Long Prairie Creek  (HUM: T7N R2E, Sec 25, 36; T7N R3E Sec 30, 31).  Winter operations, moderate erosion hazard, steep slopes up to 65%, landslide terrain, 23 road drainage work sites, impaired 303.d watershed, oversized units, herbicides, coho watershed, spotted owl, Cooper’s hawk, southern torrent salamander, coastal tailed frog, trees over 30” dbh.  Estimated public comment deadline: 07/01/19.

This THP is about 8 miles NE of Arcata, CA, just north of the Highway 299 coast range summit at an elevation of 1,600 to 3,310 feet.  Green Diamond Resource Company is planning a mostly clearcut tractor and cable logging operation on steep and unstable soils in Douglas fir and redwood forests. The THP area flows into the North Fork of the Mad River which is listed as an impaired watershed for sediment, turbidity and temperature.  There are 10 unstable areas including; 7 shallow rapid landslide terrain sites near the middle portion of the east boundary of unit B, 1 shallow rapid landslide terrain site near the southern portion of unit B by the K&K 152.56R Road, and 1 shallow rapid landslide terrain site along the eastern boundary of unit F. Green Diamond Resource Company is planning loading, decking, and yarding operations on existing roads within a class II (mid sized) watercourse area inside unit B, use 2 segments of existing skid roads inside a class II (mid sized) watercourse area which connects to a landing inside unit B, and construct a road near a wet area in unit F.  Ground based equipment is also proposed for use within a landslide terrain site (earth flow) inside unit B. Twenty three road drainage sites are planned for work including rocking, dip construction, ditch cleaning and culvert repair/replacement. In 2010, a Cooper’s hawk was reported 300 feet NW of unit A, and southern torrent salamanders and coastal tailed frogs are known to occur immediately adjacent to unit F.   There are 2 spotted owl nesting territories within 1.3 miles of the THP area.  This THP is just south of Green Diamond Resource Company’s Wire Canyon THP 1-19-065 HUM.

This THP is about 9 miles NE of Arcata, CA and a few miles north of the Highway 299 coast range summit at an elevation of 1,520 to 3,400 feet.  Green Diamond Resource Company is planning a mostly clearcut tractor and cable logging operation on steep and unstable soils in Douglas fir and redwood forests.  The THP area flows into the North Fork of the Mad River which is listed as an impaired watershed for sediment, turbidity and temperature.  There are 2 deep seated landslide terrain sites in unit A, and 2 shallow rapid landslide terrain sites in unit G.  Green Diamond Resource Company is planning to use ground based equipment on unstable areas (deep seated landslide terrain) within unit A. Six road drainage sites are planned for work including rocking, dip construction, ditch cleaning, and culvert repair/replacement.  In 2001, a red tree vole was spotted inside unit A, and in 2010, a Cooper’s hawk was reported .24 miles south of unit F.  Coastal tailed frogs were reported 2,400 feet downstream of unit G, and southern torrent salamanders are known to occur within 1,000 feet of units B and D.  There are spotted owl nesting territories within .5 miles of unit A.  This THP is just north of Green Diamond Resource Company’s Wire Fawn THP 1-19-068 HUM.
