So, in the movie, Jurassic World, they mention "Invisible Fences", which are barriers that function similar to shock collars with dogs, using the dinosaur's chips to not let them pass certain areas.
I suggest adding these fences, as they could go through terrain obstacles, being placed in a manner similar to pylons. The downside to them would be they NEED POWER to be active, and if they lose power, it's as if it's an open gate, or a broken fence. It could use double the power of a normal electric fence potentially, but I think it would be a good addition, so you can have Mixed Exhibits without worrying too much, as the invisible barriers would not cut down on the size of Habitat Requirements (maybe, I don't know.), but it would also not effect Social or Population, meaning it can't be used to isolate an overpopulated pen.
