Whenever it appears to the Governor that by reason of extreme drought or other hazardous conditions there is danger of forest fires, he may proclaim that any or all sections of woodland and brush land in the state shall be closed, for such time as he may designate, to all persons except the owners or tenants of such woodlands and their agents and employees, and during such period of closure no fire shall be kindled in the open air. As soon as the woodland is deemed free from the danger of fire, the Governor may revoke his proclamation. Any person who enters upon forest or brush land, except as provided herein, or who kindles or causes to be kindled a fire in the open air, during the period covered by the Governor’s proclamation, shall be fined not less than five dollars nor more than one hundred dollars or imprisoned not more than six months or be both fined and imprisoned.
