The Great Lakes and St. Lawrence Governors and Premiers have identified the "least wanted" aquatic invasive species (AIS) that present an imminent threat to the Great Lakes-St. Lawrence River region. In 2013, the Governors and Premiers committed to take priority action on the transfer of these species to and within the region. Since then, the states and provinces have taken more than 50 separate actions to restrict these high-risk AIS, and the US federal government has similarly restricted four of the species.

New research by the Threatened Species Recovery Hub has shown that invasive or pest species are a problem for 1,257 threatened species in Australia, or about four out of five species. The research which has been published in the scientific journal Pacific Conservation Biology also identified the top ten invasive species based on how many threatened species they impact. Lead researcher Stephen Kearney from the University of Queensland said many people may be surprised at which species top the list. “Rabbits, a plant root disease and feral pigs are the top three pest species impacting Australia’s threatened species,” Mr Kearney said.
