Access External Data
This data set includes environmental, soil, and vegetation
information collected from 55 relevé plots at the Happy Valley
research site along the Sagavanirktok River in northern Alaska. To
complement formal relevé 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
relevé 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 relevé 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.
