lyo I'OREST REGULATION' 



Lodge Pole case, it is not possible to plan the fixed yearly cut for the 

 whole twenty-five year period. Selection of areas and order of their 

 cutting are determined by the purchasers, more than by the forester. 

 But the plan is now clear, the forester knows that he should make 

 efforts to bring up the cut to 40,000 acres per year, cut on selection 

 plan, take about a third of the stuff and sell about 180 million feet. 

 It is a safe plan to follow, it has a basis in the Growing stock and 

 growth of the forest as determined by species and site, and as meas- 

 ured and known. 



i. CJn this property of Western Yellow Pine with its good 

 sites and rapid growth silviculture will probably abandon the Selec- 

 tion Method after the first cutting over. In this case, by that time 

 there should be a complete division of the forest on the ground and a 

 reliable inventory so that Regulation can at once go to a regular 

 Area Allotment. Here again, it is desirable if not necessary, that the 

 large property be divided into several Working Sections, merely by 

 reason of size. A million acre forest will prove unwieldly as soon 

 as the markets make good forestry, in keeping with species and 

 sites, a practical enterprise. 



The foregoing will suffice to illustrate what is attempted in 

 Regulation of the cut, how the methods apply, and the good that is 

 accomplished. It is clear that in our large Wild Woods properties 

 it is not a matter of nire accuracy. Regulation can only secure a 

 fairly reasonable figure, safely based on actual conditions of the 

 forest and applicable under present conditions of market and means 

 of transportation. 



It is also evident that Regulation is adapted to the methods of 

 silviculture, that in the beginning with Selection Method, a simple 

 Area Regulation, a Modified Fixed Yearly Cut with Volume check 

 based upon Return and Rotation, and calculated by \'on Mantel's 

 formula is quite satisfactory. Also that simple A'olume Regulation, 

 whether based on \'on Mantel or the .Austrian Formula, tends to 

 an Area Regulation in time. As stated repeatedly. Regulation of the 

 cut tends toward Area Allotment, full or restricted, as soon as a 

 more intensive silviculture is made possible by a more complete and 

 dependable utilization. In all cases this Regulation of the Cut in 

 A^olume performs only one part of Regulation and does not replace 

 Division of the Forest and proper distribution of .\ge Classes.
