NV Factor for Natural Value -
L Factor for Landscape Value -
S Difficulty Factor -
L Factor for Time -
I Factor for Indirect Influence -
T0 before influence/action -
T1 after impact/action -
U Present value CLIMB units
V Fabricated CLIMB units by creating biotopes
X CLIMB units lost through deterioration of the biotope
Y CLIMB units lost through indirect impact
Z CLIMB units lost through indirect impact
