Characterising and regulating spatial structure of forested landscapes is an important step towards shifting the traditional focus of forest management from managing resource hows, such as timber and wildlife habitat, to managing forests. Concerns about maintenance of forest ecosystems, biodiversity and wildlife, as well as economic benefits have lead to the concept of forest landscape management. The focus of forest landscape management, like contemporary management, is the management of forest structure. Forest landscape management, however, is based upon the premise that resource Bows as well as biodiversity levels and ecosystem processes are determined by the array and spatial arrangement of forest conditions, i.e. spatial structure, and its change over time.
