This section includes:
- Inventory Background and Overview - Includes definitions, criteria, uses, summary, references and more
- The Interactive Inventory Database - Allows you to sort invasive plants by name, rating, alert status, or scores in particular sections You can also arrange plants based on geographic distribution and see the full Plant Assessment Form for each plant.

This section includes information about invasive plant control methods, as well as:
Research
This section includes:
- Research Assessment - A group working to create an outline of known information and research gaps.
- Biological Controls - Also know as biocontrol agents, these are insects or pathogens imported from an invasive plant's home range in order to control the plant in its invasive range. Cal-IPC engages in two specific biocontrol projects:
- Saharan mustard - Background information and presentations on control strategies for Saharan mustard (Brassica tournefortii).
Mapping
This section includes:
- Statewide Risk Mapping - Cal-IPC works with local Weed Management Areas to compile distribution data, and compares this with maps we generate for suitable range based on climatic parameters to determine potential spread.
- Arundo Mapping - Cal-IPC has created high-resolution maps of Arundo donax distribution in southern California coastal watersheds.
