dc.description.abstract The aim of this study was to assess the economics of controlling gorse in hill country, comparing the use of goat and sheep grazing to chemical control. The New Zealand environment has suited the growth of gorse (an introduced species) to such an extent that this plant has become a major weed problem throughout New Zealand. Traditionally, gorse has been controlled by spray programs, but this method has met with limited success. Recent research has shown the grazing of goats and sheep to be a possible alternative for gorse control. A simulation model was constructed which includes the physical and economic aspects of a hill country grazing system. Due to the limited data available a deterministic approach was taken. Extensive sensitivity analysis and experimentation was carried out to evaluate alternative control strategies under different price and production scenarios. The model was also constructed to be useful for future analysis and agricultural extension. The study concludes with a discussion of the results given both long and short term expectations. A brief outline of the scope for further study in this topic is also given. en
