Termite Mounds Are Spaced So That They Don't Interfere

The termite mounds are spaced as if they were almost subsessive, and you were trying to space them very evenly and regularly. They organize themselves by slowly moving and killing other colonies and fighting. A bigger colony with more termites is going to displace a smaller colony. It's very easily just obliterates it. And so you can never have small colonies. They don't last very long. You end up with basically all, when you reach some form of equilibrium, all colonies have to be roughly similar sizes otherwise the bigger one will win.
