NAISMA: Decades-Long Partnership Successfully Eradicates Destructive Nutria Rodents from Maryland -
November 15, 2023 @ 1:00 pm – 2:00 pm CST
Nutria are invasive, semi-aquatic, South American rodents first released into Dorchester County, Maryland in 1943. Since their release, nutria have destroyed thousands of acres of wetlands through their destructive feeding habitats. A concerted effort to eradicate nutria in Maryland began in 2002 following a two-year pilot project to determine if nutria could be eradicated from the Chesapeake Bay and if the damaged marshlands would recover.
The Chesapeake Bay Nutria Eradication Project began the first phases of the project in April 2002. Twenty years later in 2022, The Chesapeake Bay Nutria Eradication Project announced that nutria were successfully eradicated from the state of Maryland.
