I live in California and spend most of my outdoor adventures backpacking and camping trips in the Sierra's, Desolation Wilderness, Tahoe, etc. I go all seasons and actually enjoy winter trips more than anything to avoid any of the crowds. I only carry an axe if it's during the winter and spring months, where there is snow or we are expecting cold weather. That way if I have a hard time finding dry smaller pieces of wood I can process portions of downed trees and deadwood. I never take all of the dead wood from any particular location as to leave the least amount of impact for natural decomposition. Unfortunately, this mentality can lead to issues in the backcountry, especially during winter trips in the Sierra's. Two of my buddies and I did a winter trip last year and snowshoed into one of them many lakes in the Tahoe National forest. We came across two guys who didn't bring any tools to process firewood and temps were dropping into the teens. We saw them walking around the lake trying to find burnable wood. Fortunately for them we brought our axes and saws, so we had plenty of wood processed for a nice campfire that lasted 9 hours.
We also generally have very strict fire restrictions during the summer months, so campfires in the backcountry are generally restricted. That doesn't mean there is a shortage of idiots having raging fires and leaving burning dead wood in pine needles. However, once you get several miles into the backcountry there tends to be much more fallen deadwood, pine needles, and dry debri laying around. I believe that in some cases we are helping by burning some of the debri to reduce the intensity of potential forest fires. California has had some nasty forest fires and even fires that burn through cities and neighborhoods recently. I believe that our firefighting and the technology we use to fight fires has disturbed the natural eco systems because you can find areas with 1-3 feet of dried deadfall, pine needles, etc. It's disaster waiting to happen because the controlled burns and many of the fire prevention by gathering and burning or taking this debri out is cumbersome deeper into the forests. Desolation Wilderness doesn't allow campfires and you can see the evidence everywhere. Piles of dead wood and trees stacked up one story high all over the place. Some areas even allow us to take some of the sectioned logs to take home for firewood.
It's an interesting article but a little too "LNT" we shouldn't mess with mother nature for me. The fact of the matter is we mess with mother nature by not allowing her to clean the forest through occasional natural fires, which causes many of our forest fires to burn out of control when they do ignite.
