    Description

    A conceptual model of hardwood rangelands as multi-output resource system is developed and used to achieve a synthesis of Integrated Hardwood Range Management Program (IHRMP) research. The model requires the definition of state variables which characterize the system at any time, processes that move the system to different states, outputs (at the site and the landscape level) which are produced by processes as the system changes state and values which are derived from outputs or directly from the system's state. Processes can be further categorized as intensive (i.e. involving function within the hardwood system) or extensive (involving reduction in the extent of the hardwood system). The incidence of processes sets the model in motion. Research projects are evaluated by the extent to which they contribute to the measurement of model components and the elucidation of the relationships between them.
