Cal-IPC works to disseminate information on invasive plant impacts and control to land managers, volunteer groups, and others conducting on-the-ground restoration and management activities. This page links to projects and information of interest to land managers.

The Invasive Plant Inventory (aka "The Weed List"): Cal-IPC is reviewing information on approximately 300 of the invasive plants in California to rank them by statewide impacts. This project is an update and expansion of the 1999 list, "Exotic Pest Plants of Greatest Ecological Concern in California." Completed Plant Assessment Forms provide data and documentation on the impacts, invasiveness, and extent of these invasive plants.

The Weed Workers' Handbook - Published in conjunction with the Watershed Project, this manual provides information on control techniques for common invasive plants in the San Francisco Bay Area. A pdf version is available at the link above.

Other publications: Cal-IPC has several books on invasive plant identification and management available, as well as brochures suitable for a general audience.

Policy information: Information on pending and recently passed state or federal legislation on invasive species.
