So your saying there is some kind of park that is able to power itself efficiently enough to provide it's self energy to support an ecological subsystem in region that is completely unrelated to regular environment in which these organism exist? If so, perhaps I may have an answer to your question. Here is some food for thought, what if there could be a possible quantum rip in the universe that could potentially cause unsystematic or indiscriminate events to occur as if they were influenced by the simple action of belief or human thought. This being the case, perhaps this quantum park has the ability to materialize it's self according to the manifested collection of thoughts and beliefs from nearby residing humans. Theoretically, the only possible way this could happen would have to be under strict conditions, under these conditions would have to exist an individual that posses an unnatural amount of psychic and universal energy that discharges it's self into a shell or some kind of supernatural being that has the ability to think as a sentient being. I admit I may have strayed a bit much into my imagination but if that answers your question then I hoped it helped.
