RICHARDS PEAK UNIT PRESCRIPTION 



Sale Name: Richards Peak Unit Number: 5 



Location- Section 16 TWP: 24N RGE: 27W Subd: 



Elevation: 5300 Slope: 30% (10%-45%) Aspect: SW, W 



Habitat type: ABLA/XETE, PSME/SYAL Acres: 15 



Soils: Andic Cryochrepts. Soils are well drained and moderately coarse. Surface layers are 

 formed in volcanic ash influenced loess. Subsoils contain 65 to 90 percent rock fragments. 



Description of existing stand: The unit consists of even-aged stand of Douglas-fir. Scattered 

 lodgepole pine are also present. The overstory averages 1 75 trees per acre with an average age of 

 100 years and an average d.b.h. of 12 inches. Stand is densely stocked and uniform throughout. 

 Tree growth and vigor is declining in overstory due to overstocked stand conditions. Understory 

 is scattered and sparse due to closed canopy conditions of the overstory. The main forest health 

 issues are bark beetles. The mountain pine beetle is currently active in the lodgepole pine 

 overstory and scattered mortality of older Douglas-fir from the Douglas-fir beetle can also be 

 found. 



Treatment Objectives: 



1. Thin overstory to reduce overcrowding and improve tree growth and vigor. 



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 fuels per acre after 

 freatment. 



Prescribed Treatment: Commercial Thin 



Harvest method: Ground based logging unit with a small area below the bottom road that 

 will have to be cable logged. Harvest method will consist of individual tree selection. Trees 

 will be harvested using existing logging roads. The Forest Officer will approve skid trail and 

 landing locations prior to use. The commercial thinning treatment will remove intermediate, 

 suppressed and less vigorous trees to provide more growing space and nutrients for 

 remaining trees. 



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, dozer or excavator piling, or a combination of methods may be used. Purchaser 

 will pile slash at landing and State crews will bum.
