Mount St. Helens Vegetation Succession

DB Code: 
TV071
Abstract: 

The data in this database describe the grid plots collected on Mount St. These plots permit monitoring of the development of vegetation and spatial expansion in a detailed way. Data were obtained in 100 m2 plots arranged in a contiguous grid. Data include species composition, richness, index of cover (a logarithmic scale), frequency of each index type and diversity. The metadata include a conversion scale between index score and percent cover. Summaries are found at: http://protist.biology.washington.edu/delmoral/grids.html

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

Purpose: 

This database was developed to document the recovery of vegetation and spread of populations. A major goal is that other researchers will use the data for meta-analyses and to test particular hypotheses.
