The killing or possession of California rare, threatened or endangered plant species (PDF) is prohibited by California law, however CDFW may issue permits authorizing the "take" or possession of these species under certain circumstances, such as for scientific, educational or management purposes or if the take is incidental to otherwise lawful activities and certain conditions are met. CDFW issues most of these permits to individuals to identify, document and voucher listed plant species (PDF), typically during botanical surveys, and may also issue permits to individuals or organizations for other scientific, educational or management purposes, most typically research or recovery actions for state-listed plant species. CDFW also partners with several botanic gardens and other institutions for ex-situ or “off-site” conservation of rare, threatened, and endangered plant species, and several California herbaria have collections of rare, threatened, and endangered plant specimens. See a list of facilities that have active agreements with CDFW.
- Voucher Collection Permit. A voucher collection permit is required to collect rare, threatened and endangered plant species for identification purposes during field surveys, or to collect voucher specimens to document a newly-discovered or previously unvouchered occurrence of a listed plant. There is no charge to apply for a voucher collection permit. Anyone who collects scientific plant specimens of state-listed species, or who may encounter a state-listed species that needs to be identified during field surveys should have a plant voucher collection permit.
- Scientific, Educational, or Management Permit. Other scientific, educational or management activities on state-listed plant species may be authorized with a scientific, educational or management permit. These permits are required for scientific, educational or management activities that will result in “take”, possession, import or export of state-listed plant species such as research, seed banking, reintroduction efforts, habitat restoration and other activities. Applicants should submit a proposal to CDFW that contains the information identified in the document below. There is no charge to apply for a scientific, educational, or management permit.
- Incidental Take Permit. In addition to the permits discussed above, CDFW may also authorize the incidental take or possession of certain state-listed species in conjunction with otherwise lawful activities via Incidental Take Permits, Natural Community Conservation Plans or other mechanisms.
