This THP is about 7 miles east of Arnold, CA, 4 miles SE of Dorrington, CA along the SE boundary of Calaveras Big Trees State Park (5 units are adjacent) at an elevation of 4,500 to 5,600 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. The THP area flows into the North Fork of the Stanislaus River. Multiple landslide terrain sites exist in the THP area including; unstable areas inside units FB2 and 1641, and unstable areas adjacent to units 1456, 1632 and 2309. Sierra Pacific Industries is planning to use ground based equipment on slopes between 50% and 65% with a moderate erosion hazard, and construct a 160 foot segment of steep road exceeding 18% grade to access units 2475 and FB2.  Five road drainage sites are planned for work including rocking, dip construction, ditch cleaning, culvert repair/replacement and road bed construction.  2,811 feet of seasonal roads are proposed for construction, and 3,780 feet of seasonal roads are proposed for re-construction. Three northern goshawk nest sites exist within .35 to 1 mile from the THP area in sections 4, 15 and 35. Foothill yellow legged frogs were reported 2 miles SW of the THP area.  In 2019, a Sierra Nevada yellow legged frog was reported .7 miles SW of the nearest THP unit in section 24, and also 1.3 miles west of the nearest THP unit in section 13. There are 12 CA spotted owl territories within 1.3 miles of the THP area in sections 5, 14, 15, 22, 23, 26, 29, 33, 34, and 35. Three bract onion was found adjacent to unit FB1, Stebbins lomatium was found within and adjacent to unit 2309, Sierra valley lewisia was found adjacent to unit 2309, Sierra clarkia was found adjacent to unit 1456, and Coleman’s piperia was found in units 2309, 2336 and 2368.
