Model movement and connectivity across landscapesCircuitscape is an open-source program for modeling ecological connectivity across heterogeneous landscapes. Using algorithms from electronic circuit theory, it predicts patterns of movement, gene flow, and genetic differentiation among plant and animal populations. Unlike a least-cost path approach that emphasizes one route, it evaluates the combined effects of multiple possible pathways. Researchers and conservation practitioners can use its results to investigate connectivity, barriers, and potential movement corridors.

Circuitscape for Windows 10 - Full description
Circuitscape is an open-source program for studying ecological connectivity across heterogeneous landscapes. It applies algorithms from electronic circuit theory to model how organisms, genes, or other forms of biological movement may spread between populations. It is intended for researchers and conservation practitioners who need to assess connections across a landscape where movement is affected by varying conditions.
The program represents a landscape as a network of pathways with differing resistance to movement. In the circuit analogy, low-resistance areas provide easier routes, while high-resistance areas impede movement. Rather than selecting only a single least-cost route, Circuitscape considers the effects of many possible pathways at the same time. This can reveal how movement may be distributed across a landscape, including areas where multiple routes converge or where connectivity depends on a narrow set of passages.
Researchers can use the resulting predictions to examine potential movement patterns, gene flow, and genetic differentiation among plant or animal populations. Comparing modeled connectivity with landscape conditions can help identify areas that may support movement, barriers that may isolate populations, and locations where preserving or restoring habitat could matter. Results depend on how the landscape and its resistance values are represented, so the model is best used alongside appropriate ecological data and expert interpretation.
Circuitscape complements least-cost path analysis by accounting for alternative routes instead of reducing connectivity to the single cheapest path. This makes it useful when movement is expected to occur through several viable routes or when the combined influence of pathways is important. It can support landscape-scale research and conservation planning, but its predictions are analytical estimates rather than direct observations of animal movement or gene exchange.
Circuitscape is free and open source. It is available for Windows, macOS, and Linux; the Windows compatibility information includes Windows 10. Its focus is specialized connectivity analysis rather than general-purpose mapping, and users need suitable landscape data and a model of how environmental features affect movement.
