Description

Description of a forest stand

Usage

emptyforest(ntree = 0, nshrub = 0)

# S3 method for forest summary(object, SpParams, mode = "MED", ...)

# S3 method for summary.forest print(x, digits = getOption("digits"), ...)

Value

Function summary.forest returns a list with several structural attributes, such as the basal area and LAI of the forest. Function emptyforest returns an empty forest object.

Arguments

ntree, nshrub

Number of tree and shrub cohorts, respectively.

object

An object of class forest has the following structure:

  • treeData: A data frame of tree cohorts (in rows) and the following columns:

    • Species: String with species (taxon) name or a non-negative integer for tree species identity (i.e., 0,1,2,...) matching SpParams.

    • Height: Total tree height (in cm).

    • DBH: Tree diameter at breast height (in cm).

    • N: Density (number of individuals/hectare) that the measured tree represents.

    • Z50: Depth (in mm) corresponding to 50% of fine roots.

    • Z95: Depth (in mm) corresponding to 95% of fine roots.

  • shrubData: A data frame of shrub cohorts (in rows) and the following columns:

    • Species: String with species (taxon) name or a non-negative integer for shrub species identity (i.e., 0,1,2,...) matching SpParams.

    • Height: Average total height of plants (in cm).

    • Cover: Percent cover.

    • Z50: Depth (in mm) corresponding to 50% of fine roots.

    • Z95: Depth (in mm) corresponding to 95% of fine roots.

  • herbCover: Percent cover of the herb layer.

  • herbHeight: Mean height (in cm) of the herb layer.

SpParams

A data frame with species parameters (see SpParamsMED).

mode

Calculation mode, either "MED" or "US".

...

Additional parameters for functions summary and print.

x
