Roads fragment quoll territory and concentrate mortality at predictable points: ridgelines, creek crossings, and the edges of remnant bush. A quoll crossing a sealed road at night is, statistically, a quoll at considerable risk.

Quoll Crossing Bridges
Quoll Crossing Bridges puts engineered fauna infrastructure on roads where quolls are killed in numbers.
We build two things. Rope bridges span the carriageway canopy-to-canopy for animals that prefer to travel above ground. Box underpasses run beneath it, furnished with logs, rock and a dry ledge so a quoll will actually use one rather than detour around it. Both designs were developed with the Tasmanian Department of State Growth.
Eleven crossings are installed and monitored with camera traps. The data is unglamorous and essential: we count crossings, we count refusals, and we adjust the next build accordingly.
