Protecting Habitat, Preventing Destructive Fire: Creating More Effective Wildland Management Policies

Key Takeaways

• Prescribed Burns are Largely Ineffective in Chaparral: Conducting prescribed fires in the intact chaparral and coastal shrubland ecosystems of the Santa Monica Mountains is expensive, dangerous, and ecologically detrimental.
• A Holistic Mitigation Framework is Required: Wildfire risk management must move away from isolated approaches and overlap three domains: the built environment, the community, and the landscape.
• True Purpose of Fuel Breaks: Fuel breaks and dozer lines do not stop severe wind-driven fires on their own; their primary success stems from providing strategic access to firefighters.
• Data Sharing and Leadership Gaps: Agencies currently operate in silos. There is a critical need for centralized, public-facing data sharing, more interagency cooperation, and a unified consensus narrative to combat public misinformation.
• Dwindling Funding: Financial support for fire prevention, community education, and forestry management is shrinking across all levels, triggering concerns over public backlash and community vulnerability.

On June 12, 2026, UCLA’s Sustainable LA Grand Challenge—in partnership with the offices of Los Angeles County Supervisor Lindsey Horvath, State Senator Ben Allen, and State Assemblymember Jacqui Irwin, and with the support of volunteers Tessa Charnofsky, Rachel Burnap, and Julie Clark—convened 30 ecologists, community leaders, and representatives from state and local fire and land management agencies, conservation organizations,, and the elected offices for a workshop titled Protecting Habitat, Preventing Destructive Fire: Creating More Effective Wildland Management Policies

The goal: identify areas of consensus regarding wildfire mitigation, firefighting practices, and ecosystem conservation, while also clarifying areas of disagreement and uncertainty.

The January 2025 firestorms in Los Angeles threw into stark relief a growing challenge: fires in the wildland-urban interface are becoming more extreme, threatening more homes and communities. With this come questions about the best ways to mitigate these threats.

Prescribed burns, excessive thinning, and fuel breaks remain common practice despite the science showing that in the chaparral and coastal shrublands of Southern California, they are not effective, and likely actually increase fire risk.

The conversation was organized around three areas:

• Pre-Fire Interventions and Hazard Reduction
• Active Suppression and Containment 
• Post-Fire Rehab and Recovery

Framing the overall conversation was the reality that fire is inevitable, but intervention and planning can help mitigate the harm fire causes to people’s lives, property, and livelihoods. Any strategies will have to be forward-looking and planned with the reality of a changing climate in mind.

Pre-Fire, Hazard Reduction, and Ecosystem Management

The Chaparral Ecosystem

Chaparral and coastal shrublands represent the dominant native vegetation in the Santa Monica Mountains. 

Meeting attendees strongly emphasized that prescribed fires are not a viable tool for intact habitat—in contrast to areas overrun with invasive species or otherwise degraded— because they are difficult to safely implement, economically inefficient, and ecologically harmful.

• Chaparral is naturally adapted to infrequent fire cycles and critical for slope stability in mountainous terrain.
• If the fire return interval drops below 20 years, native shrubs and specific species (such as Ceanothus) cannot recover or re-germinate.
• Frequent burning results in a Vegetation-Type Conversion (VTC), where the native habitat is replaced by highly flammable, flashy invasive species that can burn as soon as five years after a previous fire.

Fuel Replacement vs. Fuel Removal

Management practices should continue to shift from blanket vegetation removal to targeted hazardous fuel removal, specifically focusing on invasive species.

• Mowing Trade-offs: Current practices like late-season mowing are necessary short-term fixes, but they actively spread the seeds of invasive weeds.
• Native Restorations: Restoring native plants (e.g., planting over 15,000 native oak trees as green breaks within the Wildland-Urban Interface) acts as a fire-resistant buffer and prevents VTC.
• Seed Deficits: Upscaling restoration across the mountains' seven distinct zones is severely limited by the availability of locally-sourced native seeds. To counteract this, seed amplification programs are operating out of local sites like Paramount Ranch and Rancho Sierra Vista.

Active Suppression and Containment

The Strategic Value of Fuel Breaks

A significant disconnect exists between public perception and scientific reality regarding fuel breaks.

• Fuel breaks and dozer lines do not change the trajectory of or stop wind-driven fires, which can carry embers up to 2 to 5 miles away.
• They are only effective when they actively facilitate firefighter access to the fire line.
• When constructed poorly or left unmaintained, wide fuel breaks become an ecological disaster by establishing new habitats for highly flammable invasive species.

