Why Did California 'Stop' Clearing the Brush? The Real Story Behind a Misleading Question

After every major wildfire in Southern California, the same question floods social media: “Why did California stop clearing the brush?” The framing usually pairs with a photo of a hillside that burned and an implication that somebody, somewhere, made a policy choice to let the fuel build up.

The honest answer is more interesting — and more useful for Wood Ranch homeowners — than the question suggests. California didn’t stop clearing brush. The state, federal agencies, and local fire districts clear millions of acres of vegetation every year through a combination of mechanical fuel reduction, prescribed burns, and homeowner-led defensible space work. What actually happened over the past 30 years is that the mix of those approaches shifted, lawsuits and air-quality regulations slowed the most effective large-scale tool, and the responsibility for the work has increasingly moved from agencies to individual property owners.

For homeowners in Wood Ranch, Bell Canyon, and Bridle Path, the practical takeaway is the part the social media posts miss: whatever the agencies are doing or not doing at the landscape scale, your defensible space is the variable you control. And that’s where the system is putting the most pressure right now.

What “clearing the brush” actually means

The phrase covers three different categories of work, and conflating them is most of why the question feels so confusing.

Prescribed burns are intentional, planned fires set by trained crews under permitted conditions to reduce fuel loads across large landscapes. CAL FIRE, the U.S. Forest Service, and tribal cultural fire practitioners do this work. It’s the most efficient fuel-reduction tool we have — a single well-executed burn can treat thousands of acres at a fraction of the cost of mechanical clearing.

Mechanical fuel reduction is the equipment-and-crew version: bulldozers cutting fire breaks, masticators chewing through brush fields, tree thinning crews working forested areas. It’s slower, more expensive, and harder to scale, but it doesn’t generate smoke or require the same weather and permit conditions.

Defensible space work is what individual property owners do (or hire contractors to do) within 100 feet of their structures. Brush clearance, weed abatement, Zone 0 ember-resistant work, tree spacing. This is the smallest category by acreage but the highest-leverage category for keeping homes standing during a wildfire.

The “why did they stop” narrative is mostly about the first category — prescribed burns. The other two have either stayed steady or expanded.

The prescribed burn story is the real one

California genuinely does less prescribed burning than fire scientists say it should. The numbers tell the story: state agencies, federal land managers, and partners burn somewhere around 125,000 acres a year statewide, according to the California Air Resources Board. The 2022 California Wildfire and Forest Resilience Task Force Strategic Plan set a target of 400,000 acres annually by 2025. We’re still well short of that goal.

The reasons aren’t a single villainous policy. They’re a stack of overlapping constraints:

Liability and insurance. Prescribed burn practitioners historically struggled to get adequate liability coverage. A burn that escapes containment — even a small one — can generate million-dollar claims. The state created the Prescribed Fire Liability Fund Pilot Program (PRC sections 4500 and 4503) to address this, but the legal exposure still chills participation by private practitioners and even some agency partners.

Air quality regulation. California Air Resources Board and local Air Quality Management Districts have to approve every burn through smoke management plans. Burns can only happen on approved “burn days” with favorable weather and dispersion conditions. In dense Southern California air basins, those windows are narrow.

Environmental review. Federal and state environmental laws (NEPA and CEQA) require review for many burn projects. A 2007 lawsuit by the Sierra Club against the U.S. Forest Service eliminated categorical exclusions for prescribed burns, meaning many projects now require full environmental impact statements. These reviews can take years.

Community opposition. Neighbors near proposed burn sites often oppose them, citing smoke concerns and fear of escaped fire. A 2019 proposed 400-acre burn in Malibu was shelved after public opposition. Los Angeles County didn’t conduct a prescribed burn for more than a decade before the early 2020s.

The net effect: prescribed burning gets done in fits and starts, often at smaller scale than the fuel conditions warrant, and the gap between “burns we should be doing” and “burns we are doing” has grown.

