CALIFORNIA NATIVE PLANT SOCIETY RARE PLANT RANKING 1A = Species presumed extinct. 1B = Species rare, threatened, or endangered in California and elsewhere. These species are eligible for state listing. 2A = Plants presumed extirpated in California, but more common elsewhere. 2B = Species rare, threatened, or endangered in California but more common elsewhere. These species are eligible for state listing. 3 = Species for which more information is needed. Distribution, endangerment, and/or taxonomic information is needed. 4 = A watch list of species of limited distribution. These species need to be monitored for changes in the status of their populations. .1 = Species seriously threatened in California (over 80% of occurrences threatened; high degree and immediacy of threat). .2 = Species fairly threatened in California (20-80% occurrences threatened; moderate degree and immediacy of threat). .3 = Species not very threatened in California (<20% of occurrences threatened; low degree and immediacy of threat or no current threats known). CBR = Considered but rejected
