Provides video recordings and presentations from the annual Cal-IPC Symposiums (1995-present).

Find recordings from past workshops, trainings, and online Symposia. Land management experts from across California share years of experience and best practices on topics such as prevention, mechanical control, herbicide control, and more. 

The 2025-2030 Strategic Plan outlines a bold vision focused on science-based conservation, empowering land stewards, and advocating for strong public policies to stop the spread of invasive plants. Provides a plan summary overview, as well as the full report for a detailed breakdown of their proposed steps to achieve this vision.

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.

CalWeedMapper is a new Web site for mapping invasive plant spread and planning regional management. Users generate a report for their region that synthesizes information into three types of strategic opportunities: surveillance, eradication and containment. Land managers can use these reports to prioritize their invasive plant management, to coordinate at the landscape level (county or larger) and to justify funding requests. For some species, CalWeedMapper also provides maps of suitable range that show where a plant might be able to grow in the future. The system was developed by the California Invasive Plant Council and is designed to stay current by allowing users to edit data.

The Canadian Council on Invasive Species (CCIS) serves as a national voice and hub to protect Canada from the impacts of invasive species. With members and chapters from all corners of Canada, along with governments and businesses, the CCIS brings people together to build practical solutions to prevent the spread of invasive species.

In 2010, Oregon, Washington, and Idaho launched a tri-state outreach campaign to inform the public about the dangers of moving firewood to Pacific Northwest forests. The campaign, funded by the United States Department of Agriculture, closely followed the messaging of the national Don't Move Firewood campaign, which recommends buy firewood that was cut locally, preferably within the county or region of where it will be burned. The tri-state outreach campaign, Buy It Where You Burn It, encouraged good campfire practices with branded posters, billboards, and playing cards located at rest stops and state parks.

Early detection and rapid response (EDRR) is a key tenet of invasive species management, where “detection” is the process of observing and documenting an invasive species, and “response” is the process of reacting to the detection once the organism has been authoritatively identified and response options have been assessed.

The NISC FY 2020 - FY 2022 Work Plans identified priority activities in the area of rapid response, including:

• Rapid Response – Tools and Lessons Learned: Support national level rapid response efforts by documenting tools and lessons learned. NISC White Paper (Oct 2022) -- Rapid Response to Invasive Species: Federal Agency Roles [PDF, 577 KB]
• Rapid Response Fund - Criteria and Considerations: Increase resource streams for rapid response to new detections of invasive species. NISC White Paper (May 2022) -- Federal Invasive Species Rapid Response Fund:  Criteria and Considerations for Establishment [PDF, 823 KB]

Environmental DNA is developing into a powerful tool for improving the monitoring and detection of invasive species, which may be present in low numbers and therefore difficult to find. There are a wide range of ongoing efforts by federal and non-federal groups working to improve and apply eDNA to invasive species monitoring and management.

The NISC FY2020 to FY2022 Work Plans incorporated interagency work on eDNA, including the following outputs:
