4597.2. A working forest management plan may be submitted to the department in writing by a person who intends to become a working forest landowner with the long-term objective of an uneven aged timber stand and sustained yield through the implementation of a working forest management plan. The management plan shall be prepared by a registered professional forester. It shall be public record and shall include all of the following information:
(a) The name and address of the timberland owner.
(b) A description of the land on which the plan is proposed to be implemented, including a United States Geological Survey quadrangle map or equivalent indicating the location of all streams, the location of all proposed and existing logging truck roads, and the boundaries of all site I classification timberlands to be stocked in accordance with subdivision (b) of Section 4561 and any other site classifications if the board establishes specific minimum stocking standards for other site classifications.
(c) A description by the registered professional forester of the inventory design and timber stand stratification criteria that demonstrates that the inventory supporting the growth and yield calculations used to determine long-term sustained yield for the working forest management plans meets the following minimum standards:
(1) For major stand or strata, the inventory estimate shall be within 15 percent of the mean at one standard error.
(2) For stand or strata that make up greater than 10 percent and less than 25 percent of the working forest management plan area, the estimate shall be no greater than 25 percent of the mean at one standard error.
(3) Inventory estimates and growth and yield shall be projected for the purposes of determining long-term sustained yield and volumes available for harvest by stand or strata and aggregated for the area covered by the working forest management plan to develop the long-term sustained yield estimate. Long-term sustained yield estimates shall reasonably reflect constraints applicable to the working forest timberlands on forest management activities.
(d) All necessary information shall demonstrate compliance with Article 12 (commencing with Section 923) of Subchapter 4 of, Article 11 (commencing with Section 943) of Subchapter 5 of, and Article 12 (commencing with Section 963) of Subchapter 6 of, Division 1.5 of Title 14 of the California Code of Regulations.
(e) Special provisions to protect unique areas, if any, within the boundaries of the proposed working forest management plan.
(f) A description of the property and planned activities including acres and projected growth, existing stand types, major stand types or strata, its current projected growth by strata, silvicultural applications to be applied to strata to achieve long-term sustained yield, projected timber volumes and tree sizes to be available for harvest, and projected frequencies of harvest.
(g) (1) A description of late succession forest stands in the plan area and how the total acreage of this type of habitat will be maintained across the plan area under a constraint of no net loss. Nothing in this requirement shall be interpreted to preclude active management on any given acre of an approved plan if the management is conducted in a manner that maintains or enhances the overall acreage of late succession forest stands that existed in the plan area upon initial plan approval. An exception to the no net loss constraint may be granted in the event of a catastrophic loss due to emergency factors such as wildfire, insect, and disease activity. The description shall include the following:
(A) Retention measures for existing biological legacies such as snags, trees with cavities or basal hollows, and down logs, and address how those legacies shall be managed over time appropriate with the forest type, climate, and landowner’s forest fire fuels and wildlife management objectives.
(B) Hardwood tree species and how they will be managed over time.
(2) Late succession forest stand types or strata shall be mapped.
(3) Notwithstanding the definition of late succession forest stands in Section 895.1 of Title 14 of the California Code of Regulations, and for the sole purpose of this article, “late succession forest stands” means stands of dominant and predominant trees that meet the criteria of the California Wildlife Habitat Relationships System class 5D, 5M, or 6 with an open, moderate, or dense canopy closure classification, often with multiple canopy layers, and are at least 10 acres in size. Functional characteristics of late succession forest stands include large decadent trees, snags, and large down logs.
(h) Disclosure of state or federally listed threatened, candidate, endangered, or rare plant or animal species located within the biological assessment area, their status and habitats, take avoidance methodologies, enforceable protection measures for species and habitats, and how forest management will maintain these over time.
(i) (1) A description of the following for each management unit:
(A) Acres by stand or strata and estimated growth and yield for each planned harvest entry covering the period of time the long-term sustained yield plan establishes as necessary to meet growth and yield objectives. The growth and yield estimates may be based on weighted average of yield for the stand types or strata within the area included in the management unit.
(B) Yarding methods to be used.
(C) Management units shall be mapped.
(2) (A) For long-term sustained yield projections, pursuant to subdivision (c), that project a reduction in quadratic mean diameter of trees greater than 12 inches in diameter or a reduced level of inventory for a major stand type or for a stand or strata that make up greater than 10 percent and less than 25 percent of the working forest management plan area, an assessment shall be included that does all of the following:
(i) Addresses candidate, threatened, endangered, and sensitive species, and other fish and wildlife species that timber operations could adversely impact by potential changes to habitat.
(ii) Addresses species habitat needs utilizing the “WHR system” described in “A Guide to Wildlife Habitats in California,” California Department of Fish and Wildlife, 1988, or comparable typing system.
(iii) Addresses constraints to timber management, the impact of the availability and distribution of habitats on the ownership and within the cumulative impacts assessment area identified in the plan in relation to the harvest schedule, and the impacts of the planned management activities utilizing the existing habitat as the baseline for comparison.
(iv) Discusses and includes feasible measures planned to avoid or mitigate potentially significant adverse impacts on fish or wildlife, which can include, but is not limited to, recruitment or retention of large down logs greater than 16 inches in diameter and 20 feet in length, retention of trees with structural features such as basal hollows, cavities, large limbs, or broken tops, retention of hardwoods, and retention or recruitment of snags greater than 24 inches in diameter and 16 feet in height.
(j) A certification by the registered professional forester preparing the plan that the forester or a designee has personally inspected the plan area.
(k) A certification by the registered professional forester preparing the plan that the forester or a designee has clearly explained to the working forest landowner that the plan is a long-term commitment that may require ongoing investments, including inventory sampling and road maintenance, for the purpose of managing the plan.
(l) Any other information the board requires by regulation to meet its rules and the standards of this chapter.
