Stuff like this gives a satisfying sense of restoring order. This is the way things were before dramatic human intervention. The ironic part is that the restoration itself requires human intervention. I always find myself wondering what would happen if humans just disappeared overnight. How things are now would be the starting point of the "new natural." Ecosystems probably wouldn't return to the way they were before Europeans arrived; they would proceed along some new pathway. Not least because of how much we've already changed the climate, and the species we've introduced. Then I think about a time 100,000 years after this hypothetical disappearance of humans and picture conservationists of whatever species, aliens maybe, concerned with protecting the indigenous species they found like wild cows, Himalayan blackberry and kudzu, that are now endangered by overdevelopment and global cooling.

Anyway it would be really interesting to be able to chart the changes to this microcosm of a prairie ecosystem over thousands of years if there were no human intervention whatsoever.
