Attendees at the International Association of Landscape Ecology (IALE) North America Meeting in Toronto will have the opportunity to participate in a hands-on SyncroSim and ST-Sim Workshop on Tuesday, May 12, from 1:00 pm to 5:00 pm. SyncroSim is a free software platform designed to streamline data management tasks associated with ecological forecasting, in order to facilitate scenario and uncertainty analyses. SyncroSim allows modelers to develop “packages” to bundle and share collections of linked GitHub-based model scripts. One such package has been developed for a model called ST-Sim. ST-Sim uses a state-and-transition simulation model approach to forecast landscape dynamics, including projecting changes in both vegetation and land use. This half day workshop will introduce developing and running spatially explicit models of landscape change using the open-source ST-Sim package within SyncroSim. The workshop will also introduce developing custom packages in SyncroSim, including packages to extend the core functionality of ST-Sim. Workshop registration opens in February.
