Classification. 



The various trees on an area of even-aged high forest may be 

 classified as : 



I. Dominating trees. This class includes all trees which 

 form part of the uppermost canopy. It contains the following 

 classes of trees : 



(1) Healthy trees with a normal crown development and 



good boles. 



(2) Trees with an abnormal crown development or badly 



shaped boles. 

 In this latter class are included : 



(a) trees whose crown space is cramped by neighbouring 



trees ; 



(b) badly shaped old advance growth ; 



(c) trees whose general development has been faulty, e.g., 



with double leaders, etc.; 



(d) thin and spindly trees ;
