Difficult part of trying to do this is in areas where you would really want to burn there are often regulations against doing so. Or regulations limiting burns quite a bit.
Also while controlled burns sound good in theory (I am actually an advocate of controlled burns), they can easily get away from you if you don't know what your doing. If you start a burn and it gets away from you and spreads to neighboring land you can be held financially and criminally responsible.
If you remember the big to do in OR with the stand off, the family who was the focal point of the original protests were in their situation due to 2 illegal burns they did. I am not wanting to get into the
politics of the event, just pointing out the legal repercussions of burning. That event got national coverage unlike the thousands of smaller cases of ranchers and farmers in the west who get penalized for burns.
Is burning a good practice? It can be if done properly.
Should people do burns? In general I would highly suggest folks limit their burns done by themselves to very small and do plenty of research ahead of time of the legalities. I would suggest actually finding professional people to come in to help with any large scale burns, like clearing dead
wood from a forest. There are some groups who do do this. They are often a traveling business, who can range many states as the optimal fire season changes region to region.
The big take away, is before even considering a burn look into the laws of your area. Find out what you are legally allowed to do and what you aren't. Using fire to manage your land is not worth you loosing your land or even your
freedom over.
