Most importantly California policies govern the management - or mismanagement - of the wildfire "prevention".
Here in Michigan we fend off some 100 legal challenges/year from the EPA fruitloop Sierra Club pukes over our prescribed burns. 600 wildfires here last year and only 3000 acres burned. Why? Because we don't kow-tow to the envirowhackos and we still manage our forests by reducing fuel. And, btw, we have more forest than any other state in this country. So we know wildfires. We have 20 million acres of forest, and how often do you hear about our state having wildfires out of control? It's very very dry here except in August.
In California the Sierra club pukes run the show and they don't even try to manage the fuel, therefore when they have wildfires, they get worse and worse over time.
Funny thing about that link you posted. If you scroll down to the map, you’ll see large white areas where Calfire doesn’t do fuel reduction. Those are the areas marked “federal jurisdiction.” That includes the Angeles National Forest, where this fire occurred.
First off, Michigan has about three times the average rainfall the Los Angeles area sees. It rains (or snows) there pretty much any month of the year, while Los Angeles sees basically none outside the January to March period. Nor is there the zero humidity, 90 degree, 50 mph Santa Ana winds howling down through the canyons from the high desert. Second, the vegetation of Michigan is not the highly combustible chaparral sage and manzanita that makes up the area. Finally, the terrain is wildly different. There are no canyons or steep slopes in Michigan. In fact, in the Angeles National Forest you can quite easily find more elevation difference between two points a quarter mile apart than exists between the low point (571 feet) and high point (1979 feet) in the entire state of Michigan. So don't be thinking it's an apples to apples comparison.
