This THP is about 5 miles NE of Carlotta, CA and Highway 36 at an elevation of 480 to 2,150 feet. Humboldt Redwood Company is planning a tractor and cable logging operation on steep and unstable slopes in redwood, Douglas fir and grand fir forests. The THP area flows into the Van Duzen River which is listed as an impaired watershed for sediment and temperature. There are 46 landslide terrain sites including earth flows, debris flows, gullies, disrupted ground, debris slides, rock slides, steep inner gorges, and multiple road failure sites including deposits on the road surface, bank sloughing, cracking, fill failures and cut bank failures. Logging is proposed inside large tree marbled murrelet stands 543D & 570D in unit 4, and marbled murrelet stands 212B and 220B in unit 2. Humboldt Redwood Company is planning to use ground based equipment in areas designated for cable logging operations, and use ground based equipment on skid trails, on existing roads and to construct roads in unstable areas at 24 locations. They also are planning to use ground based equipment on a landing within a watercourse area in unit 5, and on a landing and on 3 segments of skid trails within a watercourse area in unit 7. 91 road drainage sites are planned for work including rocking, dip construction, ditch cleaning, culvert repair/replacement and restoration of washed out crossings. There are over a dozen northern spotted owl nesting territories within 1.3 miles of the THP area.
