Mount St. Helens (volcano in Washington state) erupted in 1980. What kind of succession had to occur after its eruption?
primary succession
secondary succession
Some parts had to undergo primary succession, while other areas underwent secondary succession.
Succession cannot occur after such an intense disturbance.
The correct answer is primary sucession
Primary succession is one of two types of biological and ecological succession of plant life, occurring in an environment in which new substrate devoid of vegetation and other organisms usually lacking soil, such as a lava flow or area left from retreated glacier, is deposited.
