ST-Sim version 1.5 is now available for download at There are a number of important new features in this version including:

  1. Significant changes to the transition spread algorithm to allow for stochasticity in the shape of transition events
  2. Transition direction multipliers which allow spread direction to influence the rate of spread of transitions for simulating processes such as the influence of wind on fire.
  3. Transition slope multipliers to allow for topographic influences on transition spread.
  4. Transition adjacency multipliers to allow for the neighborhood of a cell to influence it’s transition probability.
  5. The ability to graph proportions of the landscape in specified state classes and undergoing transitions.
  6. An ecological departure plugin.
  7. Transition average annual probability summary raster output for spatial simulations.
