This result group contains: Results that describe risks of disturbances (forest damages) as a function of forest characteristics. Results include data for each treatment unit, alternative and time period. It is currently possible to estimate the risk of disturbances from storm and Spruce bark beetle respectively, presented as indices (0-1). Also, estimations regarding Root rot have been moved to this Result variable category. Here, both Before- and After-values can be found, regarding estimations before and after any simulated treatment in the current time period.
| Variable name | Unit | Description |
| Root Rot Potential Basal Area | m2/ha | Basal area of trees predicted having root rot |
| Root Rot Potential Volume | m3sk/ha | Volume of trees predicted having root rot (not same as rotten volume!) |
| Root Rot Stems | trees/ha | Predicted number of stems affected by root rot |
| Spruce Bark Beetle Index | 0-3.46 | Risk Index For Spruce Bark Beetle Damage. The risk index is developed by Michelle Nordkvist and is a measure of the relative sensitivity/susceptability for a stand to be attacked by spruce bark beetles based on stand and climate variables. The risk index can be used as a basis for comparison between stands with different characteristics, climate or applied management, but not as an absolute measure of risk. |
