Man, machine and mutton: Inside the plan to prevent the next SoCal fire disaster
Nine months after one of the worst fires the region has seen in recorded history, a helicopter carrying two of the most consequential politicians in the fight against Southern California’s wildfires soared over the Santa Monica Mountains. Rows of jagged peaks slowly revealed steep canyons. The land was blotchy: some parts were covered in thick, green and shrubby native chaparral plants; others were blackened, comprised mostly by fire-stricken earth where chaparral used to thrive; and still others were blanketed by bone-dry golden grasses where the land had years ago been choked out by fire.
Amid this tapestry was a scattering of homes and businesses with only a handful of roads snaking out: Topanga. The dangers, should a fire roar down the canyon, were painfully clear at a thousand feet.
“If there are any issues on the Boulevard…” County Supervisor Lindsey Horvath said into her headset, trailing off.
“The community is trapped,” said Wade Crowfoot, California Secretary for Natural Resources, finishing the thought.
Over the same mountains where the Palisades fire roared, the supervisor and secretary were observing the state’s nearly 675-acre flagship project to stop the Santa Monica Mountains’ next firestorm from devouring homes and killing residents.
Crews from the Los Angeles County Fire Department and the Mountains Recreation and Conservation Authority, a local land management agency, were cutting a miles-long web of fuel breaks in the Northern Santa Monicas between Topanga and Calabasas. In the spring, they hope to perform a prescribed burn along the break. Just northwest, on the other side of Calabasas, Ventura County Fire Department deployed 500 goats and 100 sheep to eat acres of invasive grasses that are prone to conflagration.

It’s just a fraction of the work state leaders and local fire crews hope to someday accomplish, yet the scale and speed of the effort has already made some ecology and fire experts uneasy.
(The goats, however, have enjoyed virtually universal praise.)
While many firefighters and fire officials support the creation of fuel breaks, which offer better access to remote areas during a fire fight, fire ecologists warn that if not done carefully, fuel breaks can make the landscape even more fire-prone by inadvertently replacing chaparral with flammable invasive grasses.
Yet, after the Palisades fire last January, many state leaders and residents in the Santa Monicas feel it’s better to act now — even if the plan is a bit experimental — given the mountains will almost certainly burn again, and likely soon.

In March, Gov. Gavin Newsom signed an executive order streamlining the approval process for these projects. Instead of seeking multiple permits through separate lengthy processes — via the California Environmental Quality Act, Coastal Act, Endangered Species Act, and Native Plant Protection Act (among others) — applicants can now submit projects directly to the California Natural Resources Agency and California Environmental Protection Agency, which ensures compliance with all of the relevant laws.
Consequently, the state has approved well over 100 projects in mere months. Before, it was not uncommon for projects to sit in limbo for years awaiting various approvals.
In April, the state legislature and Newsom approved the early release of funds from a $10 billion climate bond that California voters approved last November for these types of projects. The Santa Monica Mountains Conservancy, which received over $31 million of that funding, awarded just over $3 million to L.A. County and Ventura County fire departments and the MRCA to complete the project.
On Oct. 8, Horvath and Crowfoot watched from a ridgeline northwest of Topanga as crews below maneuvered a remote-controlled machine — named the Green Climber after its color and ability to navigate steep slopes — to chew up shrubs on the hillsides. Others used a claw affixed to the arm of a bright-red excavator to rip out plants.

The goal was to create a new fuel break on a plot of land that is one of the few areas in the Santa Monicas that hasn’t burned in the last seven years, said Drew Smith, assistant fire chief with the L.A. County Fire Department. “Going into the fall, our biggest vulnerabilities are all this right here.”
Left alone, chaparral typically burns every 30 to 130 years, historically due to lightning strikes. But as Westerners began to settle the region, fires became more frequent. For example, Malibu Canyon — which last burned in the Franklin fire, just a month before the Palisades fire — now experiences fire roughly every eight years.
As the fire frequency chokes out the native chaparral ecosystem, fast growing, extremely flammable invasive grasses take over, making it even more likely that a loose cigarette or downed power line will ignite a devastating blaze. Scientists call this death spiral the human-grass-fire cycle. Stopping it is no simple task. And reversing it, some experts fear, may be borderline impossible.
The state’s current approach, laid out by a panel of independent scientists working with California’s wildfire task force, is three-pronged.
First: home hardening, defensible space and evacuation planning to ensure that if a monster fire starts, it causes the smallest amount of death and destruction.
Second: Techniques to prevent fire ignitions in the first place, such as deploying arson watch teams on high-wind days.
Third: Creating a network of fuel breaks.
Fuel breaks are the most hotly debated, in part because fuel breaks alone do little to stop a wind-driven fire throwing embers miles away.
But fire officials who have relied on fuel breaks during disasters argue that such fuel breaks can still play “a significant tactical role,” said Smith, allowing crews to reach the fire — or a new spot fire ignited by an ember — before it blows through a community.

