In Glacier, over the last 10 years now...basically the entire Northwest side (250,000 acres) has burned. The oldest of these burns (Red Bench, 1988) has fantastic growth, green green green with standing tall dead trees around...it's facinating...the cycle.
Our HUGE burns were in 1967, and biggest burn (400,000 acres) in 1923. So, these fires were due...but in many cases magnified by the fact that small(er) fires in the past were surpressed. Our best fire line to the north on this fire was the 2001 Moose fire scar. And logepole trees litterally explode when they burn hot...it's wild...kind of like their cones which open up to intense heat and start the process over again...while the big ponderosas and larch....well they make for a erie mosaic of 400 foot flames. Give it 2 years and the under growth will be nice and green....15 years nice 15 foot trees..and when you are retired...there will be noticable snags...but it will be look like it did today...where the dead tree from 1967, is the tree of 2003.
As far as old growth...the way these forests get that way...and stay protected naturally is to be naturally thinned. Fewer trees per acre, and when trees have more room they get bigger and more resistant. When fires come through less dense growth, ground fire is usually what it is...cleaning the forest floor and the trees live...unless crowning/torching occurs...which is evident in hot fires.
Today with supression tactics...and structure support, these forests don't develop very well this way...they become thick...thicker and thickest, and when they start on fire...they are hot dry fires. Proper management of forests around communities/towns could prevent these mass, uncontrollable fires around populated areas. THere is a fine line between how and where it should be done...both environmentally and economically. Besides the fact that the definition of a "healthy forest" varies on a given day. (This article is in the same TIME magazine I mentioned in the opening post)
It's a natural process...it just sucks to be in the way.
