Disturbance behaviors simulate different kinds of forest disruption. These behaviors cause tree damage and death due to a variety of processes.
| Behavior | Description |
|---|---|
| Competition Harvest | Performs harvests in a way that preferentially removes the most competitive individuals in a plot. |
| Generalized Harvest Regime | The behavior itself decides when harvests will occur and how much to cut based on total plot adult biomass, then chooses trees to cut with the help of a preference algorithm. |
| Harvest | Implements complex silvicultural treatments. |
| Harvest interface | Allows SORTIE to work directly with an external harvesting program. |
| Insect Infestation | Simulates an insect outbreak by choosing and marking infested trees. |
| Episodic mortality | Allows you to replicate tree-killing events with the same level of control you have when defining Harvest events. |
| Random browse | Simulates random browsing from herbivores. |
| Storm disturbance | Simulates the effects of wind damage from storms. |
| Storm damage applier | Decides which trees are damaged when a storm has occurred and how badly. |
| Storm damage killer | Kills trees damaged in storms. |
| Storm direct killer | Kills trees based on storm severity, without an intervening damage step. |
| Selection harvest | Allows you to specify target basal areas for a tree population as a method of harvest input, instead of designing specific harvest events. |
| Windstorm | Kills trees due to storm events. |
