Ten projects across government, infrastructure, energy, and conservation — spanning spatial strategy, corridor modelling, ecological assessment, platform development, and network optimisation.
These case studies span the past five years of geospatial and ecological consulting work, delivered across government, infrastructure, and conservation sectors. A number were completed in a technical lead capacity before BioGeo was established — all reflect the rigour, methodology, and hands-on senior delivery that defines how BioGeo works today.
Indicative least-cost route between a major gas pipeline offtake and an industrial development area, to support early-stage cost estimation. Built a multi-criteria cost surface across a broad corridor from five weighted themes (environment, terrain, hydrology, tenure, and regional planning) plus non-weighted hard, prohibitive, and strong-avoidance tiers, run through Distance Accumulation and Optimal Path in ArcGIS Pro Spatial Analyst. Rather than commit to a single weighting prematurely, trialled two scenarios — ecology-led and directness-led — presented side by side for comparison.
Principal consultant and lead geospatial and report author. Designed and implemented a full MCDA framework across a large state development area to identify developable land opportunities for industrial development. Four weighted sub-models (physical, technical, ecological, and planning) were applied across the study area. The Locate Regions algorithm was run across 93 configurations varying background model, area threshold, and region count — demonstrating that the priority locations are consistent across all variants and reflect genuine underlying spatial patterns, not modelling artefacts.
Delivered a regional wildlife connectivity assessment for the Scenic Rim landscape, south east Queensland, covering six focal species: Koala, Greater Glider, Squirrel Glider, Spotted-tailed Quoll, Brush-tailed Rock-wallaby and Grey-crowned Babbler. Built habitat suitability and resistance surfaces per species from regional ecosystem, terrain, canopy cover and hydrology data, defined core habitat patches, then modelled least-cost corridors (Linkage Mapper) and circuit-theory pinch points (Circuitscape) across a 5 km buffered modelling extent to eliminate boundary-truncation artefacts at the edge of the study area. Identified and corrected a genuine data gap where the buffer crossed the Queensland/New South Wales border before finalising results, with every data pull, derivation and modelling decision logged in a dated audit trail.
Three separate engagements spanning six years to optimise the logistical deployment of sampling and servicing teams — with dual objectives of cost reduction and mitigating driving-related safety risk identified as a significant operational concern. Applied advanced network analysis algorithms solving the travelling salesman problem, modelling real operational constraints including maximum field time, workday duration, hub locations, and team configurations. Updated and refined across three engagements as the network and resource configurations evolved.
Habitat suitability and landscape connectivity assessment for koala and greater glider (both listed as threatened under state and Commonwealth legislation) to inform a mine expansion and associated works. Developed species-specific sub-models integrating vegetation type, regional ecosystem mapping, water proximity, and occurrence records, combined using weighted overlay. Applied an integrated analytical framework — least-cost modelling, Linkage Mapper network analysis, and Circuitscape circuit theory — to identify corridor probability surfaces, pinch points, alternative pathways, and priority restoration zones for each species.
Designed, built, and managed a bespoke web GIS platform with integrated mobile data capture, replacing a paper-based field process across a national gas pipeline network spanning thousands of kilometres — including remote areas with no connectivity. Delivered offline data capture (auto-syncing on reconnection), automated alerts for significant species detections, live field team GPS tracking, automated species identification logging with photographs, KPI dashboards across pipeline sections and date ranges, and automated compliance reporting outputs. Handled all requirements gathering, architecture, development, and deployment.
Technical lead for multi-species ecological assessment supporting highway bypass route selection in an ecologically sensitive region. Applied MaxEnt ecological niche modelling at continental scale for all 17 threatened species, refined at regional scale through weighted MCDA integrating vegetation, regional ecosystems, bioclimatic variables, and disturbance factors. Developed ecological resistance surfaces and applied Circuitscape to identify corridor bottlenecks and constrained linkages not captured by single-path analysis — producing a composite ecological cost comparison across all alternative bypass alignments.
Habitat suitability and connectivity model for the threatened brush-tailed rock-wallaby, commissioned to support active conservation planning. Developed sub-models incorporating vegetation type and condition, terrain roughness (proxy for predator refugia), aspect, slope, proximity to water, and species occurrence records — combined via weighted overlay. Converted the suitability surface to an ecological resistance layer and applied least-cost corridor modelling to identify core habitat patches, stepping-stone areas, primary corridors, barriers, and pinch points. Translated outputs into practical conservation recommendations.
A selection of cartographic outputs — geology maps, MaxEnt model visualisations, corridor maps, suitability models, terrain analysis, and web mapping applications.
