height_param: Estimates total individual tree height in function of its DBH...

In sgezan/Nothopack: G&Y Forest Simulator for Roble-Rauli-Coigue Stands in Chile

Description

Estimates individual tree height form a model of stand-level parameters: dominant height (HD, m), quadratic diameter (QD, cm), and diameter at breast height (DBH, cm).

Usage

height_param(DOM.SP, ZONE, HD = NA, QD = NA, DBH = NA)

Arguments

DOM.SP	Dominant species (1: Rauli, 2: Roble, 3: Coigue) of the stand
ZONE	Growth zone (1, 2, 3, 4) of the stand
HD	Dominant height (m) of dominant specie in the current stand
QD	Quadratic diameter (cm) of the stand
DBH	Diameter at breast height (cm) of tree

Value

Individual total tree height HT (m)

Examples

# Example: Estimates HT for trees with DBH=24 for different stands
(HT <- height_param(DOM.SP=2, ZONE=2, HD=15, QD=12, DBH=24))
(HT <- height_param(DOM.SP=2, ZONE=2, HD=15, QD=18, DBH=24))
(HT <- height_param(DOM.SP=2, ZONE=2, HD=19, QD=12, DBH=24))
(HT <- height_param(DOM.SP=2, ZONE=2, HD=19, QD=18, DBH=24))
