This THP is about 17 miles east of Eureka, CA and Highway 101 at an elevation of 1,860 to 3,560 feet. Green Diamond Resource Company is planning a mostly clearcut tractor and cable logging operation on steep and unstable slopes in Douglas fir forests. Trees up to 84" dbh were reported in unit H, trees up to 72" were reported in units J and M, trees up to 60" dbh were reported in units A, B, C, E and L, and trees up to 52" dbh were reported in unit I. The THP area flows into the Mad River which is listed as an impaired watershed for sediment, turbidity and temperature. There are 32 unstable landforms in the THP area including 15 shallow rapid landslide terrain sites, 17 deep seated landslide terrain sites, and multiple road failure sites with bank sloughing, fill failures and cut bank failures. Green Diamond Resource Company is planning to use an existing road inside a class II (mid sized) watercourse area in unit I for loading, decking and yarding purposes, and use the SC 2200 Road inside a class II (mid sized) watercourse area adjacent to unit A for loading, decking and yarding purposes. They also are planning to use roads and landings during the winter period, and use ground based equipment to construct and/or re-construct a road across an unstable area in unit K for yarding and decking operations. 35 road drainage sites are planned for work including rocking, dip construction, ditch cleaning, culvert repair/replacement and restoration of washed out crossings. In 1996, a Cooper's hawk was reported 2.3 miles SE of the THP area, in 2000, a sharp shinned hawk was reported 1.4 miles SE of the THP area, and a golden eagle was recently spotted 1 mile SW of the THP area. Red tree voles were detected in units F and L in 2003, and in units D and E in 2004. There are 8 spotted owl nesting territories within 1.3 miles of the THP area, including spotted owl nesting territories within .25 miles of units A, B, C, D, E, F H, I and M, and within .5 miles of units G, J, K and L.
