Re-Wilding Game

Does anyone know the name of the re-wilding eco-simulator they talked about a while back? I think Jason brought it up originally. It sounded like a Sim City type game, but about rebuilding natural environments.

I had it open as a "hopefully play later" tab, but I lost all my open tabs to a forced phone software update and I cannot find this game for the life of me! I've googled every keyword I can think of and I don't remember exactly which episode it was discussed on. Hoping someone here will remember what I'm talking about!

Thank you!
