Understanding and intervening in illegal trade in non-native species

Summary

The growth and commercialisation of the open source internet has greatly modified the environment in which pet markets and illegal wildlife traders can operate. Given the complex and cryptic nature of these online networks, the development of advanced web intelligence techniques is core to the successful disentanglement of the trade. As online trade platforms and networks grow, so too does the inadvertent risk of new vertebrate introductions and invasions, as a result of intentional or unintentional release.  

The over-arching goal of our project is to extract and tease apart the great deal of relevant online information that is available, using sophisticated techniques and analytical approaches, in order to assist biosecurity agencies and decision-makers to take early preventative action to protect the environment and economic activities (e.g., agricultural and social assets).

Commenced

Objectives

Our project will develop novel approaches for understanding the nature of exotic pet keeping, illegal vertebrate trade in Australia, and alien species incursions.  

The objectives of the project are to develop efficient surveillance and identification tools for:  

  1. compliance of keeping and trade in alien species and early warning of new alien vertebrate incursions; and 
  2. identifying the origins of seized specimens from illegal keeping and at-large incursions

Outputs

February 2019 update: 

This project has collated two decades of chordate interception records from state and commonwealth reporting agencies.  These data have been interrogated for summary statistics and general trends relating to chordate interceptions in Australia over time. The team has identified pathways and commodities associated with high levels of pre-border chordate interceptions and identified new exotic incursion threats to Australia. 

August 2019 update:

To combat the illegal trade of non-native species, this project is designing, testing and implementing automated web-scraping tools to analyse exotic live animal trade websites in Australia, United States and Europe. One finding of this project over 2018-19 is that trade in live vertebrates in the United States is a robust estimator of preference for alien vertebrates in Australia. Consistent with U.S. trade activity, the project has found, on Australian e-commerce sites, evidence for Illegal trade in non-native reptiles and grey-listed ornamental fish.

Bone and scute samples of Red-eared slider turtles have had preliminary isotopic and ablation laser analyses performed with the results being prepared for publication. A pilot study to determine specimen provenance (captive, wild, international) from analyses of stable isotope ratios has been completed
and submitted for publication.
