HSG (Harvest Schedule Generator) is a spatially referenced forest inventory projection tool developed by Tom Moore and Cary Lockwood of the Petawawa National Forestry Institute. This tool is designed to assist forest managers and others in the design and evaluation of forest management strategies.

HSG differs from conventional forest simulation models, in that the spatial identity of individual stands is maintained as a forest is projected in time. Benefits of this spatially referenced approach include:

In HSG, each stand is modelled as a group of components which are grown independently along user-defined yield curves. Though components are usually cohorts of trees expected to follow similar development patterns, they may also be defined by other parameters such as water yield or wildlife habitat. In this way HSG can be used to project future yields of non-timber values on a stand-by- stand basis.

HSG contains a suite of programs designed to assist the user in preparing inputs, running simulations and generating queries that graphically display and map simulation results. This PC version generates IDRISI compatible datasets that may be analyzed and displayed using the full range of tools from the IDRISI GIS.

The software system is being distributed in two versions:

These two version have similar functionality, but the full version includes: additional software to support large datasets (using virtual memory management); full documentation; and full telephone support.
