however, up to an additional 40 acres may be salvage harvested if significant tree 

 mortality occurs as a result of insect infestation brought about by the fire. Harvest 

 may occur in up to 284 acres, 191 acres would be har\'ested with ground based 

 equipment and 13 acres with a skyhne harvesting system. (See Appendix A: 

 Figure A-3) 



Harvesting would remove fire killed or insect infested timber. Approximately 2 

 snags per acre would be retained to serve as snag recruitment. Trees selected for 

 snags would be greater than 21" dbh. If 2 snags over 21" dbh are not available 

 then the next largest available size tree would be left. 



Logging slash would be return skidded and dropped on skid trails in ground-based 

 units. 



This alternative would provide between $225,000-$3 15,000 in revenue to the 

 Common School Trust (estimated at $25-$30/ton). Additional revenue may occur 

 through subsequent harvest of insect infested timber in the analysis area. 



The table below outlines the status of acreage involved in this project.

2.6 Mitigation Measures of Alternative B: Harvest 



The following mitigation measures would be implemented through the 

 administration of the timber sale contracts. 



Harvest Unit General Design Mitigations 



• Cable hardest activities during the summer have a higher potential to cause 

 soil disturbance than winter cable harvest operations Slash and tops will be 

 retained within the cable corridors to mitigate these potential impacts. 

 Corridor spacing and layout will also be designed to best fit the terrain. 



• Use minimum SMZ width required by law as located in the field. 



• Protect all ephemeral draws, springs and wet areas with marked equipment 

 restriction zones (ERZ). Mark and maintain a Riparian Management Zone 

 (RMZ) along fish bearing streams (Wallace Creek) and specific sites with 

 high erosion risk adjacent to streams. Cable yard or winch-line all trees felled
