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.

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.
