This behavior calculates the probability of mortality of an individual tree as a function of the density of conspecific neighborhood trees.
Trees killed by this behavior will have a mortality reason code of "natural".
Parameter name | Description |
---|---|
Gompertz Density Self Thinning - G | G in the function for probability of mortality. |
Gompertz Density Self Thinning - H | H in the function for probability of mortality. |
Gompertz Density Self Thinning - I | I in the function for probability of mortality. |
Gompertz Density Self Thinning - Min Neighbor Height (m) | Minimum height for conspecific neighbors to be counted towards density. |
Gompertz Density Self Thinning - Neighbor Search Radius (m) | Radius for which to search for conspecific neighbors. |
The density of conspecific neighbors is the number of stems per square meter of trees above the height set in the Conspecific Tree Minimum Neighbor Height (m) parameter, within the radius from the target tree's location set in the Conspecific Tree Search Radius (m) parameter.
The probability of mortality is calculated as follows:
where:
This behavior can be applied to trees of any species.
