Example plots data set for CONIFERS growth model

Description

This a simple plots data.frame that contains basic plot attributes used in the CONIFERS growth model.

The plots data frame has 4 rows and 5 columns.

Usage

data(plots)

Format

This data frame contains the following columns:

plot
A numeric plot identifier.
elevation
Plot elevation, in feet.
slope
Plot slope, in percent.
aspect
Plot aspect, in degrees from North.
whc
Water holding capacity of the plot, in inches.
map
Mean annual precipitation, in inches.

Details

The example plot data represents plot level observations for a field sample that can be used to generate future forest conditions using the CONIFERS forest growth model. The data are in imperial units. The required values are the plot, elevation, and slope, and aspect measurements. Values that have not been observed, or are missing (e.g. whc and map), are denoted with an NA and can be imputed using the impute function
