Happy Valley Permanent Vegetation Plots
https://data.eol.ucar.edu/dataset/106.ARCSS083

Summary
This dataset contains Happy Valley Permanent Vegetation Plots data, including
environmental, soil, and vegetation information collected from 55 releve plots
at the Happy Valley research site along the Sagavanirktok River in northern
Alaska. To complement formal releve sampling of vegetation during the period
July 18-27, 1994, the investigators described each study site (including site
topography, surficial geology, estimated snow duration, soil moisture, thaw
depth, and signs of disturbance, among other parameters) and collected soil
samples adjacent to the releve plots for laboratory analyses. Soil analyses
include measurements of soil chemistry, pH, organic matter content, and
texture (percentages of sand, silt, and clay). Ordination analysis displays
releve data in two-dimensional space according to species similarity. Results
from ordination reveal that three environmental variables -- stability,
exposure, and soil moisture -- significantly affect vegetation composition.
