A new zone was created for the SIMulating Patterns and Processes at Landscape scaLEs (SIMPPLLE) model for vegetation simulations in the hydrologic Great Basin. Current parameterization is designed to use LANDFIRE data as input. Three separate mountain areas were considered for this study: the Clover Mtns., the Sheep Range, and the Snake Range. Fire histories for each area were based on an eleven year period (1986-1996), and were acquired from the National Fire Occurrence database. Ten-year calibration simulations were performed for each mountain area using 1999 vegetation data to initialize the run. Vegetation data from 2008 was used to assess the simulated end states. Model pathways were adapted to the Great Basin ecosystems, successional stages, disturbance processes, and ecoclimatic features. The model performed well at predicting vegetation type, but was inconsistent predicting canopy cover density and canopy height.
