The Biden administration said this week it will significantly expand efforts to stave off catastrophic wildfires that have torched areas of the American West by more aggressively thinning forests around 鈥渉ot spots鈥� where nature and neighborhoods collide.

As climate change heats up and dries out the West, administration officials said they have crafted a $50 billion plan to more than double the use of controlled fires and logging to reduce trees and other vegetation in the most at-risk areas. Only some of the work has funding so far.

Projects will begin this year, and the plan will focus on regions where out-of-control blazes have wiped out neighborhoods and sometimes entire communities 鈥� including聽California鈥檚 Sierra Nevada mountains, the east side of the聽Rocky Mountains in Colorado,聽and portions of Arizona, Oregon, and Washington state. Homes keep getting built in fire-prone areas, even as conditions that stoke blazes get worse.

鈥淵ou鈥檙e going to have forest fires. The question is how catastrophic do those fires have to be,鈥� Agriculture Sec. Tom Vilsack told the Associated Press in an interview. 鈥淭he time to act is now if we want to ultimately over time change the trajectory of these fires.鈥�

Specific projects weren鈥檛 immediately released, and it鈥檚 not clear who would pay for the full scope of work envisioned across almost 80,000 square miles 鈥� an area almost as large as Idaho. Much of that area is controlled by states, tribes, or is privately owned.

Reaching that goal would require an estimated $20 billion over 10 years for work on national forests and $30 billion for work on other federal, state, tribal, and private lands, said agriculture聽spokesperson Kate Waters.

Secretary Vilsack acknowledged that the new effort will also require a 鈥減aradigm shift鈥� within the U.S. Forest Service, from an agency聽devoted to stamping out fires, into one that uses what some Native Americans call聽鈥済ood fire鈥澛爋n forests and rangeland to prevent even larger blazes.

Forest Service planning documents indicate the work will focus on 鈥渉otspots鈥� that make up only 10% of the fire-prone areas across the U.S. but account for 80% of risk to communities because of their population densities and locations.

The recently passed federal infrastructure bill put a down payment on the initiative 鈥� about $3 billion over five years that Mr. Vilsack said will get work going quickly.

Wildfire expert John Abatzoglou said lessening fire dangers on the amount of land envisioned under the administration鈥檚 plan is a 鈥渓ofty goal鈥� that represents even more acreage than burned over the past 10 years across the West. But Mr. Abatzoglou, a University of California Merced engineering professor, said the focus on wildfire hazards closest to communities makes sense.

鈥淥ur scorecard for fire should be about lives saved rather than acres that didn鈥檛 burn,鈥� he said.

Mr. Vilsack joined Forest Service Chief Randy Moore to announce the plan during an event in Phoenix where he defended its scope as realistic.

鈥淲e know from a scientific standpoint precisely where this action has to take place in many of these forests in order to protect communities, in order to protect people,鈥� Mr. Vilsack said following the announcement at the Desert Botanical Garden, a popular showcase for cactuses, desert trees, and other dry-weather plants.

Dealing with Western wildfires is becoming increasingly urgent as they get more destructive and intense. There have been rare winter blazes in recent weeks, including infernos in Montana and Colorado, where a wildfire on Dec. 30 tore through a suburban area and destroyed more than 1,000 buildings, leaving one person dead and a second still missing.

And there鈥檚 no signs of a let-up in conditions that keep the risk of wildfires extremely high. A long-term 鈥渕egadrought鈥� is gripping the region and scientists forecast temperatures will keep rising as more climate-changing carbon emissions are pumped into the atmosphere.

The impact stretches far beyond the Western U.S. because massive smoke plumes at the height of wildfire season in the U.S. and Canada spread the health effects across North America 鈥� sending unhealthy pollution last summer to major cities from San Francisco to Philadelphia and Toronto.

For decades the primary approach to containing and extinguishing forest fires was to try to stamp them out. The efforts have been similar to massive, military-like campaigns, including planes, fleets of heavy equipment, and thousands of firefighting personnel and support workers dispatched to the fire zones.

However, fires are a part of the natural cycle for most forests, so putting them out leaves stands of trees that don鈥檛 burn surrounded by dead wood, underbrush, and other highly flammable fuels 鈥� a worst-case scenario when blazes ignite.

Critics say the government鈥檚 plan to use logging to reduce fire damages will hurt both forests and the wildlife and water supplies that depend on them. In South Dakota鈥檚 Black Hills, for example, government biologists have said that too many trees dying from a combination of insects, fire, and logging have made current聽timber harvest levels unsustainable.

鈥淭he U.S. Forest Service simply cannot log its way out of the climate crisis,鈥� said Adam Rissien with the environmental group WildEarth Guardians.

But Mr. Vilsack said a combination of tree thinning and intentionally set fires to clear undergrowth that are called prescribed burns will make the forests healthier in the long run while reducing the threat to public safety.

Forests thinned near Lake Tahoe and its tourism gateway community of South Lake Tahoe were credited with slowing the advance of the massive Caldor Fire last summer that destroyed almost 800 homes and prompted evacuations of tens of thousands of residents and tourists.

A similar phenomenon played out during聽Oregon鈥檚 Bootleg fire聽last July, which burned more than 600 square miles but did less damage in forest that was thinned over the past decade.

鈥淲e know this works,鈥� Mr. Vilsack said. 鈥淚t鈥檚 removing some of the timber, in a very scientific and thoughtful way, so that at the end of the day fires don鈥檛 continue to hop from tree top to tree top, but eventually come to ground where we can put them out.鈥�
