No harvesting would take place adjacent to 

 any lake in the proposed area, except: 



in the area where cabinsite development is 

 proposed along Murray Lake 

 where requested by Beaver Lake cabinsite 

 leaseholders to remove hazard trees and 

 reduce ladder fuels. 



The silvicultural treatments are designed to 

 retain the multistoried structure of the area 

 and retain and perpetuate species diversity. 

 Harvest units would be designed with irregu- 

 lar shapes to better emulate natural distur- 

 bances. The locations of the harvest units, 

 with the exception of road right-of-way clear- 

 ing, are the same for both action alternatives. 



Both action alternatives would harvest ap- 

 proximately 4.5 MMBF of timber from 19 

 harvest units distributed over approximately 

 1,130 acres. Harvest units would range in size 

 from 4 to 169 acres. These 19 harvest units 

 may be divided among several different 

 timber sale contracts. Vegetation along open 

 roads would be retained, when possible, to 

 reduce impacts to visual quality and maintain 

 security for big game. 



PROPOSED SILVICULTURAL 

 TREATMENTS 



1 



The action alternatives use combinations of 6 

 silvicultural treatments. Figure II-l - Graphical 

 Reproduction of Silvicultural Treatments provides 

 a visual representation of how these treated 

 areas may appear following harvesting. The 

 visualizations are only a qualitative approxi- 

 mation of what would be expected to occur on 

 the ground due to the variations and diversifi- 

 cation of the stands treated in this project area. 

 Each visualization portrays the geographical 

 distribution of the treatment effects across a 

 harvest unit. Keep in mind that this is a 

 representation of the remaining distribution of 

 trees and that 1 tree from the visualization 

 does not equate to 1 tree on the ground. 



Clearcut with reserves - This treatment is pre- 

 scribed in densely stocked lodgepole pine 

 stands. Reserve trees would include vigorous 



trees of varying age classes of species other 

 than lodgepole pine and large snags. Small 

 pockets and strips of the existing stands would 

 be retained within the harvest units to help 

 break up the openings and create more- 

 irregular shapes that emulate natural distur- 

 bances. 



Seedtree with reserves - Large western larch, 

 Douglas-fir, western white pine, and ponde- 

 rosa pine would be retained, individually and 

 in clumps (approximately 6-10 trees per acre), „> 

 to provide a seed source, future snags, and 

 cavity-nesting sites. Existing snags and small 

 clumps of younger trees would also be re- ... ;» 

 tained to provide for both structural and 

 species diversity. < 



Modified seedtree/sheltenoood with reserves - 'j 

 Large western larch, Douglas-fir, western >] 

 white pine, and ponderosa pine would be 

 retained, individually and in clumps (approxi- 

 mately 6-10 trees per acre; in shelterwood 

 areas, up to 40 trees per acre) to provide a seed 

 source, future snags, and cavity-nesting sites. 

 Existing snags and small clumps of younger 

 trees would also be retained to provide for i^ 

 both structural and species diversity. i} 



Commercial thinning - 40% to 60% of the exist- s, 

 ing overstory would be harvested to reduce i 

 the stocking density, improve growth rates :' 

 and vigor, and increase the serai composition t 

 in the stand. 



Croup selection with reserves - Small openings, .• 

 up to 5 acres in size, would be created in the 

 existing stand to promote regeneration and/or 

 release established regeneration. Reserve trees 

 would include vigorous trees of varying age 

 classes in all species present. Snags and large 

 serai trees that have a high potential to become 

 cavity-nesting sites in the future would be 

 retained. 



Improvement cutting - Selective harvesting 

 would be done to reduce stocking density, li 

 increase the serai component in the species 

 mix, and remove trees that are at high risk for 

 value loss and mortality or are showing signs 

 of low vigor. ;
