Council or Task Force

Database: California Invasive Plant Inventory
Host: California Invasive Plant Council (Cal-IPC)
Scope: This interactive database has been updated (Mar 2013) and 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.

Note: The invasive species ranks (I-Ranks) are on the Status tab. Use the link at the top of the Status tab that says "U.S. Invasive Species Impact Rank (I-RANK)" or just scroll down the page until you see the I-Rank select criteria. You can search for individual species by name, by location or search by the overall invasive impact rank.
