Abstract
Presented on Wednesday 18 May: Session 15
Biosecurity tools are a key aspect of an effective biosecurity system, however, existing surveillance and monitoring programs are often expensive, resource intense, reliant on special expertise, long-term and deliver variable results. Advances in innovation and technology provide opportunity to improve program efficiency, reliability and cost-effectiveness. Chevron Australia developed and deployed tools to help monitor and identify non-indigenous species on Barrow Island, a Class A Nature Reserve and home to the Gorgon Natural Gas Project, operated by Chevron Australia and a joint venture of the Australian subsidiaries of Chevron (47.3%), ExxonMobil (25%), Shell (25%), Osaka Gas (1.25%), Tokyo Gas (1%) and JERA (0.417%). Tools include: The PAWS® (Print Acquisition for Wildlife Sensors) pest identification sensor pad and PAWS® live capture devices for rodent detection and monitoring, EARS (Environmental Acoustic Recognition Sensor) devices that record the male Asian house gecko’s call and can be adapted to incorporate other species if required, LAMP (Loop Mediated Isothermal Amplification) assay to identify Asian house gecko scats or tissue samples with an in situ molecular tool, Gecko identification application (app) enabling the workforce to participate in citizen science programs. These technological advances have helped to improve surveillance and biosecurity programs on Barrow Island, realising benefits including: longer monitoring periods for lower costs, resulting in greater confidence in surveillance outcomes, in situ diagnostics providing more rapid identification to enact an immediate response; deployment of live capture devices, reducing non-target captures (consequently, a more ethical tool); wider workforce participation. While these innovative tools target species likely to threaten Barrow Island’s unique biodiversity, the technology can be adapted for other environmental monitoring programs.
