This THP is about 14 miles NE of Trinidad, CA and 17 miles SE of Klamath, CA near Orick, CA and Redwood National Park at an elevation of 980 to 2,260 feet.  Green Diamond Resource Company is planning a tractor and cable logging operation on steep and unstable slopes in redwood and Douglas fir forests.  The THP area flows into the Klamath River which is listed as an impaired watershed for sediment, temperature, dissolved oxygen and nutrients.  There are 25 unstable areas within the THP including; 5 shallow rapid landslide terrain sites and 2 deep seated landslide terrain sites in unit A, 5 shallow rapid landslide terrain sites and 1 deep seated landslide terrain site in unit B, 2 shallow rapid landslide terrain sites and a cut slope failure in unit C, 5 shallow rapid landslide terrain sites and 1 deep seated landslide terrain site in unit F, and 4 shallow rapid landslide terrain sites in unit H.  Multiple road failure sites exist including bank sloughing, erosional voids, gullying, fill failures and cut bank failures.  Green Diamond Resource Company is planning to construct and use temporary roads and landings during the winter period, and construct and/or re-construct steep segments of roads on slopes over 65% grade.  23 road drainage sites are planned for work including rocking, dip construction, ditch cleaning, culvert repair/replacement and restoration of washed out crossings.  There is marbled murrelet habitat on Redwood National Park lands within .25 miles of the mainline TT-100 Road, and Del Norte salamander habitat in unit B.  Three spotted owl nesting territories are located within 1.3 miles of the THP area, including spotted owl nesting territories within .5 miles of units E and H.
