<br />. . . <br /> <br />0029J1 <br /> <br />Maximum PNV Including Assigned Values Benchmark <br /> <br />(219.12(e}(1}(iii}(B) <br />(FEIS Benchmark Nos. 3) <br />(FORPLAN Run No.2) <br /> <br />Purpose: This benchmark defines the maximum net monetary value of market <br />resources (timber, developed recreation, and livestock outputs) and nonmarket <br />resources (dispersed recreation, wilderness, wildlife and fish, and water <br />outputs). It determines the most efficient mixture of market and non-market <br />resource uses on the Forest and the most efficient production schedule for <br />these resources. <br /> <br />This benchmark includes the basic provisions necessary to comply with current <br />legal requirements and policy guidelines. It serves, therefore, as the basic <br />benchmark with which other benchmark and land management alternatives are to be <br />compared. It provides the output levels and effects associated with maximum <br />economic efficiency within the context of the aforementioned legal limits and <br />policies. <br /> <br />FORPLAN Objective function: Maximize PNV for fifteen decades. <br />Constraints: <br /> <br />~ <br /> <br />-All minimum management requirements (MHR's) for soil, water, fish, and <br />wildlife must be met. <br /> <br />-Timber harvest is scheduled only on lands classified as tentatively <br />suitable for timber production. <br /> <br />-Timber harvest can equal but not exceed the long-term sustained yield <br />capacity (LTSY). <br /> <br />-Timber harvest levels can increase from decade to decade but not decline. <br /> <br />-Sufficient timber inventory must remain at the end of 150 years to sustain <br />timber harvest at the LTSY level. <br /> <br />-Regeneration cuts cannot be scheduled until stands have reached 95~ of <br />culmination of mean annual increment. <br /> <br />-Regeneration harvests are dispersed to meet Regional guidelines for size <br />and separation of harvest units. <br /> <br />Si nificant features and results: The PNV over the 150-year modeling period is <br />2.3 billion dollars. There are 864,904 acres identified as suitable for <br />timber production, with a long term sustained yield level of 23.724 MMCF (106.8 <br />MMBF) per year. During the first and second decade, the annual offer level is <br />13.258 MMCF (59.0 MMBF). In the sixth decade, the level increases to long run <br />sustained yield for the rest of the modeling period. Some aspen is <br />commercially harvested in the second decade. <br /> <br />34 <br />
