Description

Salvaged trees refer to standing trees killed by natural disturbances. This function enables to automatically build a CarbonProcessForest object that describes the decay of the salvaged trees, that are not harvested in the base case scenario, according to the decay function from Smyth et al. (2011) and the temperature-dependent decay function of the Canadian forest C budget model CBM-CFS3 (Kurz et al., 2009). It is assumed that standing trees (i.e., snags) starts decaying immediately after tree death until they fall to the ground (i.e., coarse woody debris (CWD)).

Usage

1
ProcessForest_SalvagedTreeLaganiere(kbs, kbd, Q10_kbs, Q10_kbd, CTR, mat, C0)

Arguments

kbs

numeric. The base decay rate of standing snags at a reference temperature of 10 degrees celsius (year^-1).

kbd

numeric. The base decay rate of coarse woody debris (CWD) at a reference temperature of 10 degrees celsius (year^-1).

Q10_kbs

numeric. The temperature sensitivity decomposition for standing trees according to Kurz et al. (2009).

Q10_kbd

numeric. The temperature sensitivity of decomposition for down woody debris according to Kurz et al. (2009).

CTR

numeric. Carbon transfert rate of snags (year^-1) according to Hilger et al. (2012).

mat

numeric. The mean annual temperature (degrees celsius).

C0

numeric. The initial quantity of carbon stored in woody debris (kg CO2 eq/GJ). The Intergovernmental Panel on Climate Change (IPCC) default value of 113.9 kg CO2 eq/GJ can be used (IPCC, 2006).

Value

Return a CarbonProcessForest object.
