This THP is about 28 miles north of Redding, CA in the Sacramento Canyon and about 8 miles north of the town of Lakehead and Shasta Lake at an elevation of 1,600 to 5,200 feet. Sierra Pacific Industries is planning a mostly clearcut tractor and cable logging operation on steep and unstable slopes in white fir, Douglas fir, ponderosa pine, sugar pine, incense cedar and port orford cedar forests. Unit 9A has an unstable area below the last existing skid trail outside of the unit, units 3A and 9C have unstable areas associated with watercourse erosion, and unit 3D has an existing road cut bank failure and watercourse erosion. Sections 9 and 33 are adjacent to the Slate Creek roadless area. SPI is planning to use ground based equipment in areas designated for cable logging inside units 3C, 3D, 9B, 21B, 27A, 27D, 35E and 35F, and re-use 2 existing skid road crossings inside watercourse area within units 35A and 35D. They also want to build temporary roads under 500 feet without flagging and use temporary roads and landings during the winter period. Tractor units 3A, 9A, 27E and 35D have areas in which slopes exceed 50% that lead without flattening before reaching a watercourse. 13 road drainage sites are planned for work including rocking, dip construction, ditch cleaning and culvert repair/replacement. An osprey nest is located on the east side of the Sacramento River near I-5 (section 15), pacific fisher sightings were reported in sections 2, 13, 16 and 17, and a bald eagle nest is located 1.25 miles from the THP area in the Boulder Creek Watershed (section 16).
Several sightings of western pond turtles were reported in the Boulder Creek Watershed over a mile from the THP area in sections 18 and 24, and multiple occurrences of tailed frogs were reported in the Boulder Creek, Shotgun and Little Slate watersheds in sections 14, 24, 27 and 28. Foothill yellow legged frogs were reported in sections 6, 9, 14, 18, 21, 24, 33, 34, and 35.
