RICHARDS PEAK UNIT PRESCRIPTION 



Sale Name: Richards Peak Unit Nuniber(s): 2 



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



Elevation: 3700 Slope: 60% Aspect: NE, N 



Habitat type: ABLA/LroO Acres: 32 



Soils: Andic Ustochrepts, Andic Eutroboralfs. Soils are deep and well drained. Subsoils are 

 very gravelly clay loams and sandy loams. Soil erosion hazard and sediment delivery efficiency 

 are moderate. 



Description of existing stand: The unit consists of uneven-aged stand of Douglas-fir (95%) with 

 scattered western larch and lodgepole pine (5%). The overstory averages 220 trees per acre with 

 an average age of 130 years and an average diameter of 10 inches. Stocking is uniform 

 throughout with few breaks in the overstory canopy. Tree growth and vigor is declining in most 

 overstory due to overstocked stand conditions. Understory is scattered and clumpy in 

 distribution. Douglas-fir is the most common understory species with minor components of 

 lodgepole pine and grand fir. Forest health issues are mainly bark beetles with both mountain 

 pine beetle (lodgepole) and Douglas-fir beetle present. Their numbers are currently at endemic 

 levels but appear to be increasing. 



Treatment Objectives: 



1. Retain 10-30 trees per acre to provide a seed source for natural regeneration, favoring 

 western larch. 



2. Promote regeneration of western larch in openings. 



Prescribed Treatment: Seed Tree 



Harvest method: Cable logging unit. Harvest method will consist of individual tree 

 selection. Logging will use existing road along top of unit. Most of anchor trees in harvest 

 unit above road were cut in the 1980's. Few anchor trees remaining. The Forest Officer will 

 approve landing locations prior to use. Seed tree harvest will focus on removing the co- 

 dominant, intermediate, and suppressed trees of poor form and vigor. The healthiest 10 to 

 30 overstory trees per acre will be left to provide a seed source for natural regeneration. 



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

 under the State Fire Hazard Reduction Law. Whole tree yarding, lopping and scattering of 

 tops, or a combination of methods may be used to achieve desired results. Purchaser will 

 pile slash at landings and State crew will bum. 



Site Preparation: May prescribe bum unit if slash loading after logging is capable of carrying 

 fire.
