* Metric Name: Risk of Tree Dieoff During Drought *  

* Tier: 1  

* Data Vintage: 12/2021  

* Unit Of Measure: Index, low to high vulnerability  

* Represent element and pillar: Yes  

* Type and distribution of data: Right skewed distribution representing index values. Raw data values range from 0 to 20000.  

* Translation: Where is risk of tree dieoff during drought low?  

* Translation method and outcome: Raw data values translated to range from +1 to -1 representing more favorable to less favorable conditions, respectively. **** The proposition of more favorable is based on the objective of tree dieoff during drought being lower (negative linear slope). More favorable (translated to +1) and less favorable (translated to -1) are based on climate and vegetation regions (Table 5).
