Isolated seed-bearers should on no account be felled unless there 
is sufficient crop of young growth on the ground, and it is desirable 
to clear away the coA’er from them. 
5. Dead trees should be worked out along with the green trees 
marked on the areas. 
Note. — In many cases the removal of dead trees from any portion of the forest 
is left to the discretion of the Conservator. Thus, in certain Central Provinces 
working-plans the following prescription occurs : — “ The removal of dead and dying 
trees may be allowed in such places and under such circumstances as may be sanc- 
tioned by the Conservator.” 
But it should be prescribed whether dead trees of exploitable size 
are to count against the possibility or not. 
(it) Special Rules. 
1. When the object of management, as for instance in the case of 
certain Burma teak forests, is to produce a certain amount of timber 
of large dimensions the following rule may be introduced : — 
Sound vigorous trees if standing in localities from which 
they can be easily extracted should not be marked for felling unless 
they show signs of cessation of growth. 
2. When, as in the Burma teak forests, girdlings are carried on 
in advance of the fellings, some prescription has to be introduced in 
order that the fellings may keep pace with the girdlings. The fol- 
lowing rule may then be prescribed: — 
The progress of girdlings in each sub-periodic block should 
be regulated by the progress of extraction of trees girdled during 
the previous sub-period, girdling operations being so controlled 
that marketable stems do not remain standing for more than 3 years 
after girdling. 
3. It frequently happens that where systematic working is first 
introduced, and especially in the case of remote forests, the demand 
is not always sufficient to absorb the whole of the prescribed yield 
of the forest. In such cases, the following provisions taken from 
Mr. Morgan’s Working Plan for the Motinala forests of the Mandla 
Division, Central Provinces, though not altogether sylviculturally 
correct, may be found useful : — 
The annual coupe may be kept open for 2 years; after the 
expiry of that period, such portion thereof which, in the opinion of 
the Conservator, has not been fully worked over will be brought
