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.

A regulation was adopted in 2014 that prohibits or regulates the possession, transport, importation, sale, purchase and introduction of select invasive species. The purpose of this regulation is to help control invasive species, a form of biological pollution, by reducing the introduction of new and spread of existing populations.
Invasive species on the watch list have been identified as posing an immediate or potential threat to Michigan's economy, environment or human health.
