Conspecific Tree Density Dependent Seed Survival
This behavior assesses seed survival as a function of the local density of conspecific trees. This behavior is very similar to Density Dependent Seed Survival.
Parameters for this behavior
How it works
This behavior takes the seeds that have been dispersed to each grid cell of the Dispersed Seeds grid and calculates how many will survive. The survival probability is a function of the density of 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 set in the Conspecific Tree Search Radius (m) parameter.
The number of seeds that survives is calculated as
Once the number of surviving seeds has been determined, the behavior assigns that number back to the Dispersed Seeds grid cell.
How to apply it
Apply this behavior to seeds of your desired species. Any species to which it is applied must also have any disperse behavior applied.
