To determine which pests posed immediate threats, MITPPC undertook an expansive evaluation process. It convened 15 expert panelists, who ultimately identified 124 significant invasive species threatening our state. This panel also identified 17 criteria that could be used to rate species in an objective, computerized ranking system. Criteria included factors like environmental and economic impact, ability to establish and spread and proximity to the state. Rankings are updated regularly, no later than every other year or as new threats emerge on a more urgent basis. The full whitepaper, "Minnesota's Top 124 Terrestrial Invasive Plants and Pests: Priorities for Research (PDF | 1.4 MB)," outlines all prioritization methods and results

Crippled plant industries, trade suspensions and a devastated environment—Australia's Top 40 National Priority Plant Pests have damaging potential, from vine-attacking bacteria to a giant snail. The Top 40 pests were recently endorsed by Plant Health Committee, Australia's top committee for plant biosecurity. They were identified through a national expert elicitation process, which considered the economic, social and environment threats the pests posed to Australia. For more information see Australia's National Priority Plant Pests.
