An interesting case study about this is the Bavarian Forest National Park. In the 80s, several major storms caused a huge amount of trees to die, and there was a decision made to not intervene in the forest ecosystem and leave the dead trees instead of removing them. Then in the 90s because of this and other reasons that created a favorable environment for the bark beetles, there was a massive spread of them and large parts of the forest died. The national park management continued the policy of not intervening in the forest ecosystem, which was met by pretty heavy criticism from parts of the population. However it seems to have worked out in the end, as the forest is now starting to regenerate.
