Historical effects of dissolved organic carbon export and land management decisions on the watershed-scale forest carbon budget of a coastal British Columbia Douglas-fir-dominated landscape

Table 4 Calibrated CBM-CS3 parameters partitioning C losses from decaying slow aboveground (AG) and belowground (BG) DOM pools to the atmosphere (fraction to atmosphere) or as dissolved organic carbon (DOC) (fraction to DOC)—modelled and observed values of mean and mean ha⁻¹ Mg of carbon 1996–2012 for Rithet, Judge and Council catchments used to derive parameter values

Catchment	Slow DOM pool	Fraction to atmosphere	Fraction to DOC	Modelled value		Observed value
