Wildfire protection is a zoning question: 95% of fires reaching western towns came through wildland cover

The ranking is where the argument sits. Thirty-seven land uses, sorted by how often they actually burned between 2000 and 2021, fall into five bands: the safest burned once every 1,400 years or more, the Very Dangerous ones once every 150 years or less ^[3][4]. Wildland vegetation sits in the Dangerous band at one fire per 190 years ^[5], so the safest ground has a return interval roughly 7.4 times longer ^[1]. None of that is a fuel-load measurement. It is a record of what the ground was being used for when fire arrived.

Two of the headline percentages do not nest. The study reports that the fires reaching those 499 communities burned 95% in wildland vegetation and 88% in the Dangerous and Very Dangerous categories combined ^[6]. Wildland vegetation is itself classed as Dangerous ^[5], which means the combined share should be at least 95%, not seven points below it ^[3]. The phys.org summary does not state the denominator behind either figure, and anyone being asked to rezone land on the strength of the number needs that spelled out.

The 2025 Los Angeles fires are offered as independent support, and they are weaker support than the average. The Palisades Fire burned 84.6% in wildland vegetation, the Eaton Fire 81.9% ^[8][9], which puts them 10.4 and 13.1 points below the long-run figure for community-reaching fires ^[2]. The author's reading is that even under strong Santa Ana winds, fires mostly stayed in wildland vegetation and dangerous uses ^[10]. The other reading is that on the windiest days a larger slice of the burn happens somewhere else, and the windiest days are the ones that destroy towns.

Jon Keeley of the U.S. Geological Survey supplies the mechanism in its plainest form: fifty years ago parts of the basin were ringed by citrus orchards, and fires coming out of the mountains burned out in the orchards before reaching homes ^[11]. That is the operative difference between this proposal and thinning. But look at the safe list. Cultivated crops, freeways, lakes, rivers and deserts ^[7]: three of those are pre-existing physical features, which leaves irrigated agriculture and paved corridors as the only safe uses a county can actually install ^[5].

Then the footprint. Communities plus their 5,000 m buffers cover 20.45% of the eleven western states ^[16], about one acre in five ^[4]. Buffers of neighbouring towns merge into continuous belts, as on the Nevada-California line ^[20], and the author's conclusion is that communities have to combine and go to the federal government for major funding ^[18]. The specific ask is that most fuel-reduction treatments under the roughly $7 billion Confronting the Wildfire Crisis program move soon to ground very near communities ^[17][19]. That program exists to reduce fire severity ^[17]. Reducing severity in the backcountry and converting land use next to town are not the same job, and the request is to spend one budget on the other.
