Disturbance Risk Results

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. Note that overstorey trees are included in the calculation of the index. [1]
Storm index (Lagergren)	0-1	Storm index according to Lagergren et al 2012 [2]
Storm index (Valinger)	0-1	Storm index according to Valinger et al 2006 [3]
