Summary

contains an excel format and shapefile format of the vegetation survey data collected within Humboldt Bay during the summer of 2012. We recorded vegetation data within a 0.25 m2 quadrat concurrently with elevation surveys. Data were taken at every fourth (25%) elevation point (n=740 quadrats; Fig. 4). We measured height (mean and maximum, measured within 0.05 m) and visually estimated percent cover for each species within each quadrat. This allowed us to develop a relationship between plant species, elevation and tidal datum across all sites. We also characterized the most common species, which were defined as those found at>10 % of the plots. Plant species frequency was plotted relative to MHW. This comprehensive vegetation dataset [...]
