Slide1 : Australian Greenhouse Office National Carbon Accounting System Carbon Accounting Model for Forests (CAMFor)


CAMFor Model : CAMFor Model C1 - Carbon movements during a year (no harvest, thinning or fire) C2 - Carbon movements due to harvest or thinning C3 - Carbon movements in a stand-replacing fire C4 - Carbon movements in regenerating (crown and ground) fire CAMFor is a spreadsheet model for determining carbon masses in forest stands and forest estates. Four key carbon movements are modeled over time to derive the estimates for carbon masses in a stand. CAMFor computes carbon masses in tonnes/hecatre over the life of the stand. CAMFor provides for the accumulation of stands into groups of similar stands and then into forest estates. Application Models


Application Overview : Application Overview CAMForEstate.xls CAMFor.xls A Stand Type Group is defined by Species Parameters, Tree Growth Rates, Soil Carbon, Thinning Regime, Management Regime CAMFor.xls CAMFor.xls Species Parameters Growth Rates Soil Carbon Thinning Regime Management Regime Stand 1 Stand 2 Stand 3 Stand n Estate 1


Slide4 : Carbon Movement Models No thinning or fire Thinning Stand-replacing fire Ground or Crown/Ground fire The four key carbon movements affecting the end-of-rotation carbon mass in a stand


Slide5 : Carbon Movement Models No Fire or Thinning


Slide6 : Carbon Movement Models Thinning


Slide7 : Carbon Movement Models Stand-Replacing Fire


Slide8 : Carbon Movement Models Crown & Ground Fire


InputManagement Regime : Input Management Regime Input Data: Management Information Each stand can have unique management properties that reflect initial conditions & site specific conditions


InputSpecies Parameters : Input Species Parameters Input Data: Species Information The species that populate each stand will have unique properties that effect carbon flows through the stand over time


InputSoil Carbon : Input Soil Carbon “TIME” Input Data: Rotation x Soil Carbon


InputGrowth Rates / Mass Increase : Input Growth Rates / Mass Increase Input Data: Growth rates “TIME” The growth rate of the stand will have a direct effect the carbon mass accumulation in the stand. CAMFor has two methods of estimating yearly increase in carbon mass - Stem Volume Flux Above Ground Mass Flux


InputThinning History / Weight Fraction : Input Thinning History / Weight Fraction Input Data: Thinning fractions x Allocation Fractions “TIME” The stand thinning regime (frequency, intensity, end-use) is critical in the estimation of carbon mass over time.


SensitivityParameter Influence : Sensitivity Parameter Influence Parameters in decreasing influence on the Total Carbon Mass / Hectare in a particular rotation (year 65) for a particular stand group


Slide15 : Sensitivity Carbon Mass Confidence Increasing likelihood of a Total Carbon Mass / Hectare at a particular rotation (year 65) for a particular stand type group


OutputStand Type Group : Output Stand Type Group Input Data Sensitivity Carbon Mass Confidence Carbon Mass Influence A ‘Stand Type Group’ is a group of similar stands (same species and and management regime).
