Stochastic mortality

This behavior produces a background mortality rate. Individuals within the pool of trees to which this behavior applies are randomly selected to die.

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

Parameters for this behavior

Parameter name	Description
Background Mortality Rate	The proportion of trees that die each year, as a value between 0 and 1.

How it works

For each tree, a random number is compared to that species's Background Mortality Rate parameter to determine if it falls in the pool of trees that die.

How to apply it

This behavior can be applied to seedlings, saplings, and adults of any species.
