tree.age {sitreeE}

EStimation of individual tree age

Description

Estimates individual tree age of trees within a plot based on basal area, site index, species, and development class.

Usage

tree.age(stand.age.years, plot.id, tree.BA.m2, dbh.mm,
SI.spp, SI.m, spp, dev.class, apply.correction = TRUE)

Arguments

stand.age.years

The age of the stand in years.

plot.id

The unique ID of the stand

tree.BA.m2

A vector with the basal areas of each tree in m2.

dbh.mm

A vector with the DBH in mm of each tree.

SI.spp

Species for which SI has been calculated (1, 2, 3).

SI.m

Site index (SI) in m.

spp

Species group classification.

dev.class

Development class.

apply.correction

TRUE/FALSE. If a correction to age should be applied

Value

A vector with the estimated ages of trees

Examples

tree.age(stand.age.years = 40,
        plot.id = c(1,1), tree.BA.m2 = c(0.05, 0.5),dbh.mm
        = c(50,150), SI.spp = 2, 
        SI.m = 11, spp = c(1,1), dev.class = 3, apply.correction = TRUE)
