 P, viiich are modif icn tions of the fundamental metliods according to 

 and time (speed). 



(b) The fundamental forms or systems group as follows: 



(1) Clear cut with reproduction after the crop is removed, 

 leac'ing to -n even-n^ed form of forest. 



(2) Shelter^vood &ftSt&& v;ith reproduction before trie entire 

 crop is removed also le^ds to an evcn-a^cd form of forest. 



(3) 3e3 action system with reproduction continues all the 

 time; where the stand is n^ver removed entirely it leads to a many-aged 

 form of forest.
