A pine tree very specifically only grows its vegetative part a few meters from the very top of the tree line. That's a very well defined niche.
A cave is mostly only inhabited by fungus. There you go, a niche only inhabited by a single kind of organism, and that's not even difficult to find.
Anyways, basing your behavior on how "things are in nature" is as insane as eating bark because you see a bear do it. It's stupid because analogies do not translate at all between things so distant as human and animal feeding patterns, or - in your case - yellowstone forest and business markets. Unless your CEO is Yogi Bear.
