Summary: A computerised yield model was prepared for Pinus radiata in the Western Cape Province of South Africa, on the basis of measurements of the CCT (Correlated Curve Trend) plots carried out over many years by the government forest service. With this model the yields were estimated for different site qualities and for many different combinations of planting espacement, thinning programme and clearfelling age; and the profitability was estimated in terms of rate of return and net present value, for various combinations of timber values and silvicultural costs. The heavy thinning programmes were consistently more profitable.
