The polygons mapped here by default are the Zones for CalVeg data. All the data of the original source data (http://www.fs.usda.gov/Internet/FSE_DOCUMENTS/stelprdb5362995.zip) are also provided in this upload.
Note that the North Caost has three subzones on the CalVeg data site, dtermined by the Ecoregion Sections.
This polygon layer consists of boundaries for the ecological tile units and CALVEG zone units currently being used to tile the EVEG (existing vegetation) dataset. Selected lines were added from the CalWater watershed layer where finer tile divisions were needed.Additionally, attributes from Ecological Units of California (Ecological Domain, Division, Province, Section and Subsection) have been incorporated into this layer.
