Tree Removal Parameters


Notes

For fire events, C is returned as charcoal. For Century, transferred N is mineralized. For DayCent fire, transferred N is ammonium.

Parameter Descriptions

Parameter Description Units Valid Values Default Values
EVNTYP Event type flag:
0 = cutting/removal event
1 = fire event
  0 or 1  
FD(1) Fraction of fine root component that dies. Pools are transferred to the soil litter metabolic and structural pools.   0.0 to 1.0  
FD(2) Fraction of coarse root component that dies. Pools are transferred to the dead coarse root pools.   0.0 to 1.0  
REMF(1) Fraction of leaf live component C and (N,P,S) removed from the system. Pools are transferred (1) for a cutting event, removed from the system; (2) for a fire event, to soil.   0.0 to 1.0  
REMF(2) Fraction of fine branch live component C and (N,P,S) removed from the system. Pools are transferred (1) for a cutting event, removed from the system; (2) for a fire event, to soil.   0.0 to 1.0  
REMF(3) Fraction of large wood live component C and (N,P,S) removed from the system. Pools are transferred (1) for a cutting event, removed from the system; (2) for a fire event, to soil.   0.0 to 1.0  
REMF(4) Fraction of fine branches dead component C and (N,P,S) removed from the system. Pools are transferred (1) for a cutting event, removed from the system; (2) for a fire event, to soil.   0.0 to 1.0  
REMF(5) Fraction of large wood dead component C and (N,P,S) removed from the system. Pools are transferred (1) for a cutting event, removed from the system; (2) for a fire event, to soil.   0.0 to 1.0  
RETF(1,1) Fraction of removed C (REMF(1) amount) that is transferred from the live leaf component to (1) for a cutting event, to litter, divided in to metabolic and structural according to fixed parameters SPL(*); (2) for a fire event, to soil.   0.0 to 1.0  
RETF(1,E) Fraction of removed (N, P, S) that is transferred from the live leaf component to the litter (cut) or soil (fire), where E = 2 for N, 3 for P, 4 for S.   0.0 to 1.0  
RETF(2,1) Fraction of removed C (REMF(2) amount) that is transferred from the fine branch component to (1) for a cutting event, to the dead fine branch pools; (2) for a fire event, to soil.   0.0 to 1.0  
RETF(2,E) Fraction of removed (N, P, S) that is transferred from the fine branch component to (1) for a cutting event, to the dead fine branch pools; (2) for a fire event, to soil, where E = 2 for N, 3 for P, 4 for S.   0.0 to 1.0  
RETF(3,1) Fraction of removed C that is transferred from the large wood component to (1) for a cutting event, to the dead large wood pools; (2) for a fire event, to soil.   0.0 to 1.0  
RETF(3,E) Fraction of removed (N, P, S) that is transferred from the large wood component to (1) for a cutting event, to the dead large wood pools; (2) for a fire event, to soil, where E = 2 for N, 3 for P, 4 for S.   0.0 to 1.0
