1 Kuiu Timber Sale Unit Card Unit Number: 32 Unit Acres: 66 Alternatives: Aerial 298_123, Land Use Net Timber Photo: 298_124 Designation: Timber Production Volume: TM-Compartment and Stand: Volume Strata Acres: Existing Stand Condition: Old-growth High Medium Low Silvicultural Prescription: Uneven-aged management, 5% BA retention, Single Tree Selection Logging Method/ Transportation: Helicopter / Use landing on existing NFS Road (6413) 66 Resource Concerns & Responses 1,39 MBF Fish Habitat/Watershed Concern: Streams 1, 4, and 7 are Class III, Channel Type HC5. Streams 2, 3, 5, and 6 are Class IV, Channel Type HC5. Response: Streams 1, 4, and 7: No programmed commercial timber harvest within the RMA, which is defined as the V-notch. Implement BMPs 12.6, 12.6a, 13.9, and Streams 2, 3, 5, and 6: Split yard away from Class IV streams whenever possible. Buck, limb, and top felled trees clear of streamcourses. Remove any slash deposited in streamcourse as a result of timber harvest activities. Implement BMPs 12.6, 12.6a, 13.9, and Soils Concern: Steep soils exist in patches in unit. Response: Helicopter harvest with full suspension. Wildlife/Biological Diversity Concern: Large amount of high Volstrata in unit. Less than one acre of high value deer habitat (HSI >.6), 3 acres of medium value deer habitat (HSI.4 to.5) and 66 acres of high value marten habitat (HSI >.89) are within the unit. Response: 5% BA retention would help maintain old-growth characteristics and values and retain high value marten habitat. Harvest would not isolate habitat and no corridors would be removed. No resource concerns for: Scenery, Heritage, Vegetation, Wetlands, Karst 54 Appendix B Kuiu Timber Sale FEIS

Response: Soils Concern: Response: 1,157 MBF Streams 1, 2, 3, and 4: No programmed commercial timber harvest within the RMA, which is defined as the V-notch. Implement BMPs 12.6, 12.6a, 13.9, and Unit initially had 1 acres of extreme hazard soils (MMI-4). Extreme hazard soils (MMI-4) were deleted from unit boundary. No further soil concerns. Wildlife/Biological Diversity Concern: Large amount of high Volstrata in unit. 22 acres of important deer habitat (HSI >.6) and 58 acres of high value marten habitat (HSI >.89) within the unit. Response: 5% BA retention would mitigate harvest by retaining old-growth characteristics and values and retain marten and deer habitat. Harvest would not isolate habitat and no corridors would be removed. No resource concerns for: Scenery, Heritage, Vegetation, Karst, Wetlands 56 Appendix B Kuiu Timber Sale FEIS

Stream 2 is Class IV, Channel Type HC5. Stream 3 is Class III, Channel Type HC6. Response: Streams 1 and 3: No programmed commercial timber harvest within the RMA, which is defined as the V-notch. Implement BMPs 12.6, 12.6a, 13.9, and Stream 2: Split yard away from Class IV streams whenever possible. Buck, limb, and top felled trees clear of streamcourses. Remove any slash deposited in streamcourse as a result of timber harvest activities. Implement BMPs 12.6, 12.6a, 13.9, and Soils Concern: Unit initially had 12.5 acres extreme hazard soils (MMI-4) that had evidence of windthrow. Response: Unit boundary was designed to avoid all extreme hazard soils (MMI-4). No further soil concerns. Wildlife/Biological Diversity Concern: Large amount of high Volstrata in unit. 5 acres of high value (HSI >.6) deer habitat and 24 acres of high value marten (HSI >.89) habitat are within unit. Response: 5% BA retention would mitigate harvest by retaining old-growth characteristics and values and retain marten and deer habitat. Harvest would not isolate habitat and no corridors would be removed. No resource concerns for: Scenery, Heritage, Vegetation, Wetlands, Karst 58 Appendix B Kuiu Timber Sale FEIS

Implement BMPs 12.6, 12.6a, 13.9, and Stream 2: No programmed commercial timber harvest in the RMA, which is defined as the greatest of the floodplain, riparian vegetation or soils, riparian associated wetland fens, or 12 feet. Implement BMPs 12.6, 12.6a, 13.9, and Location makes this stand susceptible to windthrow. Streams 1 and 2: For Alts 3, 4 and 5 the riparian buffer will be protected by feathering the edge for a distance of 5 horizontal feet where trees less than 16 inches DBH and those trees that cannot be felled away from the buffer will be retained. Wildlife/Biological Diversity Concern: Large amount of high and medium Volstrata in unit. 8 acres of high value deer habitat (HSI >.6) and 8 acres of high value marten habitat (HSI >.89) are within the unit. Response: Harvest would not isolate habitat and no corridors would be removed. No resource concerns for: Soils, Wetlands, Karst, Scenery, Heritage, Vegetation 6 Appendix B Kuiu Timber Sale FEIS
