To support field identification of early detection species, Cal-IPC has designed ID cards for EDRR that can be downloaded, printed double-sided, and trimmed to size. (Lamination increases their longevity.) (The first two cards listed are a glossary of terms and contacts for reporting finds; these cards are designed to go with any set of weed ID cards to form an EDRR guide.) You can also access cards from each species’ listing in our online Inventory.
