biomass.birch.S2014: Implements biomass functions for birch for Norway from Smith...

In sitreeE: Sitree Extensions

Description

Implements biomass functions for birch for Norway from Smith et al (2014, 2016). Total biomass aboveground does include stump calculated using biomass.birch.M1988. Total biomass belowground does not include stump.

Usage

biomass.birch.S2014(dbh.cm, H.m)

Arguments

dbh.cm	dbh (diameter at breast height) in cm.
H.m	Tree height in meters.

Details

It uses stump.roots from biomass.birch.M1988 to calculate aboveground biomass (in kg) and belowground biomass (in kg). Aboveground biomass is calculated as Smith's aboveground biomass (2014) + stump.roots. Belowground biomass is calcualted as Smith's belowground biomass (2016) - stump.roots.

Value

Returns a data.frame with the following biomass components: biomass.total.kg, biomass.aboveground.kg.S2014, biomass.belowground.kg.S2014, biomass.belowground.kg, biomass.aboveground.kg, living.branches, dead.branches, stem.wood, stump.roots, bark, usoil, rot1, rot2, foliage)
