It is hard to -plant foil -places in natural reproduction. (Pail 

 spot: a pl^ce where natural or artificial reproduction has failed). 



(3) If successful in reproduction the stand is too dense, 

 e,t lenst in spots,, competition in too ;,-ret for successful growth, and 

 may easily lead to a break-down, and therefore to the introduction of 

 fungi, insects, and in some cases to stagnation (in lodgepole). To avoid 

 these 'e should use early attention, vhich is expensive.
