Early Detection & Research Lists

If you find these species: Report your findings to the CT Invasive Plant Coordinator at reportinvasives@uconn.edu.  Aquatic species reports will be forwarded to the Department of Energy and Environmental Protection (DEEP).  Be sure to include as much detail as you are able (attach photographs if possible) and provide your contact information.  You may also report these and other species online at www.EDDMapS.org.  EDDMapS is an online mapping program that can be used to track invasive plants.

 

Invasive and Potentially Invasive Plant Early Detection List

Click here to view handout of CT Invasive Plant Early Detection List (PDF)

Early Detection List: These plants are known to be invasive or potentially  invasive in Connecticut and are on Connecticut’s list of Invasive and Potentially Invasive Plants.  They are known to be present only in relatively low numbers at limited locations in Connecticut. These species should be considered for control and eradication efforts in the state when resources are available.

(P) indicates Potentially Invasive (all others are considered Invasive in Connecticut)

Research List

Research List: This is a list of plants about which more information is desired.  This is not a regulatory list or an invasive plant list.  Plants are not necessarily listed here prior to inclusion on an invasive plant list.  Rather, more information about these plants and their occurrence in the state is desired and current records are limited.

The Invasive Plants Council (IPC) is the body responsible for the Invasive Plant List under CT General Statutes Sec. 22a-381b.  To request a species be examined by the IPC, fill out the “Guidelines for submitting a Candidate Species for Council Review” document available at the bottom of the IPC Criteria for listing page.
