enough is being done to prevent catastrophic blazes. They want more prescribed burning to reduce fuel loads, increased funding for firefighting and wildfire research, and stricter controls on development in wooded areas.
"But that's so politically contentious — it's a line politicians walk up to but turn away from," said William Stewart, a UCCE forestry specialist at UC Berkeley.
He said society tends to be concerned about wildfires during and immediately after high-profile catastrophic events. However, the attention is often short-lived and doesn't generate change before the next fire strikes.
"It's surprisingly hard to get investments in fire prevention strategies, even after the scale of the fires we just had," Stewart said.
Stewart believes California's government should support more research into fire-safe building patterns and more effective vegetation management. Perhaps most importantly of all, he said, Californians must turn wildfire history into a learning experience.
"If we don't make significant investments in new ways of managing vegetation and building these housing developments in the (wildland-urban interface)," Stewart said, "we're going to be on this hamster wheel forever."
The news that Americans are getting about California's devasting fires is not being hyped up by the media, said UC Cooperative Extension area fire advisor Lenya Quinn-Davidson on the nationally broadcast NPR program On Point.
Host Eric Westervelt of WBUR in Boston got a Northern California perspective from Quinn-Davidson, who works with communities in Siskiyou, Trinity and Mendocino counties on managing the threat of wildfires and is the Northern California coordinator of the California Fire Science Consortium.
"I definitely don't think the situation is being hyped up," Quinn-Davidson said. "I'm in Ukiah and there's a thick blanket of smoke. Everyone can feel the tension of the Mendocino Complex Fire."
Quinn-Davidson said she grew up in the vicinity and, back then, major fires like those burning today only happened every few years. Lately, such super fire seasons are happening every year. She said it's time for Californians to take a different approach when thinking about fire.
"Fire is the only natural disaster that we fight against," Quinn-Davidson said. "With hurricanes and earthquakes, we adapt and try to identify vulnerabilities and change our behavior. We haven't treated fire like that. We need to learn how to adapt and make changes that make us more resilient to fire."
On Point is NPR's only call-in program. One caller asked whether climate change has reached an irreversible tipping point at which little can be done to reverse the damage that is causing extreme flooding, heat, hurricanes and wildfires.
Quinn-Davidson said she offers hope to the people in communities she serves.
"They're not powerless," she said. "I don't want people to feel that we are beyond some tipping point and they should just throw in the towel. I think we need to feel empowered to make the changes we can make - whether on a personal scale, at at the mid-grade community scale, or if it is taking political action to make larger change ... We still have some place to make a difference. I really believe that."
Michael Mann, professor of atmospheric science and director of the Earth System Science Center at Pennsylvania State University, was also a guest on the On Point program. He said that, as a nation, we may have breached a different tipping point - a tipping point in public consciousness. Recent news reports have informed the public about extreme flooding in Japan, record-breaking heat in Europe and catastrophic wildfires in California.
"This summer has made a difference in the public perception of how profound the threat of climate change already is," Mann said. "And I like to think that when they go to the voting booths in less than 100 days, they're going to be thinking about climate change and the need to act on this problem. I think we will see progress."
When wildfires send smoke into farmland, orchards and vineyards, growers are concerned about the impact of the tainted air on their crops, reported Giuseppe Ricapitio in the Union Democrat.
"It's grapes we worry about the most," said Susie Kocher, UC Cooperative Extension forestry and natural resources advisor. "In the past, there have been bad years when there was a lot of smoke where grapes were on the vine and wineries had to produce the smoky wine because of that effect."
The article said grapes are unlike other agricultural products, in that the skins are permeable. Free volatile phenols created by burning wood become part of the grape itself.
"It isn't something you can wash off," said Ron Harms of Yosemite Cellars winery.
After the 2013 Rim Fire, the winery produced a "Rim Fire Blend," which was successful. However, wine drinkers' palettes differ in terms of their smoke sensitivity. "Some people just can't tolerate (smoke flavor) at all," Harms said.
Other agricultural crops may not be impacted by a blanket of smoke, and some may even benefit. Before Europeans settled in California, Native Americans living in the wilderness would set fires to burn understory brush that built up in the forests.
"It's part of the ecological knowledge of native tribes that smoke is good for trees," Kocher said. "That's not a scientifically proven thing. We don't know."
