At some point in mid-nineties there was a desprate need to spatially reconcile two competing databases of plant diversity in California. Between the CalFlora database using the "sub-county" designation of Lum and colleagues, and the Jepson demarcation by ecoregions, the "CalJep" geodatabase was born. It is fully described in Viers et al. 2006. The geodatabase has been used in about 30 different studies (as of 2016), but remains in version 1 status. Changes in taxonomy and distribution should be investigated. Otherwise, the file can be downloaded here: CalJepGeoV1 [240 MB] formatted as ESRI Personal Geodatabase (.mdb).
