Jepson eFlora: KeyBase Region Species List Update Logs

NOTE: The KeyBase taxon filters are based on Jepson eFlora author's assertions of taxon ranges. As we have discovered from comparing Consortium of California Herbaria (CCH) specimen records to eFlora authored ranges in the Yellow Flag project, there are many plant populations that occur outside the eFlora authored ranges.

The Jepson eFlora divides California into 35 ecologically distinct bioregions for the purpose of indicating where plant taxa grow. The smallest subdivision defined as a distinct bioregions, depends on how finely each region is ecologically divided. One bioregion, the Sonoran Desert, is at the finest scale at the region-level, and is not divided into subregions. The other nine regions are further divided into two or more subregions. Seven subregions are further divided into two or more districts. All regions are grouped into three main provinces, as shown in the maps above.

Each terminal taxon treatment in the Jepson eFlora indicates the treatments in which the taxon is asserted to occur. Using this information, a checklist for any subregion, region or province can be made (see the eFlora Tools page for a tool that does exactly that).
