* Metric Name: Seed/spore dispersers Species Richness *  

* Tier: 2  

* Data Vintage: 04/2023  

* Unit Of Measure: Number of species  

* Represent element and pillar: Yes  

* Type and distribution of data: Left skewed distribution representing count data. Raw values range from 0 to 15 species. Maximum values varied among climate classes.  

* Translation: Where is seed and spore dispersing species richness high?  

* 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 supporting higher species richness of the functional group (positive linear slope). More favorable (translated to +1) and less favorable (translated to -1) based on climate regions (Table 7). Alternative approaches could use the theoretical maximum of all species in the functional group to define more favorable (+1), but that would assume that all species could cohabitate in a single location.
