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)
