Invasive species are a global issue and information must move rapidly between researchers, government agencies, and managers for effective prevention and response.

Through collaboration with several California Node partners, the California Regional Invasive Species Information System (CRISIS) represents an effort to develop an improved information management framework for invasive species data. The goal is to develop methods to share data across the Internet for combination into new information products.

Key elements of CRISIS include:

• CRISISCat, a catalog of invasive species resources in California
• CRISIS Maps, an interactive weed mapping and data access system
• The California Weed Mapping Handbook a training resource for local groups involved in wildland weed mapping.

Additional important invasive species resources for California are listed below:

California Invasive Plant Council Cal-IPC's mission is to protect California wildlands from invasive plants through restoration, research and education.
