This THP is about 14 miles NW of Lakehead, CA and about 4 miles west of Interstate 5 near the Sacramento Canyon at an elevation of 4,640 to 6,380 feet. Sierra Pacific Industries is planning a tractor based clearcut logging operation on steep and unstable slopes in white fir, red fir, Port Orford cedar (locally rare), western white pine, Jeffrey pine, ponderosa pine, sugar pine, Douglas fir and incense cedar forests. There is an active unstable area (roadside fill failure) along the east side of Slate Creek, and hummocky landscape terrain in sections 11 and 13. This THP is within a mile of the popular trail system that links Tamarack and Twin Lakes and has regionally uncommon Port Orford Cedar trees which can be killed by the spread of Port Orford Cedar root rot through logging. SPI is planning to use ground based equipment on steep slopes over 65% grade in unit 13C, and use ground based equipment on slopes over 50% grade with a high erosion hazard in unit 11C. 20 road drainage sites are planned for work including rocking, dip construction, culvert repair/replacement and restoration of washed out crossings. A Pacific tailed frog was reported to be 2,460 feet from unit 13E in section 24. 12 sensitive plant species were reported including: Klamath manazanita in units 7A, 7B, 7E and 13E, Scalloped moonwart in unit 7E, Mingan moonwart in unit 7E, Clustered lady’s slipper in unit 13B, Picher plant in units 7C and 7E, Congdon’s buckwheat in units 7A, 7E, 11B, 11C, 11D, 15A and 15B, Scott Mountain phacelia in units 7A, 7B, 7C, 15A and 15B, Redwood lily in unit 7E, Englemann’s lomatium in units 7A, 15A and 15B, Cascade grass of parnassus in unit 7E, Threadleaf beardtongue in unit 7A and Yellow triplet lily in unit 15A.