Tactical Firefighting Interventions

Firefighters evaluate fires based on distinct behaviors at the head, flank, and heel.

• Dozer Lines: Temporary emergency contingency lines are carved out via bulldozers ahead of a fire's path, strategically utilizing topographically wind-sheltered areas.
• Surgical Response: Because fine fuel moisture content is the primary driver of rapid fire spread, suppression efforts must be highly targeted. Containment lines should be scaled back in inactive zones to preserve resources.
• Interagency Coordination: During incidents, fire agencies should work closely with local land management agencies and other relevant experts in siting new contingency lines to avoid damage to particularly sensitive habitat while still achieving firefighting objectives.

While the focus of the discussion was on fire mitigation in wildlands, attendees brought up related issues, specifically home hardening and neighborhood planning, enforcing defensible space rules, and insurance coverage.

Home Hardening and Retrofitting

Wildfire risks operate at multiple levels: individual buildings, lots, neighborhoods, and entire communities. While designing new developments to modern fire standards is relatively straightforward, protecting existing development demands massive structural retrofitting.

• Urban fire spread is frequently driven by structure-to-structure ignition rather than wildland vegetation.
• Mitigation strategies must prioritize home hardening, maintenance, and structure spacing.

Defensible Space Enforcement

The Los Angeles County Fire Department utilizes a three-pronged approach integrating home hardening, defensible space fuel reduction, and public education.

• On any given day, approximately 40% of the area's 1,000 firefighters are deployed to conduct defensible space inspections.
• Because firefighters face extreme time constraints trying to cover entire communities, these visits function strictly as legal compliance inspections rather than detailed property evaluations.
• Though standardized training programs are developed through the Board of Forestry to improve consistency, inspection quality and expertise can still vary across personnel.

Insurance and Public Communication Gaps

Legislative offices face immense pressure from constituents regarding the stabilizing wildfire insurance market.

The Insurance Crisis: Homeowners actively performing mitigation feel they are doing their part, yet insurance companies continue to demand extensive modifications or drop coverage entirely.

To bridge this, community engagement programs (like the Home Ignition Program in Topanga) are framing home hardening as a dual mechanism for survival and financial incentive, helping homes remain insurable. Furthermore, public education must debunk prevalent misinformation; for example, clearing vegetation beyond 100 feet is not evidence-based, yet extreme claims demanding 700+ feet of clearance still circulate and in the City of Los Angeles, the LAFD Fire Code requires that brush clearance extend to 200 feet.

Post-Fire Rehabilitation, Data Sharing, and Funding

Intervention Methods

After the fires, immediate post-fire rehabilitation is required to prevent downstream environmental disasters, such as severe debris flows, mudslides on steep terrain, and invasive takeovers of burn areas. 

• Using water bars (or water guards) can prevent sediment from contaminating residential, municipal, and environmental streams.
• Deploying hydro-seed machines to disperse native seeds downhill with incoming rains, preventing annual grasses from overwhelming hazardous terrain.
• Utilizing specialized Watershed Emergency Response Teams (WERT) to quickly analyze vulnerable landscapes.

Interagency Coordination and Data Sharing

Because different entities own overlapping parcels across the mountains, agencies frequently operate in silos. This also causes confusion for residents and other stakeholders around who is responsible for intervention and maintenance.

Participants discussed the need for both more formalized interagency coordination and cooperation. There was a suggested recommendation for expanding existing frameworks, such as the Santa Monica Fire Safe Alliance, into a centralized Joint Powers Authority (JPA) format. 

Additionally, participants called for the creation of a shared, public-facing regional map and data dashboard that would allow legislative offices and constituents to verify mitigation progress, track native planting successes, and improve interagency coordination. 

Currently, establishing baseline metrics to accurately measure fire prevention success remains a major operational hurdle.

There Are No Silver Bullets

No single strategy works everywhere. While vegetation clearing may cause more problems by making room for more flammable invasives, there are places where strategic thinning can reduce fire risk, especially along the wildland-urban interface.

Still, how to go about that matters. One popular option—using goats to graze—raises other questions, as goats are indiscriminate in their dietary choices. And, while prescribed burning degrades chaparral areas, in areas such as those consisting entirely of invasive species, it can be used to good effect.
