 possibilite. 



The following classification of methods of regulating the cut may be 

 recognized: 



Allotment methods, when a rotation is fixed and for a given year or 

 period of the rotation a certain area, a certain amount of stock, a cer- 

 tain number or size of trees is allotted to be cut. 



Normal stock or Formula methods, when the amount of cut is deter- 

 mined by comparison of actual with normal conditions and the cut is in 

 part regulated by a volume formula for a rotation or equalization 

 period. 



Individualizing or Stand methods, when each stand is investigated for 

 its financial maturity and designated for cutting, provided other age 

 classes are in existence to assure continuity of crops. 

 Removal cutting. See Reproduction, Shelterwood method. 

 Removal stage. Sec Reproduction, Shelterwood method. 

 Rent. In forest finance, the income per acre secured as an annual return 

 from a forest or stand under management, calculated either as forest 

 rent or soil rent. 



Forest rent is the net income {q. v.) from a forest organized for sus- 

 tained yield, without interest charges on the forest capital — book- 

 keeper's balance — • the forest, i.e., soil with a stand or growing stock, 

 being conceived as the forest capital, and the rent as the total interest 

 earned by it. 



G., Waldrente. 



Soil rent is that part of the income (or balance) from a managed forest 

 which remains as interest on the soil capital alone after all expenses 

 with compound interest have been deducted, the soil alone being con- 

 ceived as the capital. 



G., Bodenrente. 

 Reproduction. 1. The process by which a forest is renewed. 



Natural reproduction is the renewal of a forest by self-sown seeds or 

 by sprouts. See also Advance growth. 



Syn.: regeneration. 



G., natiirliche Verjiingung. F., regeneration naturelle. 



Artificial reproduction is the renewal of a forest by direct seeding 

 or planting.
