The data in this database describe the permanent plots collected on Mount St. Helens from 1980 to 2005 by Roger del Moral. Plots occur in mildly impacted tephra, scoured sites on the southwest and northeast portions of the cone, on lahars on the southwest side and devastated sites on the Plains of Abraham, Pumice Plain, Pine Creek Ridge, Toutle Ridge and Studebaker Ridge. These plots permit monitoring of the development of vegetation in a detailed way. Data include species composition, richness, cover, frequency and diversity for each year sampled.

The data from these plots have formed the basis of several papers. Citations are available at: http://faculty.washington.edu/moral/publications.html
