Cal. Public Resources Code § 4631

It is hereby declared to be in the interest of the welfare of the people of this state and their industries and other activities involving the use of wood, lumber, poles, piling, and other forest products, that desirable cutover forest lands, including those having young and old timber growth, be made fully productive and that the holding and reforestation of such lands is a necessary measure predicated on waning supplies of original old growth timber. It is further declared to be the policy of the state to acquire by purchase, exchange, lease, or grant all of the following: (a) Such cutover lands, the reforestation of which is not assured under private ownership, to reforest such lands during periods of unemployment and at other times. (b) Liquidating forest lands primarily suitable for timber production which may be acquired under precutting agreements. (c) Demonstration forests of 2,000 acres or less adapted to furnish local needs of investigation, demonstration, and education in those timber counties where the ownership pattern is such that management of small areas is an important problem. (d) One area, not to exceed approximately 40,000 acres, in each of the following forest districts, Coast Range Pine and Fir District, North Sierra Pine District and the South Sierra Pine District, for the purpose of demonstration of economical forest management. These areas shall not include virgin timber except that which is incidental to areas previously harvested.
