larch seed tree areas and in clear cuts where seeding or planting is re- 

 quired. South facing slopes on dry sites will only be burned as a last re- 

 sort because of the difficulty of re-establishing reproduction on these 

 areas after burning. 



c. Dozer stripping will be done to remove grass sod and shrubs for seeding 

 and planting operations where required. Also, it may be used in seed 

 tree areas where sod has formed after the initial scarification or burning. 

 This stripping will entail peeling off the entire sod for the width of the 

 dozer blade and stripping 33<yo to 50% of the ground area. 



d. Laydown of cull or decadent understory will be the general practice prior 

 to any broadcast burn. This treatment results in a hot burn which is 

 necessary to bare up mineral soil for regenerating the stand. Also, 

 standitig burning of understory containing lodgepole stimulates this type 

 of reproduction because of the serotinous cones on these trees. This type 

 of treatment may be done either by dozers or by slashing with power saws. 

 The steeper ground and thinner stands will be the areas for power saw 

 slashing. Laydown without burning may be done where there is sutiicient 

 small reproduction present of qu£.lity species to regenerate the area. 



e. Chemical spraying for brush eraaication is not necessary on most com-^ 

 pany timberiands. It has proven eiiective on several smaller area& 

 along streams anf will be use-i in these locations to remove brush for re- 

 generating the stand or to reltbse reproduction under the brush. 



f. Poisoning rooents with 1080 poisoned grain has proven very eilective in 

 curtailing rodent populations. This method will be employed prior to all 

 seeding operations to protect the seed aur.ng the germination pcrion
