The nutria (Myocastor coypus), a large, semi-aquatic rodent native to South America, was originally brought to the United States in 1889 for its fur. When the nutria fur market collapsed in the 1940s, thousands of nutria escaped or were released into the wild by ranchers who could no longer afford to feed and house them. While nutria devour weeds and overabundant vegetation, they also destroy native aquatic vegetation, crops, and wetland areas. Recognized in the United States as an invasive wildlife species, nutria have been found in at least 20 States and most recently in California. The nutria’s relatively high reproductive rate, combined with a lack of population controls, helped the species to spread.
