BC mortality

BC mortality is a growth-based mortality behavior.

Trees killed by this behavior will have a mortality reason code of "natural".

Parameters for this behavior

Parameter name	Description
Light-Dependent Mortality	Light-dependent mortality.
Mortality at Zero Growth	Mortality rate at zero growth.

How it works

The BC mortality model evaluates the following function to determine the probability of a tree's mortality:

m = 1 - exp(-(T * m₁) * exp(-m₂ * G))
where:

m is the probability of mortality
T is the number of years per timestep
m₁ is the Mortality at Zero Growth parameter
m₂ is the Light-Dependent Mortality parameter
G is amount of radial growth, in mm/yr, added to the tree's diameter during T

BC mortality is described in Kobe and Coates 1997.

How to apply it

This behavior can be applied to seedlings, saplings, and adults of any species. Any tree species/type combination to which it is applied must also have a growth behavior applied.
