Abstract

An approach to assessing the financial viability of bush clearing on game ranches in savanna regions is presented, using data on the rates of change of herbaceous phytomass and tree density following bush clearing. Financial gain is calculated from an increase in grazing capacity with an increase in herbaceous phytomass. The financial gain is offset against the financial loss due to a decrease in browsing capacity with a decrease in bush density. Profitability is calculated by calculating the net present value of the net financial gain over the effective duration of the bush clearing exercise. Shortcomings in the approach are identified and a need for more appropriate long-term data is indi-cated.

Keywords
