I haven't read this whole thread, so forgive me if this has been suggested before.
I'd like to see a way for animals to stick around a bit longer. By the time barbarian cities are spawning and many cities are settled/conquered most of them are gone due to loss of land.
One possibility is to increase the spawn a bit, or allow a small chance for a random spawn inside your borders on unimproved tiles, so long as a unit is not occupying it.
Another suggestion is to modify the Nature preserve improvement, make it buildable at a much earlier tech (classical era at least) It gives a couple coins as before, but also causes the terrain it was built on to spawn a random animal appropriate to the terrain, feature and/or bonus that the preserve was built on top of. It will do this even if it is inside your borders, and thus the animal can then be harvested/subdued. It should not spawn an animal if a unit of any type is already sitting on the tile.
A water version of the same could also be made for a later tech level.
In essence in exchange for the chance for animal spawns on that tile, your giving up the ability to build other improvements on it.
I haven't finished a game as far as tourism yet, so I don't know what the current nature preserve does, maybe it actually does this, but it has no descriptions so I am not sure.
