It is clearly working here in Colorado.
Maybe as much in the Forest as it is reflected in the surrounding area of adjacent dwellings.
In order to get a building permit, even for a deck, your property needs to comply with definable space and fire mitigation standards.
It is part of my long term goal, as I know I will not be able to keep my currant day job for maybe another 10 years, and hope to get more involved with the thinning that is so needed.
To give you an idea, from here, I can see the beginning of the Pike National Forest, it is 1,000,000 acres of tender-box, standard bore samples of standing timber measure at just above 10% moisture,,,,,when fires start, if the wind picks up to even 15 MPH, the fires get into the tops and travel at exactly the speed of the wind, and can not be put out!
With out the Act, tree-huggers just had too much pull, some of the off shoots from the act is the un-lawfulness of obstructing logging and thinning operations.
The BLM and Forest Service now admit that 100 years of fire suppression did not work, but now there are just too many home and people in the way, and way too many acres involved when fires do ignite.
Just the term Healthy suggest it all, I had the good fortune to have meet one of the planers from the National level, and he gave me the description that Healthy is the same as Natural in many cases, and just removing the excess fuel wood will work in many areas.
Picture a hike in the mountains through an area that has grass growing between the trees, the huge old trees being the old pumpkin-colored bark pines and Douglas-fir, a few stands of saplings and the sun reaching most of the ground,,(as opposed to 150 year old stands of dog-haired Lodge-pole Pine),,,, for most of Colorado, that is the only way there is enough water to make everything grow the way nature intended.
