* Metric Name: Wetland Type Composition  

* Tier: 1  

* Data Vintage: 06/2018  

* Unit Of Measure: Binary, 0 (Presence), 1 (Absence)  

* Represent element and pillar: No  

* Type and distribution of data: Binary distribution representing presences/absences. Raw values range from 1 to 1.  

* Translation: Where is wetland type composition the highest?  

* 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 high wetland type composition (positive linear slope). More favorable (translated to +1) set at 1, and less favorable (translated to -1) set at > 0\.

* Metric Definition and Relevance: 

  * _Wetlands_ \- This data set represents the extent, approximate location, and type of wetlands and deepwater habitats in the ACCEL boundary for the Southern California. These data delineate the areal extent of wetlands and surface waters as defined by Cowardin et al. (1979).
  *  _Riparian_ \- This data set represents the extent, approximate location, and type of riparian habitats in the ACCEL boundary extent. These data delineate the areal extent of riparian habitats as defined by A System for Mapping Riparian Areas in the United States (USFWS, 2009)
