Yes, there are several hidden areas in SW, and they’re very well done. Unfortunately, finding them doesn’t contribute anything but a sense of pride and accomplishment. I agree entirely about wildlife. It would be fantastic to fight off the occasional Scrab or Fleech, or see a pack of wild or farmed Elums adding even more life to the great environments. There are wild Slegs already, though, as well as Live Ammo, birds, and flies.
Interrogation and escorts would bring some very welcome variation to the missions.
Here is a map showing the Elum’s Spine mountain range:
