They breed year-round, producing up to 3 litters per year, with 2-13 young per litter. [61], Nutria herbivory "severely reduces overall wetland biomass and can lead to the conversion of wetland to open water. [43] While nutria are the most common herbivores in Louisiana marshes, they are not the only ones. The average capybara is 40-50 inches long, while the average nutria is 15-25 inches long. Some states are even paying hunters to cull them. A culinary event called Nutriafest was launched to promote eating the invasive rodent.

Once introduced, nutria populations increase quickly and can produce their first litter in 8 months.

Fortnite Montage Intro, Although nutria populations were greatly reduced after the 19621965 campaign ended, the population increased until another eradication campaign began in 1981. [62] These very biodiverse systems provide resources, shelter, nesting sites, and resting sites (particularly Louisiana's coastal wetlands such as Grand Isle for migratory birds) to a wide array of wildlife. In response, by 2003, a multimillion-dollar eradication program was underway. [49] In 1940, some of the nutria escaped during a hurricane and quickly populated coastal marshes, inland swamps, and other wetland areas. Capybaras are members of the Caviidae family, while nutrias are members of the Myocastoridae family. Currently nutria immigration is monitored for habitat destruction of wetlands, farmlands, marshes and is measured in habitat loss in acres. Nutria are still present in Japan and there is currently a restriction on importing, transporting and obtaining nutria per the Invasive Alien Species Act established in 2004.[87]. Increasing fertilizer inputs in marshes only increases nutria biomass instead of the intended vegetation, therefore increasing nutrient input is not recommended. Like all flying squirrels, the red giant is arboreal and nocturnal. Capybaras live in grassy or marshy regions with water close by at all times, while nutrias create complicated burrows along riverbanks or ponds. The Laotian giant is the second known species of the Biswamoyopterus genus. In the U.S., nutria have been found in 30 states, but are currently established in as many as 18, including Washington, and Oregon. Capybaras enjoy living in large herds, especially in grassy areas.

[51]:1920 In the Chesapeake Bay region in Maryland, where they were introduced in the 1940s, nutrias are believed to have destroyed 2,800 to 3,200 hectares (7,000 to 8,000 acres) of marshland in the Blackwater National Wildlife Refuge. They were first brought to Louisiana in the early 1930s for the fur industry, and the population was kept in check, or at a small population size, because of trapping pressure from the fur traders. [26] A female on average will have two litters a year. An adult nutria is about 1/3 the size of an adult beaver and over 5 times the size of a muskrat.

However, beavers' tails are flat and paddle-like, as opposed to the round tails of coypus.[29]. [5] Nutria herbivory "is perhaps the least studied or quantified aspect of wetland loss". Eating, digging, and rooting habits cause erosion and convert healthy marsh into open water habitat. 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.
