This THP is about 7 miles east of Scotia, CA just off Highway 36 near Grizzly Creek Redwoods State Park.  The THP area drains into the Van Duzen River which is listed as impaired for sediment and temperature. Humboldt Redwood Company is planning a tractor, cable and helicopter logging operation in redwood, Douglas fir and grand fir forests at an elevation of 300 to 1,550 feet.  The THP area has over 70 active and dormant landslide terrain features including debris slides, debris side slopes, disrupted ground, earth flows, rockslides and inner gorges.  There are some misc road failure sites including cutbank failures and fill failures.  Humboldt Redwood Company is planning to use ground based equipment in areas designated for cable logging, and to use helicopters for logging which often are used to remove large trees off steep and unstable slopes.  There are 16 road drainage sites planned for work including rocking, dip construction, ditch cleaning, culvert repair/replacement and temporary bridge construction.  A sharp shinned hawk nest was located just outside of unit 1, and there is willow flycatcher habitat within .25 mi of unit 1. More information is available on the THP Tracking Center website.
