Field ID Guides/Cards on Invasive Species

 Identification cards are designed to be used for identifying invasive species in the field. They are usually smaller than 8 in. X 11 in. to make them easier to use. Some websites have cards you can order or pdf versions you can download directly. Most of the cards listed here are free to download and print. You can cover them with a water proof laminate or a clear plastic sleeve (a small photograph book would work) to make them more user friendly in the field.
