Invasive annual grass state-transition simulation models, parameters, input data, and simulation results for Region 3 (Wyoming), USA (2022-2042)
These data are spatially explicit state-and-transition simulation models (STSM) of invasive annual grass (IAG) vegetation dynamics for Region 3, containing datasets for model extents 3A (northcentral Wyoming) and 3B (southwest Wyoming/northeast Utah). The STSM was built using to simulate and track IAG growth and spread as well as response to management actions. Spatially explicit models were built as paired model extents (A/B) for five regions that differed in underlying site conditions, susceptibility to invasion, and the amounts of IAG cover present (seedbank, <8% cover, 8-15% cover, 15-50% cover, >50% cover, uninvaded), representing a range of simulated IAG outcomes across the sagebrush biome. Two scenarios representing alternative IAG management strategies were simulated for each model landscape. Management actions and treatment effort levels were based on historic treatment area polygon data for IAG management, represented treating approximately 1% of IAG infested areas of a landscape, and emphasized allocating treatment actions at a higher rate to areas with more IAG cover.
