Gompertz Density Self Thinning MortalityThis 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". Parameters for this behavior
How it worksThe 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:
How to apply itThis behavior can be applied to trees of any species.
