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.

The Indiana Terrestrial Plant Rule (312 IAC 18-3-25) designates 44 species of plants as invasive pests. This rule makes it illegal to sell, gift, barter, exchange, distribute, transport, or introduce these plants in the State of Indiana. This rule goes into effect in two stages. As of April 18, 2019, it is illegal to introduce plant species on this list not already found in Indiana. Plant species already in trade will be prohibited from sale one year later (April 18, 2020).
