So this needs to be stressed: the only reason the area around Starbase is protected habitat is because SpaceX built Starbase there. Because space launches fall under FAA and thus Federal regulation, the area around them becomes Federal land and subject to Federal environmental review and protection. This is the same reason Cape Canaveral is surrounded by protected wetlands - it's because the Cape Canaveral launch complex is there.

But that's predicated on the facility existing. If SpaceX hadn't bought that land - and they did buy it - it was for sale - then those wetlands would not be protected habitat at all.
