Special-Status Plants with Potential to Occur in the Project Footprint Page 4 of 4 Status Explanations Federal E = listed as endangered under the federal Endangered Species Act T = listed as threatened under the federal Endangered Species Act – = no listing State E = listed as endangered under the California Endangered Species Act T = listed as threatened under the California Endangered Species Act R = listed as rare under the California Native Plant Protection Act. This category is no longer used for newly listed plants, but some plants previously listed as rare retain this designation – = no listing. California Native Plant Society 1A = List 1A species: plants presumed extinct in California and elsewhere 1B = List 1B species: rare, threatened, or endangered in California and elsewhere 2 = List 2 species: rare, threatened, or endangered in California but more common elsewhere 3 = List 3 species: plants about which more information is needed to determine their status 4 = List 4 species: plants of limited distribution 0.1 = seriously endangered in California 0.2 = fairly endangered in California 0.3 = not very endangered in California b Likelihood of Occurrence High: Known occurrence of plant within 2 miles of the project vicinity from CNDDB or other documents, or presence of suitable habitat conditions and suitable microhabitat conditions Moderate: Known occurrence of plant within 2 miles of the project vicinity from CNDDB or other documents; suitable habitat is present but suitable microhabitat conditions are not Low: Plant not known to occur within 2 miles of the project vicinity from CNDDB or other documents, or habitat conditions are of poor quality, or species presumed extirpated from
