We model landscape connectivity using spatially explicit networks and circuit theory.

Current work maps old-forest connectivity with Omniscape to inform biodiversity management in the Quesnel Natural Resource District, British Columbia, for Phase 3 of the Connectivity, Corridors, and Functional Ecological Networks (C-C-FEN) project.

The grainscape R package builds spatially explicit networks from minimum planar graphs, finds corridors, and scales networks across grains of connectivity. Outputs work with igraph for network analysis and can be exported to GIS software.

Authors
Ecologist and simulation modeller

Dr. Chubaty is an ecologist and simulation modeller who builds spatial models of forest landscapes and the species that live in them. He completed his PhD at Simon Fraser University modelling host selection in mountain pine beetle (MPB), followed by postdoctoral research at Université Laval and Natural Resources Canada developing forecasting models of MPB spread.

He runs FOR-CAST Research & Analytics in Calgary, Canada. His recent work includes LANDIS-II forest landscape simulation studies, landscape connectivity modelling, and analyses of insect outbreak dynamics, to inform land management and species-at-risk decisions. He writes open-source R packages for this work, including grainscape for connectivity analysis, landisutils for LANDIS-II simulations, and co-developed the SpaDES simulation platform. He advocates for open data and reproducible workflows.