But Dan Cooper, principal conservation biologist with the Resource Conservation District of the Santa Monica Mountains, said there’s little scientific evidence yet that indicates fuel breaks are effective.
And because creating fuel breaks harms ecosystems and, at worst, can make them even more fire prone, fire ecologists warn they need to be deployed strategically. As such, the speed at which the state is approving projects, they say, is concerning.
Alexandra Syphard, senior research scientist at the Conservation Biology Institute and a leading Southern California fire ecologist, noted that the fuel break the Santa Monica Mountains team is creating near Topanga seems to cut right through healthy chaparral. If the fire crews do not routinely maintain the fuel break, it will be flammable golden grasses that grow back, not more ignition-resistant chaparral.
A remote controlled masticator — called the “Green Climber” — mulches flammable vegetation in Topanga to keep flames at a low height.

And the choices land managers make today can have significant consequences down the line: While fire crews and local conservationists are experimenting with how to restore chaparral to grass-filled areas, in the studies Syphard has looked at, once chaparral is gone, it seldom comes back.
For Cooper, the trade-offs of wildfire risk reduction get at a fundamental tension of living in the Santa Monicas. People move to places like Topanga, in part, because they love the chaparral-dotted vistas, the backyard oak woodlands and the privacy of life in the canyon. Yet, it’s that same environment that imperils them.
“What are you going to do about it? Pave the Santa Monicas? A lot of the old fire guys want to make everything grass in the Santa Monicas because grass fires are just easier to put out,” he said. “We need to learn how to live with fire — in a lot more sober way.”

