Cal-IPC works with partnering organizations to create science-based solutions that will control wildland weeds. Peruse helpful links below to see how your Cal-IPC membership is making a difference in California.

Invasive Plant Management & Early Detection and Rapid Response (EDRR)

Visit this section to find a range of tools and references for land managers to help battle invasive plants.

Weed Management Areas (WMAs) and Regional Partnerships

California’s Weed Management Areas (WMA) have proven to be an effective instrument for controlling the spread of invasive weeds. Learn more about this collaborative effort. Find information on the background of WMAs here.

Invasive Plant Mapping & Prioritization

Cal-IPC supports a range of mapping tools, providing a foundation for strategic management and monitoring. Through effective mapping, we can keep an eye on known problems, and detect new threats.


Preventing the introduction of invasive plants is the most cost-effective way of protecting our wildlands. Find links to Best Management Practices for Land Managers and for Transportation and Utility Corridors, as well as training videos, and more.

Climate Adaptation

A changing climate creates new challenges and new opportunities for controlling the spread of invasive plants in our state. Find links to several resources to help land natural resources managers address these challenges.


Cal-IPC develops and supports public policy initiatives at the state and national levels to help control the spread of invasive plants. Read more about these efforts.

Invasive Plant Research

Research is at the heart of Cal-IPC’s work, keeping our data accurate with input from on-the-ground observations. Read more about how Cal-IPC coordinates these efforts.

Awareness Campaigns

Cal-IPC partners with several organizations to promote awareness campaigns. From landscaping, to firewood, to pet care – there are many ways we can help to control the spread of invasive species.
