7.2.3 Carbon Loss Due to Harvesting
According to Papale et al. ( 2005 ), the losses of carbon (C wood utilization ) from for-
ests due to forest harvesting can be assessed as follows:
C WOOD UTILIZATION = HV · K 1 · BD · K 2 [T]
(7.1)
where
HV = harvested wood volume [m 3 ];
k 1 = average expansion coefficient to take into account the wood residuals left in
the forest stands (cutting woody debris); this coefficient was set equal to 1.176,
according to Corona and Nocentini ( 2002 );
bd = average wood basal density of forest tree species in Italy, set equal to
0.65 t m 3 , according to APAT ( 2003 );
k 2 = average carbon content per unit of wood biomass of forest tree species
[t t 1 ], set equal to 0.5 according to APAT ( 2003 ).
