Vegetation of Mount St. Helens


This dataset describes thirty years (1980-2009) of vegetation recovery from volcanic events on Mount St. Helens established from 92 permanent sampling plots and accounting for 85 species.


Dataset Location: Ecological Archives

Site Location:  Mount St. Helens

Sites Georefferenced: Yes

Timespan: 1980-2009

Methods: Circular plots (250m2) are established based on the impact types from the volcano blast arrayed along transects. Additional transects are established from the center pole of the circular plot at 90o angles. Individuals were identified within quadrats placed along these secondary transects.

Data Collected: species, richness, plot cover, diversity, evenness, mean species frequency
