The Chesapeake Bay Nutria Eradication Project (CBNEP) announced at an event at Blackwater National Wildlife Refuge today that Maryland is now free of the exotic, invasive nutria. The U.S. Fish and Wildlife Service (USFWS), U.S. Department of Agriculture’s Wildlife Services (WS), and Maryland Department of Natural Resources (DNR) have worked more than 20 years to make this difficult task -- never accomplished before on this scale -- a success.

Landowners, we need your help: CDFW has deployed nutria survey teams from the Delta through the San Joaquin Valley and needs written access permissions to enter or cross private properties for the purposes of conducting nutria surveys and, where detected, implementing trapping efforts. Landowners and tenants, see Nutria: The Triple Threat to California's Future [PDF, 598 KB]; so CDFW can survey for and remove destructive nutria from your properties, complete and submit the Nutria Project Temporary Entry Permit [PDF, 207 KB].

The Chesapeake Bay Nutria Eradication Project (CBNEP) historically used working dogs to locate invasive nutria populations across the Delmarva Peninsula. As nutria populations decreased, the transition to detection and detector dogs was necessary. Dogs can be trained to smell the evidence of specific animals and plants in an area without visual identification.

Maryland’s eastern shore has seen thousands of acres of protective marshland impacted by the nutria's destructive feeding habits. To protect the valuable resources of Maryland’s Chesapeake Bay, The Chesapeake Bay Nutria Eradication Project (CBNEP) began in 2002 to permanently remove invasive nutria from the marshes of the Delmarva Peninsula and to protect, enhance, and restore the aquatic and river ecosystems they damaged.
