With California's wildfires expected to worsen in coming years, the state is looking at different ways to prevent fires.
There are the usual methods like fire retardant and controlled burning — and then there are goats.
Goats can get up steep hills and thin down plant coverage, making it harder for fires to spread.
They're called nature's lawnmowers for a reason.
Goats are hungry, agile, and far from picky. Across California, herds of goats are being used to prevent wildfires — alongside more traditional forms of fire prevention.
Goats are carbon-friendly, prefer weeds to native plants, and can get up steep hills that humans and machines can't get to.
Here's how goats are working to prevent California's fires.
Every year, wildfires rage across California. Less than 25 years ago, in 1999, 273,000 acres burned in California. This was considered a bad season back then, but as the population in the state has grown and moved deeper into wildfire territories, it's only gotten worse.Firefighters near a home on fire in Santa Rosa in 2020.
In 2021, more than 2 million acres of wilderness in California burned. Last year was declared "unexpectedly quiet" when 362,000 acres burned — this is still almost 100,000 acres more than in 1999.Flames rush uphill behind cars toward Meyers, California, in 2021.

Overall, California is having larger and more intense fires and experts warn it's only going to get worse.
To combat the fires, there are the traditional methods like spraying fire retardant. In 2020 and 2021, the Forest Service used about 50 million gallons of the substance.A California resident watches an air tanker drop retardant as the Electra Fire burns towards her home in the Pine Acres community of Amador County on July 5, 2022.

It's not just a reactive measure either, but one that can be sprayed before the fire season and can last for months if there's no heavy rain.
There's also a need for residents and the government to work out which homes and communities have become too risky to remain where they are.A goat herder shepherds a herd of goats from Mascauser Vineyards and Ranch in Napa Valley, California, on September 27, 2020.

Goats have become a mainstay for fire prevention. It takes about 100 goats to graze over an acre in a day. They thin down plant coverage, making it harder for fires to spread.A goat stands on its hind legs to reach a branch to eat in Anaheim in 2022.
They've also become increasingly useful as invasive weeds flourish. The National Park Service calls these weeds "LA's Evil Plants" because they grow and dry out quickly, increasing the risk of fires due to how easily they burn.Goats graze on a hillside in Irvine in 2018.

"If you throw a bunch of matches into a forest, some small percentage of them might actually start a fire, but if you throw a bunch of matches into a big hay pile, there's a good chance that many of those will catch fire," Bethany Bradley, an environmental conservation professor at University of Massachusetts Amherst, told NPR.
Goats have a secret, fire-fighting weapon — their hunger. Their metabolism is unusually high, according to City Grazing executive director Genevieve Church.A goat is seen with his mouth agape on a branch while grazing in South Pasadena in 2019.
They can also climb up steep hills that are otherwise difficult for humans or machines to reach.A herd of goats graze on drought-stressed elevated land in 2022 in Anaheim, California.
They're happy to eat invasive plants like ivy and blackberries. And in general, they're not picky eaters.Goats graze on dried grass on Bay Area Rapid Transit property on July 27, 2022 in Walnut Creek, California.
Brea McGrew, who had a herd of goats working across Oakland, Berkeley, Monterey, and Malibu since as early as 1991, told the Smithsonian Magazine: "They like their food right at eye level. At home, the goats ignore the wonderful green grass and look longingly at the scruffy taller stuff beyond the fence."A goat grazes on on Bay Area Rapid Transit property in Walnut Creek, California in 2022.
And if something looks particularly tasty, they're willing to work for it. McGrew said they worked together, with one goat getting onto its hind legs to get a branch down so that others could have a good chew.Goats eating vegetation in Glendale, California in 2021.

Goats are also carbon-friendly. The only thing they leave behind are their droppings, which serves as a good fertilizer.A goat named Princess, who is part of City Grazing’s working herd.
What's even better is that after a goat eats an invasive plant, the seed goes through its digestive tract. When it is excreted, the seed can't grow again.A herd of goats in Anaheim in 2022.
But goats aren't exactly a new innovation to fire prevention efforts. Laguna Beach was using a herd of 400 to keep the bush down back in 1993.A herd of goats grazing on a hillside in Laguna Beach in 2000.

But according to the San Francisco Examiner, the use of goats represents a shift in California's long-term fire management strategy, which used to leave large sections of grassland and forest untouched.A goat herder corrals a herd of goats being evacuated during a fire in Napa County in 2020.

"In terms of managing fuel loads, mowing is probably just as effective as grazing except on steep or rocky terrain," Robert Freese, program manager at the Irvine Ranch Conservatory, told National Geographic.
They can also be expensive compared to hiring weed trimmers — except when the grazing is done on a massive scale.Herds of goats roam fields in Laguna Beach where they eat brush as part of the city's fire prevention measures.

But goat herders are facing another issue — costs. Last year, a new law changed overtime rates for goat herders. It ensures that herders are paid 168 hours per week, because they are on-call 24 hours a day, seven days a week. This meant wages for sheepherders basically doubled.Grazing goats alongside Alissa Cope from the goat herding company Sage Environmental Group in 2021.
As Freese told National Geographic, the best way to prevent fires involves a number of methods, including controlled burning, herbicides, and manually clearing brush.Goats graze on a hillside in 2019 in South Pasadena.
Goats are just one of the methods, although undoubtedly they're the most memorable method. As Steward Andree Soares, who owns grazing company Star Creek Land, told the San Francisco Examiner: "Once people see it, they can't unsee it."Goats protecting Laguna Beach homes in 2000.
