10 Dean Paini 2011 Using likelihood of arrival and establishment to assess the world threat of invasive species - Final Report 21 <p>There are hundreds, perhaps thousands, of invasive species that have the potential to arrive and establish in any particular region or country. Identifying which species are more likely than others to arrive and establish is extremely difficult, yet the capacity to do so is vitally important to the biosecurity of a nation.</p> <p>The aim of this project was to combine arrival likelihood with establishment likelihood to generate the invasion threat to Australia for 1,486 invasive fungal pathogens and insect pests, from all countries of the world.</p>
