Incursions of invasive exotic vertebrate pests need to be detected early for there to be any chance of cost-effective containment and eradication. With the diverse array of exotic species of concern and the wide array of possible introduction points, there is insufficient public funding available for structured, human-based, agency delivered surveillance to meet this need. However, advances in sensor and genetic sampling technology may enable more cost-effective surveillance by industry and government, and harnessing the observational powers of community surveillance activities can potentially increase the scale and sensitivity of surveillance efforts dramatically.
There has been little evaluation of vertebrate pest biosecurity information content of community surveillance data streams, and how they could contribute to the timely detection of incursions of invasive exotic vertebrates into Australia. The aim of this research will be guidelines for how to best combine passive and active surveillance tools with community surveillance in a complementary manner to enable the timely detection of invasive vertebrates and hence prevent the establishment of further vertebrate pests.
The broad research objective is to develop a coherent, complementary surveillance approach for combining community surveillance and targeted surveillance using passive and active sensing technologies to detect and manage vertebrate pest incursions in a timely manner.
August 2019 update:
A survey of primary industry, conservation and NGO organisations identified high-priority established and non-established vertebrate pests. From this, a list was developed of high-priority vertebrate pests for which acoustic surveillance is considered applicable. Preliminary lists identified 54 priority invasive species, with 28 identified by more than one state as a priority.
A newly-employed data technician will improve data handling procedures and assess data entered into the Atlas of Living Australia (ALA) website. Community reporting rates for cane toads, red-eared slider turtles and common starlings to ALA will be assessed. Community reporting lines not captured within the ALA will also be identified and assessed.
Acoustic surveillance units are being procured for the collection of reference calls for Asian black-spined toads and Indian house crows in Singapore. Commercialised acoustic traps for cane toads ‘Toadinator®’ (Animal Control Technologies (Australia) Pty Ltd) have been modified to play Asian black-spined toad audio, eight traps will be deployed in high risk sites around Brisbane. A local community group will be engaged to help deploy and monitor these traps.
