Summary

Abstract: The range and variation of historical landscape dynamics provide a reference for designing ecosystem restoration and fuel hazard reduction treatments on today's landscapes. Simulation modeling is a vehicle that can be used to estimate the range of conditions experienced on historical landscapes. LANDSUMv4 (Landscape Succession Model version 4.0) is a tool for simulating historical range and variation (HRV) of landscape characteristics. The model simulates fire and succession on fine-scale landscapes for land management applications. It simulates vegetation development or succession as a deterministic process by changing the species composition and stand structure assigned to a polygon. Disturbance initiation is modeled stochastically and disturbance effects are based on the current vegetation conditions of the polygon. In simulations, fire is spread across landscapes using simplistic slope and wind vectors. The model has been extensively tested and an intensive sensitivity analysis was performed on all input parameters.
