Forest harvest scheduling is a complicated management exercise because of the diverse and competing uses of forest resources, such as economic productivity, recreation and flora and fauna sustainability. In an effort to ensure the long-term viability of forest resources, restrictions are typically placed on the size of harvest areas, green-up intervals and proximity between disturbed areas in the United States. In order to satisfy consumer demands and maintain spatial and temporal restrictions, forest planners rely widely on optimization models to develop harvest schedules. A problematic element of work to date, however, is that spatial information relied upon in such analysis is typically uncertain in many ways, particularly spatial location and harvest unit boundaries. This paper develops new optimization models that explicitly account for spatial uncertainty in harvest scheduling. Application results demonstrate the effectiveness of this new perspective, enabling potential spatial uncertainty impacts to be better understood in management planning.
