California Invasive Plant Inventory
California Invasive Plant Council.
This interactive database contains information on the plants currently included in the Cal-IPC Invasive Plant Inventory. The Inventory categorizes plants as High, Moderate, or Limited, reflecting the level of each species' negative ecological impact in California. Includes options to search for species by region and by habitat type. The database provides a better view of information on each species and allows users to download the entire Inventory as a spreadsheet.

Invasive Species Regulations: Regulated and Prohibited Invasive Species
New York Department of Environmental Conservation.

Minnesota's Top 124 Terrestrial Invasive Plants and Pests
University of Minnesota. Minnesota Invasive Terrestrial Plants and Pests Center.
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
