RICHARDS PEAK UNIT PRESCRIPTION 



Sale Name: Richards Peak Unit Number(s): 1 



Location - Section 4 TWP: 24N RGB: 27W Subd: 



Elevation: 3900 Slope: 15% (0-25%) Aspect: N, NW 



Habitat type: ABLA/LIBO Acres: 97 



Soils: Andic Eutroboralfs. Soils are deep and well drained. Texture is volcanic ash influenced 

 gravelly silt loams. Soil erosion and sediment delivery efficiency are moderate. 



Description of existing stand: The unit is an old shelterwood harvest unit from the late 1980's. 

 The overstory consists of approximately 10 Western larch scattered per acre with scattered 

 Douglas-fir also present. The 130-year-old Western larch average 16 inches diameter and 90 feet 

 in height. There are approximately 2,200 trees per acre in the understory, consisting of western 

 larch, Douglas-fir, grand fir, and alpine fir. No major insect and disease problems noted. A few 

 of the overstory larch are infected with dwarf mistletoe. 



Treatment Objectives: 



1 . Remove overstory to improve tree growth and vigor in understory. 



2. Protect soil productivity by minimizing soil displacement, compaction and erosion, and 

 site productivity by retaining 10-15 tons of down woody debris and fine ftiels per acre after 

 treatment. 



3. Retain 1 to 2 overstory western larch per acre for snag recruitment. 

 Prescribed Treatment: Seed Tree Removal 



Harvest method: Ground based logging unit. Overstory trees will be individually marked 

 and those trees removed will be skidded to nearest landing along existing roads. Skid trails 

 will use natural openings in the understory to reduce damage to residual. Overstory larch 

 will be left in clumps adjacent to wet areas and streams that bisect the unit. Landing and 

 skid trail locations will be approved prior to use by the Forest Officer. 



Hazard Reduction: Purchaser will be required to meet hazard reduction standards as applied 

 under the State Fire Hazard Reduction Law. Lopping and scattering, skidding tops to 

 landings, or a combination of methods may be used. Purchaser will pile slash at landing and 

 State crews will bum. 



Site Preparation: None prescribed for this entry 



Regeneration: None prescribed for this entry. Understory already stocked.