What changed in the past five years

Beginning around 2020, the policy direction reversed. The combination of Camp Fire (2018), the 2020-2021 megafires, and the political consequences of those losses pushed California toward expanding prescribed fire rather than constraining it further.

Governor Newsom signed Executive Order N-05-19 specifically authorizing prescribed fire as a means to reduce wildfire risk. The 2022 Strategic Plan set the 400,000-acre target. The state invested $1.5 billion in wildfire resilience in 2021 alone, with significant support for prescribed and cultural burning. Tribal cultural burning, suppressed for over a century, is being formally recognized and coordinated with state and federal agencies again.

At the federal level, the Forest Service has expanded its prescribed fire program — over 72,000 acres burned on California national forests in 2024 alone.

The trajectory is clear: more prescribed burning, not less. But the structural constraints — liability, air quality, lawsuits, community resistance — are still real. Progress is real but slow.

Where homeowners come in

While the agency-led fuel reduction conversation is happening at the landscape scale, the more immediate and personal shift has happened at the property level. California’s defensible space law has tightened steadily since 2005, and the trend accelerated after 2018.

The legal stack now includes:

• California Public Resources Code 4291 — the original 100-foot defensible space requirement around any structure in a Fire Hazard Severity Zone.
• Government Code 51182 — the local enforcement layer, allowing fire districts to set requirements stricter than state minimums.
• Assembly Bill 3074 (2020) — added Zone 0, the 5-foot ember-resistant zone around structures. The state Board of Forestry finalized Zone 0 regulations, and local districts have been activating them. VCFD activated Zone 0 on March 1, 2025 for new construction and additions, with strong recommendations for existing buildings.
• Local ordinances — in Ventura County, VCFD Ordinance 32 and Standard 515 add specific requirements on top of state law, including slope-adjusted distances, tree canopy spacing rules, and prohibitions on combustible mulch and synthetic turf in Zone 0.

The pattern across all of these: stricter rules, more documentation, shorter cure periods when properties fail inspection, and higher penalties for non-compliance. The state’s response to “we can’t clear enough at the landscape scale” has been “then we need property owners to clear more at the parcel scale.”

What this means for Wood Ranch homeowners

A few practical takeaways:

Your defensible space matters more, not less. As agency-led landscape burning struggles to scale, the property-level defensible space requirements get more important — and more strictly enforced. VCFD inspectors are citing more violations than they did a decade ago, the cure periods are shorter, and the cost of failure (county-contracted abatement at 2-3x private contractor rates plus admin fees) is real.

The rules will keep tightening. AB 3074’s Zone 0 is the most recent expansion, but it won’t be the last. Insurance companies are already enforcing stricter defensible space standards as a condition of coverage. Homeowners who bring their properties into compliance now are getting ahead of an enforcement curve that’s already moving.

Don’t wait for the inspector. The annual VCFD inspection cycle starts with notices mailed April 20 each year, with field inspections running May through July. By the time you get a Notice to Abate, you have 30 days to resolve it — and during peak season, every contractor in Ventura County is booked solid. The cleanest path is to get the work done in January through March, before notices go out and before the calendar fills.

The hillside work is different. Wood Ranch’s hillside lots trigger the slope-adjusted Zone 1 (50 feet instead of 30), require specialized equipment and crew training, and need different timing because of ground saturation and crew access. A flat-lot landscaper doing hillside brush work is how compliance violations and safety problems happen.

The framing that helps

“Why did California stop clearing the brush?” is the wrong question because California didn’t stop. The right question is: “Where is the work happening, who’s doing it, and what’s my part?”

The answer for a Wood Ranch homeowner is straightforward. Agencies are doing what they can at the landscape scale, slowly and with real constraints. Your defensible space is the part you control. The standards are getting stricter and the consequences for missing them are getting more expensive. Doing the work right, on a sensible schedule, with a contractor who knows VCFD’s actual requirements is the highest-leverage thing you can do to protect the property.
