Habitat and species distribution models

Where a species is likely to be, from expert criteria or from its records.

Relief map of long-nosed potoroo habitat suitability from Woodford to the border ranges — Long-nosed potorooHabitat from ecological criteria alone, from Woodford to the border ranges. Darker blue is better habitat.

Land planning

Multi-criteria models that rank land, for development or for conservation.

Road segment risk maps showing maximum and mean risk scores — Road upgrade riskA graded risk surface from elevation, flood extent, drainage, land use and tenure, used to prioritise road upgrades.

Routing

Least-cost routes for linear infrastructure, and route optimisation.
