Figure 5
Richness (mean number of plant species ±1 SE) of plant communities in three habitat types at Mount St. Helens National Volcanic Monument sampled between 22 and 25 July 2008. All plant species, including unidentified ferns and grasses (which were categorized to morphospecies), found within the 0.5 m2 sampling quadrats were used in plant richness calculations. Different letters above the bars indicate significant differences () between habitat types.
