Natural colonization

Natural colonization is a process where a species from one planet introduced to another planet either fills a niche or replaces an existing species. Natural colonization leads to a situation where the foreign species becomes embedded in the ecosystem of the other planet, or if sufficient other life forms of its native planet are also present, will create a new ecosystem.

Natural colonization of Folkvangr was considered only slightly intrusive, hindering some non-essential species slightly by habitat concurrence. A very visible form of natural colonization on the planet is the introduction of trees.