L.A. County stores must immediately stop selling kratom and 7-OH, health department warns
Los Angeles County officials are set to pull kratom and its synthetic extract, sometimes called 7-OH, from shelves immediately.
Inspectors will be sent to retailers next week to begin red-tagging illegal products containing the compounds, the L.A. County Department of Public Health said in a news release Friday morning. Shops that don’t comply could be hit with fines or other penalties.
Kratom is an herbal extract from the leaves of Mitragyna speciosa, a tree native to Southeast Asia. It is sold in shops and online in a variety of forms, including powders, pills and liquid extracts. Brands selling kratom often make claims that it can address pain, anxiety and mood disorders.
Matthew Lowe, executive director of the Global Kratom Coalition, said natural kratom has been used in the U.S. for more than 50 years and according to a 2020 Johns Hopkins Survey, people have been using it to alleviate anxiety and treat chronic pain.
In the last few years, a more potent, synthetic version of kratom refined into its psychoactive compound 7-Hydroxymitragynine, or 7-OH, hit shelves across the U.S.
7-OH products are often marketed as “plant alkaloids,” drawing criticism from some, including Lowe, who argue the labeling is misleading, confusing consumers into thinking it’s the same as natural kratom.
When mixed with alcohol, medications or illicit drugs, the county health department warns, 7-OH products can “cause severe respiratory depression and death. Importantly, these products are unregulated and may contain unknown concentrations of 7-OH, increasing the risk of unintentional overdose.”
There have been six reported kratom-related deaths in Los Angeles County in just the past few months.
“Given that this is new and emerging substance, this is also since the medical examiner started tracking 7-OH data,” the Los Angeles County Department of Public Health told The Times via email. Since the county began tracking 7-OH in deaths only in April of this year, it is unclear how many other overdoses could have occurred previously.
After publication of this article, the county medical examiner released the death reports to The Times. Each of the deceased had kratom and 7-OH in their bodies, according to the reports, but it was not immediately clear what role they played in the deaths, as compared with other substances — including alcohol, prescription sedatives and muscle relaxants, and illicit drugs like cocaine — that were also found in the six bodies. The Times first requested the coroner’s report for the kratom-related deaths on Oct. 24.
“Kratom and 7-OH products are sold as natural remedies, but they are illegal and unsafe,” Dr. Muntu Davis, the county health officer said in the release. “They are sold in gas stations, smoke shops, online, and other retailers. People should avoid using these products, and store owners/operators must remove them immediately to prevent harm.”
Right now, consumers have no clarity on kratom, 7-OH or any other metabolites, said Yaël Ossowski, deputy director of Consumer Choice Center, a nonprofit consumer advocacy group.
“At any gas station or smoke shop, there’s the powder, the liquid extracts, and pills all offered at different doses, with different brands,” Ossowski said. “This obviously leads to consumer confusion and uninformed choices, incorrect dosing and likely bad experiences that smart regulation would avoid.”
The kratom and 7-OH market has grown largely because people want targeted pain relief and remedies for their ailments, “but don’t necessarily want to have the full effects of more powerful opioids that have a fuller effect on the body,” he said.
“Kratom has been successfully used for generations in other countries as an opioid alternative,” Ossowski said. But highly concentrated 7-OH products are a different beast altogether.
According to the U.S. Food and Drug Administration, kratom and 7-OH are not lawfully marketed in the U.S. as a drug product, a dietary supplement or an approved food additive.
California adopts federal law concerning food and dietary supplements, the California Department of Public Health told The Times via email.
“Until kratom and its pharmacologically active key ingredients mitragynine and 7-OH are approved for use, they will remain classified as adulterants in drugs, dietary supplements and foods,” a department spokesperson said.
The spokesperson added that the department has been conducting investigative work associated with kratom for the last two years and “continues to take appropriate action to protect the public against adulterated products containing kratom or 7-OH.”
“CDPH embargoes or destroys foods and dietary supplements within the state that are adulterated with kratom or 7-OH once they are identified during investigations; however, we do not comment on the specifics of ongoing investigations,” the spokesperson said.
7-OH producers have publicly defended their products in the face of lawsuits and FDA crackdowns, arguing it is a safer alternative to illicit opioids like fentanyl and has saved lives, not taken them.
Vince Sanders, founder and CEO of CBD American Shaman who helped develop an early 7-OH product, has said the attack on 7-OH is being led by companies selling natural kratom, who have had their market share overtaken by what he says is “a vastly superior product.”
The Kansas City businessman said a ban anywhere in the country would hurt people who have used 7-OH to treat substance abuse disorders or chronic pain and now rely on the product as an alternative to costly prescription medication.
“People that have changed their life using it are extremely concerned,” Sanders said. “They’re scared to death. I mean, there are people that … plan to pull money out of their 401K, or load up their credit cards, or whatever they’ve got to do to buy years and years of supply.”
He acknowledged that both kratom and 7-OH are frequently taken in higher doses than he recommends, but argued manufacturers and retailers should not be held accountable for those decisions. He compared it to alcohol: “You buy a 750-milliliter bottle, and if you go home and drink that entire bottle, and you do that every single night, is that your fault, or is that Jim Beams’ fault?”
Communities across the state have taken it upon themselves to act in the absence of state and federal regulation. Orange County and the cities of Newport Beach, San Diego and Oceanside have all prohibited the sale, distribution or possession of kratom. Riverside County is looking to deter the sale and marketing of kratom and 7-OH products to people under the age of 21.
Los Angeles County does not have its own regulatory ordinance for the products.
“I think that the local action is signaling intent. It’s saying to the state and [federal authorities], you need to do something about this,” Lowe said in regard to synthetic 7-OH.
But outright prohibition bans that include natural kratom could bring another host of issues including whether local enforcement of the ban will even happen, and the possibility that a black market for the products may arise, he said.
“You leave people without any options, so they either find alternative options or they just drive across city lines or county lines and and go get it themselves,” Lowe said. Indeed, kratom and 7-OH are widely available on online marketplaces.

