US PRACTICAL FOREST MANAGEMENT. 



khair) which cannot regenerate naturally on the site of an old 

 or mature crop. There are again extensive areas of scrub or semi- 

 ruined forests, where the regeneration becomes almost afforestation 

 in which it is advisable to remove the derelicts of the old crop 

 to ensure that the new and even-aged crop develops under the beat 

 conditions. For example, the extensive open heavy grass Tarai 

 forests in Kumaun, with simal as one of the principal species. 

 Again, certain light-demanding species such as teak and simal 

 cannot develop satisfactorily under even an open shelterwood of 

 mother trees, and here again clear-felling is indicated if other 

 essential factors are favourable. And, generally speaking, the 

 clear-felling system is most satisfactory of all systems for strong 

 light-demanders, wherever we have present the three essential 

 conditions : (1) suitability to the silvicultural requirements of the 

 species in that locality, (2) an intensive demand, (3) a guarantee of 

 the immediate successful regeneration of the annual coupe.
