104 SILVICULTURE-METHODS OF NATURAL REPRODUCTION 



right time to open up the crown cover, stimulate seed production, and 

 prepare the soil for seed germination. It can be applied in this coun- 

 try to oak, white ash, and white pine where market conditions are 

 favorable. It is especially applicable to parks and estates where 

 aesthetic effects are desired. It is used in the South, in the Black 

 Hills of South Dakota, in New England, and in the Douglas fir region 

 in the Rocky Mountains. 



FIG. 53. Photo taken approximately 20 years after area was selectively logged, 

 the slash was carefully piled and burned and the area protected from fire. There 

 is excellent reproduction of young growth on the ground and there is much more 

 rapid growth attained in the remaining trees through the opening of the crown 

 canopy and giving more light to the remaining trees. Stumps were cut low and 

 close utilization was practiced. Photo taken in ponderosa pine stand in western 



Montana. 



4. Selection Method. By this method, the oldest and largest trees 

 in the stand are selected for cutting. Single trees or groups are cut. 

 The stand is never completely clear cut during logging operations. 

 A typical and continuous uneven-aged forest is grown. All ages are 

 represented, generally from seedlings to nearly mature trees. It is 

 best adapted to tolerant or shade-enduring species. A cutting is made 

 each year or at regular periodic intervals under intensive forms of 

 application. If cuttings are at frequent intervals, logging may be very
