It is hereby declared to be in the interest of the welfare of the people of this state that the need for wood, lumber, poles, piling, wood pulp and other forest products, augmented by the growth of population, requires all forest lands to be kept in a fully productive condition. It is further declared that there are within the state more than two million acres of burned and cutover lands not now contributing adequately to the growth of forest crops nor to the economy of the state. It is further declared to be in the interest of the people of California that the state determine feasible means and methods for reforesting nonproducing forest lands to the end that all forest lands will be eventually brought up to their maximum growth capacity.
