date Source_Contribution: Used to delineate habitat type Process_Step: Process_Description: Six iceplant species were mapped (via GPS) over a period of 1.5 yrs at twenty-four select salt marsh locations in Southern California. Polygons represent presence of a particular species and percent cover was variable. Often the iceplants were growing amongst other plants and othertimes it completly dominated. Shapefiles were created for each individual species at each wetland location.

Attributes were then assigned to the database to designate species name, location, observer, mapping method, date species was mapped, habitat type, and acreage. Seperate habitat data developed by Eric Zahn was then incorporated into the existing data through a "union" process. Metadata was then created for the finalized dataset.
