get_relative_cut_contribution {growR}

Relative cut contribution

Description

Get the fraction of the total annual harvested biomass that a cut at given DOY is expected to contribute.

Usage

get_relative_cut_contribution(DOY)

Arguments

DOY

Integer representing the day of the year on which a cut occurs.

Details

The regression for the target biomass is based on Fig. S2 in the supplementary material of Petersen et al. (2021).

Value

The fraction (between 0 and 1) of biomass harvested at the cut at given DOY divided by the total annual biomass.
