SOILS 

 COMPACTION 



• Logging equipment will not operate off forest roads unless soil moisture is less than 20%, frozen 

 to a depth that will support machine operations, or snow covered to a depth that will prevent 

 compaction, rutting, or displacement. 



• Existing skid trails and landings will be used where their design is consistent with prescribed 

 treatments and meets current BMP guidelines. 



• Designated skid trails will be required where moist soils or short steep pitches (less than 300 

 feet) will not be accessed by other logging systems. This will reduce the number of skid trails 

 and the potential for erosion. 



• Where designated skid trails are required, timber on the trails will be felled and skidded before 

 the remaining timber in a harvest unit is felled. This will define felling patterns, facilitate skid- 

 ding on designated trails, and reduce the harvest unit area impacted by skidding equipment. 

 Skidding plans are required to be in place prior to the start of logging operations. 



• Skid trail density in a harvest area will not exceed 15% of the total area. 



SOIL DISPLACEMENT „„^„ ,,,„,. ,,„^,n 



• To prevent displacement and erosion of topsoil, hard-track, ground-based skidding equipment 

 will not be operated on steep slopes (greater than 40% sustained over 300 feet). iS • 



• Brush piling with dozers requires use of an approved brush rake. . , ..v^ ».. .r.-.^ 'i 



• Designated skid trails will be required in all areas where tractor yarding is proposed. Existing 

 skid trails will be used when possible. 



• Lopping and scattering will be used for hazard reduction to retain woody debris onsite for 

 nutrient cycling.

EROSION

Ground-skidding machinery will be equipped with a winchline to limit the equipment-opera- 

 tion areas.

• Roads used by the purchaser will be reshaped and the ditches redefined following use to reduce 

 surface erosion. --^^ ^.^^ ^^^^ ^^^ , ^,^^.. 



• Drain dips and gravel will be installed on roads, as needed, to improve road drainage and , 

 reduce maintenance needs and erosion.
