California Code, Food and Agricultural Code (Formerly Agricultural Code) - FAC § 80102

(a) Each permit authorizing the harvesting, transporting, or possessing of native plants, except trees cut or removed for wood as provided in Section 80103, shall be accompanied by a sufficient number of tags and seals. The permittee or his or her agent shall attach the tags and seals to the native plants at the time of harvesting and before transporting in such manner as prescribed by the commissioner of the county in which the native plants are located. After any native plant has been legally harvested and tagged or sealed as provided in this division, it is unlawful to remove the tag or seal until the plant has been transplanted into its ultimate site for landscaping or decoration. The tag or seal may be removed from the plant only by the commissioner or the ultimate owner of the plant, who shall retain the tag or seal as proof of ownership.

(b) No permit or tag or seal is transferable by the permittee or his or her agent, nor shall it be used by anyone except that person to whom the permit or tag or seal was issued, and no refunds shall be made for the purchase thereof.

(c) Every permittee is responsible for the acts of any other person or persons acting under any authority, express or implied, of the permittee.
