This past nutria season, which generally runs from November to March, around 240 people participated in the nutria harvest, collecting about 223,000 tails worth more than $1.1 million in … Nutria (Myocastor coypus) are almost large rodents that rise to between 17 and 25 inches tall (43 to 64 centimeters) from head to bottom, which is of the sheer size as a raccoon. It just takes a single, pregnant female to quickly repopulate an area from which nutria were previously eradicated.

Whether you’re in unique New York or selling seashells by the seashore, show off your impressive command of diction today.
It has coarse brown outer fur and soft gray under fur, which is called nutria.
In the late 19th and early 20th century, numbers dwindled in the original habitat and fur ranchers brought the species to North America, Europe, Africa, and Asia.
The holiday was created by renowned bundt pan purveyors Nordic Ware to celebrate their 60th anniversary in 2006. Nutria are now considered a nuisance in the U.S. and other parts of the world where their populations have grown and their presence has disrupted the native ecosystem. 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. Also, nutria are typically more destructive in the winter than in the growing season, due largely to the scarcity of above-ground vegetation; as nutria search for food, they dig up root networks and rhizomes for food. Some of those animals either escaped or were released, taking up residence along the Gulf Coast, where they flourished in the swamps and other wetlands. Today, nutria populations are found across the U.S., primarily in the coastal states, according to FWS. Nutria are native to South America, but over the past century or so, they have traveled around the globe. [36][37] They either construct their own burrows, or occupy burrows abandoned by beaver, muskrats, or other animals. A nutria has a white muzzle, white whiskers, and orange teeth.
Interesting Facts About the Nutria Rat. The Oregon Department of Fish and Wildlife has found that excluding nutria from their preferred environments to be the most effective approach. Sandro Bertolino, Aurelio Perrone, and Laura Gola "Effectiveness of coypu control in small Italian wetland areas" Wildlife Society Bulletin Volume 33, Issue 2 (June 2005) pp. [55], Nutria are spreading rapidly in Washington State. Originally, the nutria was native to temperate and subtropical South America. Feral hogs, also known as wild boars (Sus scrofa), swamp rabbits (Sylvilagus aquaticus), and muskrats (Ondatra zibethicus) are less common, but feral hogs are increasing in number in Louisiana wetlands. John Montagu, 4th Earl of Sandwich, was also born around this day (on November 13) in 1718, so feel free to celebrate and eat mightily throughout the month.
Nutria have a voracious appetite for wetland plants and will chow down an entire plant — roots, bark and all, according to Animal Diversity Web. Although they’re about the size of a raccoon, nutria look more like a cross between a small beaver and a giant rat, with two large, orange front teeth and long, rounded tails. Fish and Wildlife Service determined wetlands covered only 5% of the land surface of the contiguous 48 United States, but they support 31% of the nation's plant species.
Nutria is a very lean, protein-rich meat, low in fat and cholesterol with the taste, texture, and appearance of rabbit or dark turkey meat. “But that takes a concerted and sustained effort.”, Related: Swamp Rats & Baby Dolphins!

[58] The problem became so serious that Sheriff Harry Lee of Jefferson Parish used SWAT sharpshooters against the animals.[59]. These animals live in groups that typically consist of two to 13 individuals, according to the University of Michigan Museum of Zoology's Animal Diversity Web. Their undercoat is much more beautiful, and they are often trapped or farmed for their undercoats, which … The coypu (from Spanish coipú, from Mapudungun koypu;[3][4] Myocastor coypus), also known as the nutria,[1][5] is a large, herbivorous,[6] semiaquatic rodent. In Swedish, the animal is known as sumpbäver (marsh/swamp beaver). But nutria aren’t considered picky eaters as they’re often caught eating crops such as rice, sugarcane and corn. They live in burrows connected by tunnels that they dig near rivers, canals, lakes or in wetlands, according to National Geographic.
She has taught science courses at the high school, college, and graduate levels. Their feeding and burrowing opens wetlands to flooding, damages roads and bridges, and destroys crops. The group often includes related adult females, their offspring and a single adult male. Ten were trapped on the Curraheen River in 2017, but the rodents continued to spread, reaching Dublin via the Royal Canal in 2019. Look at the size of that rat!'"

Other potential chemical pesticides would be required by the US Environmental Protection Agency to undergo vigorous testing before they could be acceptable to use on nutria. 162–175. Combined with cold winters in 1962 to 1963, almost 40,500 coypu were removed from the population. It also is expensive to operate - an estimated $6 million annually to drop bait laced with birth-control chemicals. Since the program first began in 2002, it has resulted in the removal of 5 million nutria. In fact, it’s an international event dedicated to de-stigmatizing toilets and address the challenges of global sanitation. Neither of these control methods is likely to be used in the near future.

Their populations in those locations are kept in check by the seasonal drought-flood cycles. [34] While nutria are the most common herbivores in Louisiana marshes, they are not the only ones. Female nutrias have nipples on their flanks so they can feed their young in the water. "The only effective means we have is trapping and/or shooting nutria," Gehring said. State agencies from Maryland, Virginia and Delaware have partnered with the U.S. Department of Agriculture and FWS to eradicate local nutria populations. [32][33] They eat the base of the above-ground stems of plants, and often dig through the organic soil for roots and rhizomes to eat. While once raised for their fur, nutrias have become a problematic invasive species. Some groups also use dogs to detect, track and trap nutria to prevent them from re-establishing their populations in locations where they had been removed, Gehring said. But other agencies and experts think a more offensive approach is better.
Four subspecies are generally recognized:[17], M. c. bonariensis, the subspecies present in the northernmost (subtropical) part of the coypu's range, is believed to be the type of coypu most commonly introduced to other continents.[16].
