Geological and climatic catastrophes such as volcanic eruptions, earthquakes, avalanches, meteors, floods, fires, and high wind also bring allogenic changes. Primary succession is the process bywhich pioneer species colonize an area otherwise uninhabitable for plant life and generate nitrogen for other plant communities. It starts out with bare rock, followed by lichens and mosses(as shown) and then, as the bare areas gather soil, plants such as star grass and red oat grass place from one stage of succession to another. The ecosystem changes with each new arrival.
