Regeneration Harvest Sample Clauses

Regeneration Harvest. Due to location in the eastern Cascades forest ecosystem, the Applicants lands include areas with a high degree of landscape and tree species diversity, including patches of Oregon white oak and other deciduous species mixed within conifer forests being regeneration-harvested. These patches provide significant value to wildlife and spotted owl prey base. At the time of regeneration harvest, where they exist and to the extent practical and economically feasible during harvest activities, the Applicants’ foresters will prioritize these patches of valuable habitat for inclusion as wildlife reserve tree and snag creation areas (Section 4.1.11). Stands selected for regeneration harvest will generally be 50 years of age or older (averaging a stand age of 60 years). Stands are examined for health, species composition, and wood quality to match the existing market conditions. When the final selection is made, regardless of slope, the stand is placed on the annual harvest plan. Several harvest systems might be used during regeneration harvests depending on topography and soil conditions. Ground-based equipment may include logging shovels, skidders, crawlers, or forwarders. Normally on slopes less than 35%, felling is conducted with processing equipment. Due to potential soil compaction, skidders and crawlers are restricted to long reaches (i.e., greater than 800 feet), where other equipment would not be economical. On slopes greater than 35%, hand felling is the only means of felling and bucking, and cable systems are employed with landings positioned at either the top or bottom of the unit, or both. Cable yarding provides additional challenges in distribution of legacy trees for the future stand. Whereas ground-based equipment provides some limited opportunities for distribution of legacy trees within the unit, cable yarding is far more constrained. Legacy trees would generally be retained along edges, in fewer but larger patches, or triangular wedges at ends of cable runs. During regeneration harvest on slopes less than 35%, legacy trees may be clumped, distributed, or distributed in smaller clumps depending on logistics and economics. Where snags are retained, i.e., Types 3 and 4 wildlife reserve trees as defined in Washington Forest Practices (WAC 222-16-010) but also applied to the Applicants’ covered Oregon lands, there may be a small clump of live trees surrounding these snags for safety considerations. For snags without a lean, this patch would generally be...

Regeneration Harvest. Even-age regeneration harvests are not scheduled and may be conducted when revenue is required. However, even-age regeneration harvests are subject to an even-flow constraint intended to create and maintain an area-based balance of age classes and habitat types over time. There are approximately 1,781 acres of forest land designated for even-age management. Given a minimum harvest age of 60 years, an annual even-flow constraint limits harvest to approximately 30 acres per year (30 ≈ 1781 ∕ 60). The even- flow constraint will be applied over a five year period to allow market and management flexibility. Simply stated, even-age regeneration harvest of more than 150 acres, in any five-year period, is restricted. There are approximately 268 acres of forest land designated for uneven-age management in the southern portion of the LCT. The intention of this management approach is to regenerate and maintain forest stands with three or more cohorts by harvesting in small groups (≤ 1 acre). Uneven-age regeneration harvest will occur in 30-year cycles. At each harvest cycle, up to one third of the uneven-age management stands may be harvested in small groups (≤ 1 acre). Regeneration harvesting will not recur within groups until regenerated trees reach age 120 years.
