Welcome to the

HexSim Project

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.

Example uses:

Develop PVA models

Impose stressor interactions

Evaluate landscape connectivity

Conduct source-sink analyses

Model competition and predation

Explore landscape genetics

Simulate disease dynamics
