treme detail, several examples are given below of costs and returns that can be anticipated conservatively as of 1943 in the Concepcion and similar areas. Future value of 855 pesos, 30 years hence @ 6% = 4,911 @ 6% = Total cost, including 6% interest = Anticipated Returns Per Hectare Expected yield, 30 years hence: 100,000 board feet of sawtimber at a 1,423 6,334 30,000 Ratio of anticipated net return to total cost, including interest at 6% = 4.7 to 1. In order to simplify the estimates and to keep them conservative, no allowance is made for the income derived from thinnings before removal of the final crop, although this is a positive source of net return. Managed for pulpwood, the conservatively anticipated costs of growing and returns from Insignis Pine on a 25-year rotation are as follows: Future value of 855 pesos, 25 years hence @ 6% = Total cost, including 6% interest = Pesos 3,670 988 4,658 Anticipated Returns per Hectare Expected yield, 25 years hence: a margin of 30 pesos each for Ratio of anticipated net return to total cost, 15,000 Eucalyptus Globulus Managed for fuelwood, the following costs of growing and returns from Eucalyptus might be expected conservatively on a 20-year rotation: Future value of 855 pesos, 20 years hence @ 6% = Total cost, including 6% interest = Anticipated Returns per Hectare Expected yield at 20 years: 400 cubic meters of fuelwood 2,742 662 3,404 at a margin of 30 pesos each for stumpage, profit and risk = 12,000 Ratio of anticipated net return to total cost, including These estimates do not show the best or the poorest planting opportunities, but are given here to illustrate what may be anticipated conservatively over rather broad areas. |
