Operational Activities: Nutria

Last Modified: May 27, 2025

Nutria ( Myocastor coypus) are large, semi-aquatic rodents that are native to South America. The species is invasive in the United States and established in 17 States. 

Nutria cause extensive damage to wetlands, agricultural crops, and structural foundations such as dikes and roads. They may also threaten human health and safety and serve as a reservoir for tularemia and other diseases. Integrated management solutions to nutria problems may include habitat manipulation, population management, and innovative approaches and tools generated by research.