L.A. air officials approve port pollution pact as skeptics warn of ‘no clear accountability’
Southern California air officials voted overwhelmingly Friday to give themselves the power to levy fines on the ports of Los Angeles and Long Beach if they don’t fulfill their promises to transition to cleaner equipment.
The ports remain the largest source of smog-forming pollution in Southern California — releasing more emissions than the region’s 6 million cars each day.
The South Coast Air Quality Management District’s governing board voted 9-1 in favor of an agreement that commits the ports to installing zero-emission equipment, such as electric truck chargers or hydrogen fuel pumps, to curb air pollution from the heaviest polluters. The plans will be submitted in three phases: heavy-duty trucks and most cargo-moving equipment by 2028; smaller locomotives and harbor crafts by 2029; and cargo ships and other large vessels by 2030.
If the ports don’t meet their deadlines, they would be fined $50,000 to $200,000, which would go into a clean-air fund to aid communities affected by port pollution. The AQMD, for its part, forgoes imposing new rules on the ports for five years.
Many environmental advocates voiced disappointment, saying the agreement doesn’t contain specific pollution reduction requirements.
“I urge you not to sign away the opportunity to do more to help address the region’s air pollution crisis in exchange for a pinky promise,” said Kathy Ramirez, one of dozens of speakers at Friday’s board meeting. “This is about our lives. I would encourage you to think about why you joined the AQMD board. If not for clean air, then for what?”
Port officials and shipping industry officials lauded the decision as a pragmatic way to transition to a zero-emissions economy.
“The give and take of ideas and compromises in this process — it mirrors exactly what a real-world transition to zero emissions looks like,” said William Bartelson, an executive at the Pacific Maritime Assn. “It’s practical, it’s inclusive and it’s grounded in shared goals.”
The vote answers a long-standing question over how the AQMD intends to reduce pollution from the sprawling trade complex, a focus of environmental justice efforts for decades.
The twin ports of Los Angeles and Long Beach, known as the San Pedro Port Complex, is the largest container port in the Western Hemisphere, handling 40% of all container cargo entering the United States. Despite years of efforts at reducing pollution, the vast majority of heavy machinery, big rigs, trains and ships that serve the region’s bustling goods movement still are powered by diesel engines that emit toxic particles and nitrogen oxides, a precursor to smog.
For nearly a decade the AQMD has vacillated between strict regulation and a pact with the ports with more flexibility. Several negotiations over a memorandum of understanding failed between 2017 and 2022. The board was prepared to require the ports to offset smog-forming pollution from trucks, trains and ships through clean air projects, like solar panels or electric vehicle chargers. Instead, the ports presented the AQMD with a proposed cooperative agreement, prompting the agency to pause its rulemaking.
The AQMD doubled the penalties in that proposal and agreed not to make new rules for five years, not the 10 the industry wanted.
Perhaps the most important details of the agreement — the types of energy or fuel used; the appropriate number of chargers or fueling stations — won’t be published for years. The lack of specifics prompted skepticism from many environmental advocates.
“It’s just a stall tactic to make a plan for a plan in the hope that emission reductions will come sometime in the future,” said Fernando Gaytan, a senior attorney with environmental nonprofit Earthjustice.
The contract also includes a clause that the AQMD or ports could terminate the agreement “for any reason” with a 45-day written notice. Wayne Nastri, the AQMD’s executive officer, said this gives the agency the option to switch back to requiring zero-emission infrastructure at the ports.
“If we report back to you and you’re not seeing the progress being made, you can be confident knowing that you can pivot and release that [rulemaking] package,” Nastri said to the board.
At the end of public comment, opponents of the agreement broke into loud chants. The AQMD cleared the gallery as the board discussed the proposal.
Board member Veronica Padilla-Campos, the lone “no” vote, said the agreement lacked the necessary emission reductions and offered “no clear accountability” to local communities.
Fellow board member Nithya Raman acknowledged many criticisms of the agreement but ultimately voted for it.
“I really have come to believe that the choice before us is this cooperative agreement or no action at all on this issue — continuing a decade of inaction,” Raman said.
“I will be voting to support it today, because I do think that it is our only pathway to take any steps forward toward cleaner air at the single largest source of air pollution in the region.”
The plan still must be approved by commissioners at the Port of Los Angeles and the Port of Long Beach Harbor Commission at meetings this year.
