Category 1 includes species for which USFWS has on file enough <br /> substantial information on biological vulnerability and threat to support proposals to list them. <br /> 4T <br /> U_- C2 = Category 2 candidate for federal listing. Category 2 includes species for which USFWS has some <br /> biological information indicating that listing may be appropriate but for which further biological research <br />�'. and field study are usually needed to clarify the most appropriate status. Category 2 species are not i <br /> L necessarily less rare,threatened, or endangered than Category 1 species or listed species; the distinction <br /> relates to the amount of data available and is therefore administrative, not biological. <br /> California Native Plant Society (Smith and Berg 1988) <br /> l—' la = List la species: presumed extinct in California. <br /> lb = List 1b species: rare, threatened, or endangered in California and elsewhere. <br /> I <br /> 3 = List 3 species: plants about which more information is needed to determine their status. <br /> -- = no listing. <br />
