If a fire patrol for the prevention and suppression of forest fires is maintained by owners of land or by any organization, the director may designate each patrolman as a voluntary firewarden and, for the protection of lands patrolled by him or adjacent to such lands, may give him all the rights and powers of a voluntary firewarden. Voluntary firewardens shall be paid by such owners or organizations or as provided for by Section 4151. Such firewardens do not have authority to obligate the state for the payment of any money, unless specifically so authorized by the director.
