What animals are affected by nutria?
California is the latest region to be plagued by the large, buck-toothed, web-footed rodent. Earlier this month, the state’s fish and wildlife department issued a warning about the influx of nutria. Breeding populations have recently taken hold in the San Joaquin Valley, just east of San Francisco.
How do nutria destroy wetlands?
Nutria burrows can also damage flood control levees that protect low-lying areas; weaken the foundations of reservoir dams, buildings, and roadbeds; and erode the banks of streams, lakes, and ditches. Nutria damage, however, is not limited to burrowing. Depredation on crops is well documented.
How does nutria affect?
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.
Where is the nutria an invasive species?
Today, nutria populations are found across the U.S., primarily in the coastal states, according to FWS. They’re also an invasive species in Europe, Asia and Africa due to fur-farm escapees, according to the Global Invasive Species Database.
How long can a nutria live?
The life span of nutria is approximately 6.5 years in the wild, although the record life span of nutria in captivity is 12 years. Nutria is almost completely nocturnal. They live in burrows that are approximately one meter long.
Can you eat nutria?
Despite looking like a giant rat, wild nutria are clean animals. “My friends and great chefs Daniel Bonnot, Suzanne Spicer and John Besh helped convince a majority of consumers that nutria meat is very high in protein, low in fat and actually healthy to eat.

Observations on state or federal lands should be immediately reported to local agency staff.
What kind of damage does a nutria do?
Nutria construct burrows in banks of rivers, sloughs, and ponds, sometimes causing considerable erosion. Burrowing is a commonly reported damage caused by nutria. Burrows can weaken roadbeds, stream banks, dams, and dikes, which may collapse when the soil is saturated by rain or high water.
How does nutria affect wildlife in the marsh?
Overutilization of emergent marsh plants can damage stands of desirable vegetation used by other wildlife. Nutria are aggressive competitors with the native muskrat which is smaller. Muskrats have been largely eliminated or greatly reduced where nutria have become established.
What kind of environment does a nutria live in?
Nutria prefer living in aquatic environments. They are found most frequently in freshwater marshes and wetlands. They sometimes inhabit brackish waters, and on rare occasions, salt water marshes as well. Distribution of the Nutria Rat
How did the nutria become an invasive species?
The nutria, also known as the “coypu,” is a large, semi-aquatic rodent. The history of the nutria and its spread as an invasive species is relatively unique in nature. Fur Farm Escapees – Nutrias spread from their natural range in South America through the development of fur farms.
