MANAGEMENT OF LOBLOLLY PINE FORESTS. 



ADVISABILITY OF MANAGEMENT. 



The profits to be expected from forest management of loblolly pine 

 are shown in Tables 19 ; 20, 21, 22, 23, and 24, which indicate the 

 possible money returns and corresponding compound interest rates 

 from properly managed stands. Tables 19, 20, and 21 give returns 

 to be expected from fully stocked stands at different ages on Quality 

 I, II, and III soils, where the product is to be manufactured into North 

 Carolina pine rough lumber, cutting all trees 7 inches and over in 

 diameter breast-high, while Tables 22, 23, and 2-1 give ihe same where 

 the product is to be cut and sold as ungraded lumber and where all 

 trees 5 inches and over in diameter are cut. 



Table 19. — Net profits per acre and corresponding compound interest rales from loblolly 

 pine, for different initial investments, rotations, and distances from market.

1 Cost of establishing a loblolly pine stand, either by natural or artificial reproduction. 



2 Three cents per acre annually for administration "(including fire protection), and 6 mills on the dollar 

 (full valuation) annually for taxes, which is above present average tax for the region. 



3 Stumpage value as given in Table 15, less original cost of formation and total cost of administration and 

 taxes. Where no net profit is shown, a loss is i ndicated. 



* Calculated by formula p=100 | /- l - ~ .— II, where p=compound interest rate, m=number of
