Vascular Plant Species Cover for the Shoshone National Forest, Wyoming, USA
Description
Percent cover (in codes) for 368 vascular plants on 150 375m^2 sample plots
stratified across the Shoshone National Forest, Wyoming, USA. Plots were chosen at
random from a larger dataset.
Usage
data(shoshveg)Format
A data.frame with sample plots as rows and species as columns. Sample plots match the ‘shoshsite’ dataset.
The cover of all vascular plant species was recorded according to the following scale: present but < 1% = 0.1, 1-5% = 0.5, 5-15% = 1.0, 15-25% = 2.0, 25-35% = 3.0, 35-45% = 4.0, 45-55% = 5.0, 55-65% = 6.0, 65=75% = 7.0, 75-85% = 8.0. No species exhibited greater than 80% cover in the data set.
Note
The data were derived from a multi-year effort by numerous scientists and field technicians. The project was directed by Kent Houston, Soil Scientist and Ecologist, Shoshone National Forest
