Current through Register 2024 Notice Reg. No. 28, July 12, 2024
(a) Consistent with the protection of soil,
					 water, air, fish and wildlife resources a SYP shall clearly demonstrate how the
					 submitter will achieve maximum sustained production of high quality timber
					 products While Giving Consideration to regional economic vitality and
					 employment at planned harvest levels during the planning horizon. The average
					 annual projected harvest over any rolling 10-year period, or over appropriately
					 longer time periods for ownerships which Project harvesting at intervals less
					 frequently than once every 10 years, shall not exceed the long-term Sustained
					 Yield estimate for a SYP submitter's ownership.
(b) Where a SYP is based upon data on file
					 with the Director, such data shall be updated every 10 years. Proprietary
					 information shall be treated consistent with PRC §
											21160.
(c) Each sustained timber production
					 assessment shall include:
(1) A summary table
					 of Wildlife Habitat Relationships compositions and stand structure types (WHR),
					 or comparable stand structure types within forest vegetation types with their
					 respective acreage. For an ownership's specific stand structure types, the RPF
					 shall provide a written description of the stand structure and characteristics
					 which define each type, and comparisons of those types to WHR typing. The WHR
					 system, which is herein incorporated by reference, and its uses described in
					 "Guide to the California Wildlife Habitat Relationships System," California
					 Department of Fish and Game, March 1988.
(2) An estimate of the long-term Sustained
					 Yield of the ownership stated in terms of board feet per year or cubic feet per
					 year, or other reasonable measurement consistent with products chosen by the
					 owner, and a description of how the estimate was reached. For ownerships that
					 have not attained long-term Sustained Yield, the SYP shall estimate and justify
					 the transition period necessary to achieve long-term Sustained Yield.
(3) A projection of growth and harvest for
					 each WHR type or comparable stand structure type within forest vegetation type
					 over each 10 year period in the planning horizon, and a description in
					 narrative form of the accuracy and methodology used to estimate
					 growth.
(4) A discussion of the
					 accuracy of the inventory data for the management unit and/or ownership.
					 Inventory data, models and growth and harvest projections utilized for harvest
					 scheduling projections shall be available for confidential audits by reviewing
					 agencies along with the basis for such data, including but not limited to the
					 cruise design and sample plot data and statistical validity of such estimates.
					 The SYP shall describe how the submitter will, over time, make reasonable
					 progress to improve inventory estimates for the major WHR or vegetation types,
					 with a goal of achieving standard errors that are no greater than 15% of their
					 respective inventory estimates within the effective period of the SYP. The
					 major WHR types include all tree-dominated habitats in size classes 4, 5, and 6
					 with Canopy closure classes of S,P,M, and D.
(5) A description of the prescriptions
					 applied to each stand type projected. A narrative discussion of the methods
					 used to Project inventory, growth and harvest and WHR type or comparable stand
					 structures type.
