Description
The coniferous forests of the Shoshone National Forest range from lower
elevation woodlands dominated by Pinus flexilis, through forests of
Pseudotsuga menziesii, Pinus contorta, Picea engelmannii, Abies lasiocarpa and
Pinus albicaulis with increasing elevation (Steele et al. 1983). One
hundred and fifty sample plots were chosen at random from a larger set for this
data set; the larger set was stratified by elevation, exposure, surficial
geology, and geographic distribution.

Format
A data.frame with sample plots as rows, and site variable as columns. Variables
comprise:
elevation elevation above sea level in meters
aspect compass orientation of the site in degrees
slope slope steepness in percent
av aspect value: (cosd(aspect-30)+1)/2
swb site water balance: a tipping bucket model of water-year soil water
sprppt spring precipitation in cm
sumppt summer precipitation in cm
autppt autumn precipitation in cm
winppt winter precipitation in cm
sprtmp spring mean temperature degrees C
sumtmp summer mean temperature degrees C
auttmp autumn mean temperature degrees C
winppt winter mean temperature degrees C
sprpet spring potential evapotranspiration in cm
sumpet summer potential evapotranspiration in cm
autpet autumn potential evapotranspiration in cm
winpet winter potential evapotranspiration in cm
sprrad spring direct and diffuse solar radiation (correcting for topographic
shading)
sumrad summer direct and diffuse solar radiation (correcting for topographic
shading)
autrad autumn direct and diffuse solar radiation (correcting for topographic
shading)
win winter direct and diffuse solar radiation (correcting for topographic
shading)
ffd frost free days
dday degree days heat sum
tcol mean monthly temperature of the coldest month
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. The site data were calculated primarily
by Dr. Niklaus Zimmermann, WSL, Birmensdorf, Switzerland
