Vmodule: Estimates stand-level volume based on stand-level parameters

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

Description

It reads stand-level input variables (BA, HD and PNHAN, PBAN) to estimate stand-level total volume with bark (m3.ha). There are two models: 1:requires BA, HD, PNHAN and PBAN, and 2:requires BA, HD, PNHAN. The later model is more stable.

Usage

Vmodule(BA = NA, HD = NA, PNHAN = NA, PBAN = NA)

Arguments

BA	Basal Area (m2/ha) of the current stand
HD	Dominant height (m) of the current stand
PNHAN	Proportion of Nothofagis trees in the stand (optional)
PBAN	Proportion of Nothofagus basal area in the stand (optional)

Value

Total volume with bark (m3/ha) for the current conditions across all species

Examples

# Example 1: Predicts volume with PNHAN and PBAN
Vmodule(BA=32, HD=15.9, PNHAN=0.81, PBAN=0.90)

# Example 2: Predicts volume with PNHAN
Vmodule(BA=32, HD=15.9, PNHAN=0.81)

# Example 3: Predicts volume
Vmodule(BA=32, HD=15.9)
