This THP is about 2.7 miles SE of Dorrington, CA and Highway 4 by Calaveras Big Trees State Park at an elevation of 4,550 to 5,570 feet.  Sierra Pacific Industries is planning a mostly clearcut tractor and cable logging operation on steep and unstable slopes in ponderosa pine, sugar pine, white fir, Douglas fir and incense cedar forests.  There are 3 landslide terrain sites in the THP area including; an unstable area adjacent to unit 1194, an unstable area within unit 2471, and an unstable area adjacent to a haul road.  Six acres of Special Treatment Area (STA) have been designated adjacent to California Big Trees State Park to hide the visual impacts of clearcutting (combination selection and fuel break prescription).  Sierra Pacific Industries is planning to use and construct roads, landings and crossings during the winter period, use ground based equipment on slopes between 50% and 65% with a moderate erosion hazard, use 2 existing skid trails inside a class III (intermittent) watercourse areas, and use a portion of an existing landing inside a class I (year round) watercourse area.  They also are planning to construct segments of steep temporary road exceeding 15% to 20% grade in unit 2967, construct segments of steep temporary road exceeding 15% to 20% grade in unit 1600 and 1607, and construct segments of steep temporary road exceeding 15% to 20% grade in unit 1637.  55 road drainage sites are planned for work including rocking, dip construction, ditch cleaning, culvert repair/replacement and restoration of washed out crossings.  In 1999, a northern goshawk nest was reported within .66 miles of the nearest unit (2521) in section 15. Threebract onion was found along a road adjacent to unit 2471, cut leaved monkey flower was found in unit 1515, Coleman’s rein orchid was found in units 2619, 2630, 3018, 2967, 1637, 1463 and 2521, and Rocky Mountain chickweed was found in or adjacent to units 1634, 1637, 1463 and 2521.  There are 10 CA spotted owl territories within 1.3 miles of the THP area.
