STATUS KEY:
Federal
FE: Federally-listed Endangered
FT: Federally-listed Threatened
State
SE: California-listed Endangered
ST: California-listed Threatened
California Native Plant Society (CNPS): CNPS has developed five categories of rarity known as the California Rare Plant Ranking (CRPR). CRPR designations are
defined as follows:
1A: Presumed extinct in California
1B: Plants listed as rare, threatened, or endangered in California and elsewhere
2B: Plants rare, threatened, or endangered in California, but more common elsewhere
3: Plants about which we need more information
4: Species of limited distribution in California, but whose existence does not appear to be susceptible to threat
CNPS also adds a decimal threat rank to the List rank to parallel that used by the CNDDB. CNPS rank designations therefore appear as: 1B.1, 1B.2, etc. Threat
code extensions are defined as follows:
.1 – Seriously endangered in California (over 80% of occurrences threatened / high degree of immediacy of threat)
.2 – Fairly endangered in California (20-80% occurrences threatened)
.3 – Not very endangered in California (<20% of occurrences threatened or no current threats known)
