I'm a typical fire idiot, which means I get my information from the local news. The only times I hear about controlled burns is when they go bad and temporarily get out of control. Plus, for the tinderbox areas east and south of me that provide most of my fire risk, I have never seen or heard about a controlled burn. If I add some brain processing to these observations, and throw in California's highly litigious leanings, I would form the loose conclusion that controlled burns are generally avoided here.
As for the influence of the conservationist crowd, I know this: We live adjacent to a valley. In fact, our property is much of that valley, but the valley portion (about 60% of our property) is declared as a nature preserve - can't build on it, can't plant in it, can't change it, can't MAINTAIN it, or you get fined by the county. Ever since we bought the property, I have wanted to thin out the brush in our portion of the preserve, as it is the dry scraggly stuff that grows native everywhere. I have written letters, asked neighbors and HOA for advice, and the answer has always been Sure Try It But You May Get Fined.
In the 2007 Fire, that valley burned right up to a corner of our usable lot, with a nice straight line where the burn stopped in the last 100 feet of wild bushes - according to a fireman who visited us after the fire, that was a well-targeted water drop. Thank you!! That burn sure thinned out the fuel, but within 6 months nature had Found A Way and it was all grown back. Still no success getting permission to cut it back.
Recently, we submitted plans for some work on our property. The fire marshal pointed out the need for 100 feet of defensible space from structures, and I pointed out that we have never been allowed to touch the stuff in the preserve area. He sighed, pointed to his stamp and signature on our plans, and said "This here gives you permission to go in there. Get it done." Yessir! I had been writing to the wrong people, duh. $2,000 later, we have our full 100 feet of defensible space, with the valley thinned out by half of its previous density. It'll probably cost us a grand a year to keep it up, but it's money well spent.
Hopefully I won't have to fight with a different government agency that wants to fine us. Yes, I have plans with The Man's signature, but that may be bringing a toothpick to a gunfight when it comes to a Real Government Administrator which is our County Offices of Land Use or whoever else might come knocking.
