THP 1-16-127 HUM (Wiregrass East THP) Green Diamond Resource Company, 213.9 acres; 69% rehab, 26% selection, 5% no-harvest, misc roadside logging.  Toss-up Creek (HUM: T7N R2E Sec.24; T7N R3E Sec.19, 29, 30, 32).  Wet weather operations, moderate erosion hazard, steep slopes up to 65%, steep roads, landslide terrain, 9 road drainage work sites, impaired 303.d watershed, herbicides, coho watershed, spotted owl, southern torrent salamander, trees up to 30" dbh.  Estimated public comment deadline: 01/25/17. VIEW

This THP is a few miles north of the Highway 299 coast range summit between Arcata, CA and Willow Creek, CA at an elevation of 640 to 3,400 feet.  Green Diamond Resource Company is planning a mostly clearcut (rehab) feller buncher, shovel and cable logging operation on steep and unstable slopes in Douglas fir and western hemlock forests.  The THP Area Flows into Redwood Creek which is listed as an impaired watershed for sediment and temperature.  There is a small landslide area in unit A that originates from a fill slope off a road into a class II (mid sized) watercourse area.  Green Diamond Resource Company is planning to use temporary roads and landings during the the winter period.  Nine road drainage sites are planned for work including rocking, dip construction, ditch cleaning and culvert repair/replacement.  Southern torrent salamanders were reported in unit D.  There are seven spotted owl nesting territories within 1.3 miles of the THP area, including nesting territories within .5 miles of units F and G.  This THP is just north of Green Diamond Resource Company’s recently proposed Long Prairie THP 1-16-128 HUM.

THP 1-16-128 HUM (Long Prairie THP) Green Diamond Resource Company, 157.4 acres; 49% clearcut, 28% selection, 18% rehab, 4% no-harvest, 1% roadside logging.  Long Prairie Creek (HUM: T6N R3E Sec.5, 6, 7, 8).  Wet weather operations, moderate erosion hazard, steep slopes up to 65%, steep roads, landslide terrain, road failure sites, 20 road drainage work sites, impaired 303.d watershed, coho watershed, spotted owl, pacific fisher, southern torrent salamander, red tree vole, trees up to 40" dbh.  Estimated public comment deadline: 01/25/17. VIEW

This THP is about a mile south of the Highway 299 coast range summit between Arcata, CA and Willow Creek, CA at an elevation of 1,200 to 2,200 feet.  Green Diamond Resource Company is planning a mostly clearcut feller buncher, shovel and cable logging operation on steep and unstable slopes in Douglas fir and grand fir forests.  The THP areas flows into the Mad River which is listed as an impaired watershed for sediment, turbidity and temperature.  Seven landslide terrain sites were found along the road system and within units B and C, including several unstable areas along the K&K Road, a fill failure from a poorly designed skid trail crossing, and several road related cut slope failures.  Green Diamond Resource Company is planning to use heavy equipment in unstable areas to re-align a portion of the K&K 95.49 Road around an unstable area, re-construct a failed class II (mid sized) watercourse crossing and fill failure along the NW portion of Road 13, and re-open portions of the K&K 95.49L Road that were blocked by cut bank failures.  Two roads are proposed that have average grades above 15% with pitches of 20% or greater for over 500 feet in units C and E.  20 road drainage sites are planned for work including rocking, dip construction, ditch cleaning and restoration of washed out crossings.  A pacific fisher was reported within unit C, red tree voles have been observed in units C and D, and southern torrent salamanders are known to occur immediately adjacent to unit D.  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, and within .5 miles of unit E.  This THP is just south of Green Diamond Resource Company’s recently proposed Wiregrass East THP 1-16-127 HUM.
