is the oldest method of natural regeneration and was largely used 

 throughout Europe during the 15th and 16th centuries. It is 

 now seldom used in Europe except to supplement artificial regen- 

 eration and natural seeding from adjacent woods. It has been

largely used in the United States in recent years, but, in the 

 author's opinion, can result only in disappointment. Except with 

 the most resistant species, the seed trees left are liable to be 

 felled by the wind. The species must produce seed having great 

 carrying power, the soil must be receptive, and the reproduction 

 must be attained quickly or a growth of herbage will prohibit 

 later regeneration. 



The scattered seed tree method has proved most useful abroad 

 when used in connection with artificial regeneration (Fig. 8). 

 After clear-cutting with scattered seed trees, the area is either 

 planted or seeded with the species which is to become the domi- 

 nant part of the crop. The scattered seed trees are of other 

 species which through natural reproduction introduce age variety, 

 as well as variety in species, into the otherwise even-aged artificial 

 stand.
