>I guess the speed of tree growth might be a bottleneck. Also depends on what grows back in their place. For example, re-forestation efforts in places like Ireland have lead to an "ecological dead zone" [0] due to the choice of the trees that have been planted, the Sitka spruce and its sheddings offering or removing habitable areas for animals to prosper. Without an expensive and concerted effort to clear the floors of ash and re-plant animal-friendly, indigenous fauna I would imagine we won't see much of a recovery in our lifetimes, if ever.
