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.
