Mount Lindesay Highway Upgrade: Ecological Assessment

E2M was commissioned to undertake an ecological assessment, including targeted threatened fauna and flora surveys, for the proposed 3.8 km highway upgrade. Ecological assessments were required as part of the Terms of Reference for the Project, issued by the Queensland Department of Transport and Main Roads.

Challenges

The proposed upgrade traversed two riparian corridors connecting adjacent areas of habitat for a number of threatened fauna, including the koala, tusked frog and spot-tailed quoll. In addition to the ecological assessment, E2M was tasked to provide recommendations on possible fauna sensitive infrastructure in order to minimise potential impacts to movement corridors for local fauna assemblages.

Customised data entry forms loaded onto the latest Trimble GPS devices enabled easy data collection and processing across multiple surveys events.

Outcomes

During the detailed design of the Project, E2M was able to provide recommendations for the installation of fauna friendly infrastructure and exclusion fencing to ensure connectivity values associated with the riparian corridors are maintained as well as minimise fauna-traffic interactions. Implementation of alternative survey methods (e.g. bioacoustics recorders, remote cameras) also provided a cost-effective method to survey for threatened species across different seasonal conditions while adhering to budgetary constraints and project timeframes.
