GISForman+ (Geographic Information System linked FORest MANagement plus) is a hybrid forest simulator, drawing from both spatial and aspatial forest modelling experience. Its spatial nature originates from GISFORMAN and uses the ArcInfo GIS, while much of its management control functionality is modelled from FORMAN+1, both simulators based on the FORMAN software. GISForman+ allows forest planners to forecast forest response to spatial management strategies. It applies rule-based harvest and silviculture intervention strategies to a forest model of stand conditions and locations, growth patterns, and intervention (treatment) alternatives. Using a spatial forest model, GISForman+ can model harvest size opening limits and the resulting harvesting restrictions. This user manual describes the concepts behind GISForman+, explores the software's forest model as well as its management strategy and simulator functionality, describes the items held in the various files required by GISForman+ in a functional way (more technical descriptions of file formats are in the appendix), reviews the simulation reporting outputs, and outlines the simulation creation tutorial.
