Nutria habitat, in general, is the semiaquatic environment that occurs at the boundary between land and permanent water. At high densities coypu are able to convert marshland to open water by feeding on plants. Nutria can be rather social animals and sometimes live in large colonies, reproducing prolifically. Also known as the Nutria, the Coypu (Myocastor coypus) is a rodent native to the subtropics of South America.
Similar Species: Nutria, also known as coypu or swamp rats, are large rodents that live in areas with lots of freshwater. •American Beaver is larger in size with a large horizontally flattened tail. Their populations in those locations are kept in check by the seasonal drought-flood cycles. Nutria (also called coypu) are varied eaters, most fond of aquatic plants and roots. It is more commonly known as the Nutria or "River Rat.". Nutria are aquatic creatures and prefer freshwater to saltwater. Nutria eat about 25% of their body weight each day in plants and their roots, wreaking havoc on the native ecosystem. Nutria have a voracious appetite for wetland plants and will chow down an entire plant — roots, bark and all, according to Animal Diversity Web. Nutria are native to the marshes and coastal lakes in Bolivia and Southern Brazil, according to Columbia University. These mammals are native to South America and were introduced into the United States between 1899 and 1930 through the fur industry, according to the U.S. As mentioned, nutria will dine on numerous agricultural crops, such as rice, corn, wheat and more. The removal of the root systems destabilizes the soil around the water, which causes it to quickly erode and become open water. Coypu feeding on sea oat rhizomes in Mississippi barrier islands have led to sand dune erosion in these important habitats (GSMFC 2005). Breeding information: Breeding occurs throughout most of the year.
Nutria may inhabit a riverbank or lakeshore, or dwell in the midst of wetlands.
But when the fur market collapsed in the mid 1900s, many nutria farmers couldn't afford to keep their animals and released them into the wild. Nutria are large, web-footed rodents that are more agile in the water than on land. As an herbivore, the Coypu feeds on vegetation and resides in burrows—both of which are found along marshy banks. It can be a significant health hazard for people and animals to drink or swim in water contaminated by nutria feces and urine, according to FWS.
Local Concern: Nutria, sometimes call coypu, are hosts for several pathogens and parasites that can infect people, pets, and livestock. Cattails, reeds, and sedges are favorite foods; they will also eat some grains.

The nutria, known elsewhere as the coypu, was thought to have been eradicated in the 1970s. The furry rodents will occasionally eat small invertebrates such as insects and snails, according to FWS. Continuous monitoring and removal of nutria is especially important as global warming increases the number of potential nutria habitats in North America, according to a 2019 study published in The Journal of Wildlife Management. Habitat destruction caused by coypu threatens rare marshland species of bird, fish and invertebrates. Nutria once lived only in southern South America, but they have been domesticated as fur animals and transplanted around the world. Weight: 15 - 25 pounds. Because nutria are such a prolific and resilient species, controlling their populations to curb further environmental damage is a significant challenge.

Length: 30 - 42 inches But nutria aren't considered picky eaters as they're often caught eating crops such as rice, sugarcane and corn. Their activity can cause such extensive damage that the levees need to be completely reconstructed. Breeding information: Breeding occurs throughout most of the year. All rights reserved. It just takes a single, pregnant female to quickly repopulate an area from which nutria were previously eradicated. Nutria habitat, in general, is the semi-aquatic environment that occurs at the boundary between land and permanent water. Males have a home range of about 14 acres, while females stay even closer to home, keeping within about a 6-acre radius.
