Roy Hill Culverts Fauna Research & Advice
Roy Hill selected Ecoscape to design, implement and report on a research program to assess the success of installed culverts under linear rail infrastructure as a means to measure impact to fauna species. The research project used a robust experimental design that was replicated in order to statistically test the impact of linear infrastructure on culvert preference of fauna species, fauna use of culverts and ecological connectivity. The research program is currently still underway with two years of data already collated for the three year monitoring program.
The research program used an array of trail cameras installed at a range of culvert sizes in three fauna habitat types along the 334 km rail line between Port Hedland and the Roy Hill mine. Cameras were deployed for two 10 week periods in a calendar year to detect species over seasonal change. Species presence data at culverts was collated and converted to a use index to determine culvert size preference and compared with data from cameras deployed in adjacent habitat to confirm species presence.
The project is being conducted to address Commonwealth environmental approvals conditions and provides a unique view on the impact of rail infrastructure on fauna movement in the Pilbara region.
