Secondary Succession can occur after Primary Succession, or can occur as a result of a natural disaster, such as a forest fire or a flood. Secondary Succession usually is the growth of grasses and other small plants. A forest that is destroyed by a natural disaster still usually has small plants or at least soil, which is what Primary Succession makes. That means that if a natural disaster leaves only soil, the area where it occurred won't have to go through the long process of Primary Succession again.
Secondary Succession can make the soil fertile enough to allow larger plants and bushes to grow, all eventually leading up to a forest with large trees.
