California Invasive Plant Inventory database

The California Invasive Plant Inventory (CIPI) is a comprehensive database that tracks plant species in California known to be invasive—that is, plants that spread aggressively, disrupt local ecosystems, and threaten native plants and animals. Managed by a conservation organization, it provides detailed information about these species, helping land managers, scientists, and policymakers make informed decisions to prevent their spread and protect California’s biodiversity. The database supports efforts to monitor, control, and reduce the impact of invasive plants across the state.
