This THP is a few miles SE of Arcata, CA and about 6 miles NE of Eureka, CA at an elevation of 680 to 1,500 feet.  Green Diamond Resource Company is planning a mostly clearcut tractor and cable logging operation on steep and unstable slopes in redwood, Douglas fir, Sitka spruce, grand fir and western hemlock forests.  The THP area flows into the Jacoby Creek and Mad River watersheds which are listed as impaired watersheds for sediment, temperature and turbidity.  There are 8 landslide terrain sites in the THP area including 6 shallow rapid landslides, and 2 deep seated landslides.  Green Diamond Resource Company is planning to use temporary roads and landings during the winter period, and re-construct a section of road with a fill slope failure across an unstable area.  Six road drainage sites are planned for work including rocking, dip construction, ditch cleaning and culvert repair/replacement.  There is a great blue heron rockery .8 miles NE of unit A, and southern torrent salamanders are known to occur in or immediately adjacent to units A, C and E.  Spotted owl nesting territories are located within .25 miles of units A, D and G, and within .5 miles of units B, C, E and F.
