Nutria consume marsh vegetation. The nutria is a large, semi-aquatic rodent native to South America. They were brought to the United States in the late 1800s for the fur trade. In addition to damaging vegetation and crops, nutria destroy the banks of ditches, lakes, and other water bodies. The long term damage nutria cause to marsh vegetation subsequently affects the plant and animal species that also inhabit those areas.
