• Spatially explicit, patterns of vegetation can influence the probability and
spread of disturbance processes across the landscape
• It’s total design includes landscape components of vegetation, land units,
aquatic units, and man-made units.
• Functional across a range of scales from thousands to millions of acres
• Provides a continuity in planning tools for strategic to tactical planning.
• Designed to work with existing inventory data in polygon or grid format.
• ArcView and ArcGIS extensions have been developed for spatial output
• Stochastic disturbance processes. Probabilities are computed for each individual
community in a landscape.
• Landscape simulations can start with a history of disturbance activities and
locking in current disturbance events from insect detection surveys.
• History of each vegetation unit development (treatments, insects or fire)
makes a difference in its response to disturbances.
• Schedules treatments which can be linked to changing vegetation attributes
and disturbance process occurrence.
• Links to other scheduling and optimization models such as MAGIS and
• SIMPPLLE operates on any computer system that supports a Java virtual
• Regional Climate changes and its relationship to fire suppression, insect
occurrence and intensity can be incorporated into simulations
