PRACTICAL FOREST MANAGEMENT. 



Allotment 

 to 



working 

 circles. 



Allotment 

 to periods. 



Descrip- 

 tion of 

 the grow- 

 ing stock 



regards particular blocks or compartments arid should bo noted. 

 Thus the upper portion of a slope near the top of the ridge may 

 require very different cultural treatment from the lower portion 

 towards the bottom of the underlying valley, although the differ- 

 ence of level above the sea may be slight. The aspect should 

 always be stated where it is well denned ; but in hilly ground a 

 single block often faces several points of the compass. The slope 

 may be stated in a single word. A slope is said to be gentle when 

 the inclination is not greater than about 1 in 6 ; it is steep when 

 more than 1 in 6 but not greater k than 2 in 3 ; it is very steep 

 when more than 2 in 3, and becomes precipitous when it reaches 

 lin 1. 



The working plan officer enters his provisional allotment to a 

 working circle which may be confirmed or altered as the field work 

 proceeds. 



In an exact similar way the working plan officer enters a 

 provisional allotment to periods, based on the description of the 

 growing stock, in the case of a working circle with periodic blocks ; 

 and at the conclusion of the field work a definite allotment is 

 finally made. 



The description of the standing crop should present to the mind 

 of the forester a complete picture of the state of the compartment. 

 In order to do this there are several points to be carefully attended 

 to, viz. 



Component species. 



Technical nature of the crop. 



Density. 



Age. 



Origin. 



The component species can be described in a few words 



" Sal mixed with some few sain." 



" Deodar mixed with blue pine in the upper part of the 

 compartment and with chir along the lower boundary." 



" Pure chir pine."
