Just adding this in to this thread, so that everything is in the same place.
_______________________________________________
Well, I watched the Nova "Megafire" program.
Although I had high hopes (the scientific research being done, as presented in the program, I found particularly interesting), overall I found the program incomplete, too brief, simplistic, and ultimately disappointing.
Why do I feel this way?
The three major California fires referenced in this program - the Camp Fire, the Tubbs Fire, and the Carr Fire - started, and mostly burned, in chaparral scrub land, and not in "forests" per se (tall conifer forests, as defined by the program).
Although I might have missed it, I don't think I heard the word "chaparral" mentioned even once. Dense, uncontrolled growth of chaparral here is one of the primary reasons California fires are so destructive.
Remember the bit in the program about the massive "fire tornado" they showed whirling around in the Carr Fire (Redding, Ca.)? That wasn't tall forest conifers burning, that was chaparral (I live fairly near Redding, so know it well). Redding isn't in the mountains (conifer tree country), it is in the Central Valley (chaparral country).
I am putting a bit of what I wrote on the "Fire Near Anne" thread (this part is from page 7 of that thread) below my signature, should anyone be interested. I talk a little bit about our weather here, and California's problem with chaparral. One thing that was mentioned (again, in reference to conifer forests) was that thinning must be done frequently for it to be effective. Because thinned and cleared areas just sprout new vegetation.
This continual "thinning" needs also to be done with chaparral scrub lands. The problem being, chaparral is much more difficult to thin, grows back much more quickly than do conifers (so needs to be "thinned" more frequently), and - and this is the main kicker - "thinned" chaparral has no economic value for resale. Whereas conifers, even quite small ones (think treated fence posts), can be cut as part of a thinning process, and then sold.
Can I see the logging companies here lining up to get their permits to "thin" tall-tree conifer forests? Absolutely. Can I see the same companies lining up to get out there and thin the chaparral? Never happen.
So long as one major causal element of the California wildfire problem is ignored (chaparral), it is highly unlikely that any real solution will ever be found.
Just my 2cents.
