Cal. Const. art. XIII, § 3
The following are exempt from property taxation:
(j) Immature forest trees planted on lands not previously bearing merchantable timber or planted or of natural growth on lands from which the merchantable original growth timber stand to the extent of 70 percent of all trees over 16 inches in diameter has been removed. Forest trees or timber shall be considered mature at such time after 40 years from the time of planting or removal of the original timber when so declared by a majority vote of a board consisting of a representative from the State Board of Forestry, a representative from the State Board of Equalization, and the assessor of the county in which the trees are located.
The Legislature may supersede the foregoing provisions with an alternative system or systems of taxing or exempting forest trees or timber, including a taxation system not based on property valuation. Any alternative system or systems shall provide for exemption of unharvested immature trees, shall encourage the continued use of timberlands for the production of trees for timber products, and shall provide for restricting the use of timberland to the production of timber products and compatible uses with provisions for taxation of timberland based on the restrictions. Nothing in this paragraph shall be construed to exclude timberland from the provisions of Section 8 of this article.

The Legislature may increase this exemption and may deny it if the owner received state or local aid to pay taxes either in whole or in part, and either directly or indirectly, on the dwelling.
No increase in this exemption above the amount of $7,000 shall be effective for any fiscal year unless the Legislature increases the rate of state taxes in an amount sufficient to provide the subventions required by Section 25.
If the Legislature increases the homeowners’ property tax exemption, it shall provide increases in benefits to qualified renters, as defined by law, comparable to the average increase in benefits to homeowners, as calculated by the Legislature.
