Suppression Duration Mortality
This behavior evaluates mortality as a function of tree age. This is particularly useful for simulating suppression in seedlings.
Trees killed by this behavior will have a mortality reason code of "natural".
Parameters for this behavior
How it works
A tree's probability of mortality is:
The value for X0 is the age at which half of the maximum mortality rate is reached. Tree age is tracked using the Tree Age Calculator behavior. Initial conditions trees get a mortality of zero because their age is unreliable.
How to apply it
This behavior can be applied to trees of any species. Trees must also have the Tree Age Calculator behavior applied.
