The latter sprout up quickly, as all softwoods do, then rot just as quickly, prior to being cut down, or collapsing of their own dead weight, and they thereafter serve to feed the quality aforementioned survivors with deep roots to boot (unlike the shallow - rooted, soft -
wood ground surface feeders that lie dead), thus having their inferior
pulp turned into fertilizer, which thereafter serves to nourish the stump - survivors, which continue to win the evolution sweepstakes.
