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:
- Cape Ivy Biocontrol Research
- The International Broom Initiative
Saharan mustard - Background information and presentations on control strategies for Saharan mustard (Brassica tournefortii).

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.
