The comparative profitability of P. patula, P. taeda and P. elliottii stands in Zimbabwe

, : The comparative profitability of P. patula, P. taeda and P. elliottii stands in Zimbabwe. ForMat 7(1): 1-3

Profitability and growth were analysed for stands of Pinus patula, P. taeda, P. elliottii established on similar sites in Zimbabwe, assuming similar initial establishment, and timing, intensity and costs of silvicultural operations.

The cost of pruning to 6.7 m ht, compounded at 8% interest, is compared with recovery value (based on a premium paid for clear timber) for various pruning core sizes. It is concluded that the pruning core should be confined to 12.7-17.8 cm. Prunin...
