88 SEEDING AND PLANTING 



forest may be of little value and the introduction of other species 

 may be desirable. In instances of this sort, seeding or planting 

 must be resorted to in order to supplement the natural reproduc- 

 tion from seed. 1 It is often discernible at the outset that certain 

 portions of a given area are not suitable for natural regeneration. 

 In such cases they should be artificially restocked at once or dur- 

 ing the period that natural restocking from seed is being attained 

 on the remainder of the area. It sometimes happens that during

the progress of natural regeneration under a shelterwood or by 

 seed from scattered seed trees, windfall or other damage occurs 

 which makes it necessary to assist natural regeneration by artifi- 

 cial means (Fig. 16). 



1 The stands of beech in the Sihlwald near Zurich, Switzerland, and in the 

 Wienerwald near Vienna, Austria, are from natural regeneration. Because 

 of the low price of beech and the enhanced value of softwoods at the present 

 time, the natural reproduction of beech is supplemented by planting pine, 

 spruce and other softwoods, usually in groups in the more open places.
