Nudation is the growing up of new plant species in an area completely devastated by big natural calamities like volcanic eruption and meteor impact. Secondary succession is the growing up of new plant species in an area that has its pre-existing stable ecosystem partially affected by calamities like hurricane, landslide, etc.
