HexSim is a free, versatile, multi-species, life history simulator ideal for building models of animal and plant population viability, interactions, and responses to disturbance.  HexSim models are spatially-explicit and individual-based, and HexSim individuals can be assigned dynamic life history traits.  HexSim also includes a full genetics sub-model, making it a true eco-evo simulator.

HexSim is not licensed, and is available free of charge.
