Healthy trees have a thick cambium and phloem layer that is usually able to pitch out beetle attacks. Overdense trees, which characterize stands that are not under active management, have a thin layer. A beetle attack does not get repelled as easily. Populations grow. Once the beetle population reaches a critical level, it is out of control, like a raging epidemic. Once a beetle attack is out of control, it stays out of control until it collapses of its own accord. There isn't a whole lot you can do about it. At this point, the only solution is to harvest dead and dying trees as fast as possible and start over. Sometimes you can start over with a different tree species, or a combination of species. Combinations are best because beetle populations are slowed down. in a tree to tree spread, and population growth rate is basically everything. Yes, to your question about whether this is mother nature at work. Mankind has an interest in getting value out of forests, so management is an effective way of preventing natural boom and bust cycles. Fire cycles are another of these phenomena. Put simply, nature likes to maintain a balance, and any time we do something that gets us out of balance she will compensate. Keeping fire out is one way of getting out of balance, but it can be compensated for with active forest management. Without active forest management nature does the job anyway, and we don't like the results. This is the reason why I am not going to kill that woodpecker that is pecking on my house. I will get him to quit by banging a pie pan or hanging up a scary windsock or hawk silhouette. Haven't seen my woodpecker today, so it's working. I hope. Beetle killed trees make good houselogs, if they are the right size. One reason why we're seeing so many log house manufacturers these days.
