This article is sorta right, but not really.
YES wildfires are an integral part of boreal ecology - Tamaracks, as an instance. do not go to seed without fire. And everyone wants Tamarack / Larch, which is just as desirable as Douglas Fir.
The thing his article does not include or consider is the increased population and use of the forests since Mark Twain's day. In that day, suppression was not possible in any great degree... But the investment and population of the western forests were also minimal.
The natural forest has always been 'Let it burn', and is to this day.
That's not what we are talking about. Logging operations provide a wide buffer around populated areas where the forest is managed. Because the lion's share of the populous is in those areas, the populated and invested places are rendered relatively fire free - Because logging operations and roads provide access, remove ladder fuels, open clear cuts which act as barriers to fire...
MOST of the accidental fire happens where people are. Managed forests and fire suppression properly prevent the lion's share of those accidental fires (because it is people starting those fires where people are) or limits their size and longevity.
Equally, the lion's share of human investment is also therewith protected. Allow the forest to be natural right up to all those gentleman farms and hollers is just asking for trouble.
And millions of board feet of lumber burning up instead of being farmed is just stupidity.
