Aliens in the eco-system cause imbalance, therefore cause damage. But that is such a complex and hard-to-control issue compared to things like logging. Because logging is much more deliberate and "man-made".

I live in northern Canada and there are forests/bush's everywhere. So I guess I'm pretty lucky for that. Maybe down the line, the types of trees you've mentioned will have their own "habitiats" like endangered species. Unless they haven't already've done that.

An image that comes to mind comes from The Simpsons, where in the future there's a hologram of a tree in memorium for a real tree. Hopefully that won't be the case.
