A recently developed simulation model was used to compare the volumes and present net worth of stands of Pinus radiata with final crop stockings of 100 stems/ha, 200 stems/ha, and 400 stems/ha grown in conjunction with understory pasture. Various site and silvicultural variables were altered, and the effects on present net worth calculated. Final crop stockings of 100 stems/ha gave the lowest timber yields, but were more profitable than the other treatments. The addition of estimated revenues from livestock grazed under the trees further favored the lower tree stocking. These preliminary results indicate a considerable level of compatibility between agriculture and forestry on NewZealand hill country. The model, when complete, will allow site and managementspecific evaluation of agroforestry proposals involving combinations of P. radiata and pastoral agriculture |
