Indiana's "Most Unwanted" Invasive Plant Pests


The "Most Unwanted" Invasive Plant Pests are compiled by the Indiana Cooperative Agricultural Pest Survey (CAPS) Committee. There are lists for insects, mollusks, nematodes, pathogens, and plants. The lists identify exotic and/or invasive species, pests regulated by state or federal laws, and pests that may or may not be present in Indiana. These species have the potential to threaten cultivated and natural plant communities.  The plant list is slightly modified from the Official Indiana Invasive Species Council Invasive Plant List:

The term 'exotic species' is a geographical attribute, meaning an organism that is found outside of its historic range. Synonyms for exotic species are non-native, nonindigenous, and alien. An exotic species may or may not be invasive.

The term 'invasive species' is a biological attribute, meaning that the species can establish itself and out-compete other species, usually severely disrupting the stability of the affected ecosystem. It may or may not be exotic.
