| Abstract: | The impact of imposing spatial wildlife constraints on long-range timber management schedules is examined for a public forest in northern Virginia under varying levels of a wildlife habitat constraint. Linear programing-based timber management scheduling models are solved using standard linear programming , mixed-integer programming with computer-determined stand allocations, and mixed-integer programming with predeterminend stand allocations in order to determine the extent to which the failure to consider explicitly the spatial aspects of a forest management problem with wildlife concerns may lead to an overestimation of timber production capacity. Findings indicate that present net value is overestimated by 1-8% to 21-4% and annual sawtimber harvest volume is overestimated by 2-6% to 13-5% when the standard linear programming approach is used. |
