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.
*Present in Connecticut means listed as occurring in the state by the Flora Novae Angliae by Arthur Haines or a documented occurrence recorded with the Invasive Plant Atlas of New England (IPANE) or the George Safford Torrey Herbarium (CONN) at the University of Connecticut.
