NOTES: Appendix A: Special Status Plant Species with Potential to Occur on the Project Site. 17 1 Excerpted from CDFW CNDDB (2022) 2 Excerpted from CNPS (2022) 3 The potential for occurrence is based on occurrences recorded in the CDFW CNDDB (2022) and CNPS (2022), knowledge of species requirements, and site inspections during 2022 field survey 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)
