Evaluation of agroforestry options for three tree species

Abstract

Information on tree growth rates, economic returns and the effects of trees on pasture for radiata pine, Australian blackwood and Eucalyptus fastigata were analysed to assess the economic returns of using these tree species within a hill country farming operation. Under the assumptions made, all three species options were more profitable in the long run than sheep and beef farming. Radiata pine produced the greatest return, large increases in log prices or yields of other tree species being required to give equal profit. The results of the analysis and market information emphasise the importance of good site selection and silviculture in the production of high quality timber. For some species these requirements may not fit on-farm production systems or be economically attractive.
