broadleaves: A response calibration function for the other broadleaves

In THREC: Tree Height Response Calibration for Swedish Forests

A response calibration function for the other broadleaves

Description

This function performs a response calibration of the height function for other broadleaves. The other broadleaves include Black alder, Grey alder, Trembling aspen, Beech, Small-leaved lime, Rowan, Goat willow, Poplars, and other deciduous species. This function is not recommended for Oak species.

Usage

broadleaves(DATA)

Arguments

DATA	data frame containing at least yta, rev, t_l, dia, hdom, ddom, and hojd.

Value

data frame with estimated height

Note

yta: plot number, rev: revision, t_l: species code, dia: diameter at breast height, hdom: height of the tree with the largest diameter (ddom) regardless of the species (m), hojd: sample tree height with missing values. In cases where hdom is not present in the inventory data, site index (SI) can serve as an alternative, although the estimated height may exhibit slight variations.
