CHAPTER V 



PRACTICAL SYLVICULTURE, OR REGENERA- 

 TION OF WOODLOTS 



Forest regeneration is the renewing or restoring of 

 forests. It is conducted in two ways, — separately, or in 

 combination. The two methods are called "natural 

 regeneration," when the new wood crop is started naturally 

 by self sown seed or by stump shoots, and "artificial re- 

 generation," when the wood crop is started by sowing 

 seeds or by planting seedlings or cuttings. 



NATURAL REGENERATION. FigS. 24-28 



A forest already established is implied in natural re- 

 generation. The operations consist in so treating the 

 woods that a new crop of trees becomes established as 

 the old crop is cut and utilized. There are several 

 systems of handling woodlands, depending on the 

 nature of the soil and climate and the kind of trees. 

 Some trees reproduce naturally from seed and stump 

 shoots, others from seed only. For this reason, a forest 

 or woodlot must be treated according to the kinds of trees 

 that are present. 



The systems or methods used may be called 



1. Selection system. 



2. Strip system. 



3. Group system. 



4. Coppice or sprout system.
