Tracking Wildlife Movements Across Major Highways in Australia

With more and more people on the road nowadays, the number of highways across Australia and the world is increasing. Road underpasses serve not only as a water drainage system, but also as passageways for various wild animals. In addition, rope bridges and “gliding poles” have been built to allow animals such as possums and gliders to come above the highways.

Trovan has supplied fixed reading systems to monitor microchipped animals using these structures. The rope bridges have been fitted with TROVAN flat panel multi-coil ANT-612 antennas connected to LID-650 decoders. These may also be linked to optical sensors and infrared cameras to identify non-microchipped animals. Solar power back-up systems are used to maximize battery life and the intervals between site visits to download data.

The road underpasses present challenges largely in part to their differing dimensions. Custom-sized antennas supplied by Trovan are built to fit numerous different underpasses in Australia, thus allowing various wildlife to pass through, and supply movement data to researchers.

One project conducted by the University of Western Australia involved the supply of ANTSQR-500 (500mm x 500mm square) antennas attached to LID-650 decoders.
