USFWS again fails to list California endangered plants

The U.S. Fish & Wildlife Service published a revised list of Candidate Plants under the Federal Endangered Species Act on November 22, 2013.  Six California endemic plants remain formal Candidates (including their number of documented occurrences):

               Family                  Taxon                                                 Occurrences
               Brassicaceae         Rorippa subumbellata                                  29          
                                         Streptanthus bracteatus                                 8
               Liliaceae               Calochortus persistens                               5
               Nyctaginaceae       Abronia alpina                                             1
               Pinaceae               Pinus albicaulis                                       >10,000?

None of these six are particularly endangered: Pinus albicaulis shows no direct evidence of decline in the Sierra (unlike in the northern Rocky Mountains, suggesting genetics).  Rorippa subumbellata, endemic to the beaches of Lake Tahoe, now trampled and stranded, is uncommon but not critical.  Streptanthus bracteatus is a rare serpentine endemic, but has not declined in recent times.  Calochortus persistens is very rare, but is the subject of active USFS management, recently formalized in a signed directive.  Perhaps of the 6 candidates, only Abronia alpina might be considered threatened.

The USFWS revised Candidate List also removed two California plants from Candidate status: Hazardia orcuttii (Asteraceae) with ca. 15 extant occurrences, and Phacelia stellaris (Hydrophyllaceae) also with about 15 extant occurrences.

What the U.S. Fish & Wildlife Service failed to do in revision of the list of Candidate Plants is to in any way advance to candidacy the nearly 100 California endemic plants that are biologically endangered or threatened BUT WHICH ENJOY NO LISTING STATUS.

The list below are those CA endemics with three or fewer known occurrences, and which are not State Listed.  Some of these are not now in danger of extinction, as they occur in remote areas, and hence ought to be listed as Threatened (N is the number of extant occurrences).  

California harbors more endangered plants than the remainder of the coterminous United States combined (absent Florida and Hawaii, and excluding tropical Pacific protectorates).   

USFWS - do triage, get with the program, list these plants.
