c. Site Preparation 



Site preparation activities should be performed as soon as 

 possible following harvest. Depending on regeneration objec- 

 tives, either mechanical, chemical or burning techniques 

 should be utilized. Timing and method used should provide 

 for minimal soil disturbance and compaction to meet the 

 required objectives. 



d. Habitat Types 



Do not clearcut on any of the ponderosa pine habitat types 

 of on the Douglas fir/ rough fescue type. 



e. Soil types 



Do not clearcut on the following soil types: Krause, 

 Totelake, Coldcreek, Winkler, Sharrot, Rachert, Ashborn, 

 Nemote or Drexel . 



3. Seed Tree Cutting 



Seed trees, as the name implies, are trees left to regenerate a cutover 

 area by producing and dispersing seeds. Trees left as seed trees should 

 be vigorous, genetically desirable and of an age to produce adequate 

 quantities of viable seed. The understory may or may not be removed 

 after logging, depending upon species, condition, size, age and stocking. 



a. Specifications for Seed Tree Cutting 



1) Size: No restriction on size; however, economics of 

 logging and slash disposal must be considered. 



2) Boundaries: Logging roads and ridges make desirable 

 boundaries for fire control. When a ridge is used, the 

 cutting boundary should be placed slightly over the crest 

 as slash fires are very difficult to stop right on top of 



a ridge. Whenever a ridge cannot be a boundary, boundaries 

 should be blended to the physiographic features. 



3) Site Preparation: At least 50% of the cut area, distributed 

 uniformly over the harvest unit, should be scarified, preferably 

 by mechanical methods. If the area is harvested during the 

 winter, site preparation should be done the following summer, when 

 soil moisture is low, so as to minimize soil compaction. 



4) Habitat Types: Do not use this system on any of the ponderosa 

 pine habitat types nor on the Douglas fir/ rough fescue type. 



5) Soil Types: Do not use this system on the following soil 

 types; Krause, Totelake, Coldcreek, Winkler, Sharrot, Rachert, 

 Ashborn, Nemote or Drexel.
