CHAPTER VIII. 



KEGENERATION BY COPPICE. 



Regeneration by coppice, in its broadest sense, may be effected 

 by means either of stool-shoots or of root-suckers or of culms or of 

 pollards, or of any of their combinations. Regeneration by stool- 

 shoots is that most commonly employed, since all broad-leaved 

 species can grow up again in this manner, whereas only a limited 

 number of them can send up root-suckers and only the bamboos 

 produce culms, while pollarding is an entirely exceptional mode of 

 treatment. 



SECTION L 

 Regeneration by stool-shoots. 



Success in regeneration from the stool depends on ten main 

 factors as follows: (1) the species, (2) the soil, (3) the climate, 

 (4) the age of the stems cut back, (5) the healthiness and sound- 

 ness of the stools, (6) the longevity of the stools, (7) the manner of 

 cutting the stools, (8) the season for cutting, (9) the location of 

 the coupes, and (10) the presence of stores. 



1. Influence of the species. 



The conditions that regulate the relative facility with which the 

 different species grow up again from the stool have already been 

 fully studied on pp. 75-78, to which the student is referred. 



2. Influence of the soil. 



The soil affects reproduction from the stools by its fertility 

 an 1 suitability for the species in question and the repeated sudden 

 temporary arrests of vegetation it may bring about (see pp. 

 74-75). 



3. Influence of the climate. 



This influence is fully described on pp. 74-75 under the head of 

 "Repeated temporary arrests of vigour of crown." The more 

 vigorous the growth is during the intervals between these tem- 

 porary arrests of vegetative activity, that is to say, the more forcing 

 the climate is, the stronger will be the production of the stool- 

 shoots. 



4. Influence of the age of the stems cut back. 



This influence has been studied in detail on pp. 73 and 91-2.
