Report prepared for the Lousiana Department of Wildlife and Fisheries. Nutria herbivory "is perhaps the least studied or quantified aspect of wetland loss". Worldwide Distribution, Spread of, and Efforts to Eradicate the Nutria (Myocastor coypus) USGS National Wetlands Research Center http://www.nwrc.usgs.gov/special/nutria/index.htm, CONABIO. Increasing fertilizer inputs in marshes only increases nutria biomass instead of the intended vegetation, therefore increasing nutrient input is not recommended. 155pp. Suppl.  Originally native to subtropical and temperate South America, it has since been introduced to North America, Europe, Asia, and Africa, primarily by fur farmers. In Brazil, the animal is known as ratão-do-banhado (big swamp rat), nútria, or caxingui (the last from the Tupi language). The habitats of two national treasure species in Japan - a critically endangered dragon fly (see Libellula angelina in IUCN Red List of Threatened Species) and a fish the vulnerable deep-bodied bitterling (see Acheilognathus longipinnis in IUCN Red List of Threatened Species) (Shirow Tatsuzawa, pers. As a result, populations of coypus often contract and even become locally or regionally extinct as in the Scandinavian countries and such US states as Idaho, Montana, and Nebraska during the 1980s. Carter, Jacoby., 2007. It was introduced to the British Isles in 1929 when fur farms were set up in Sussex, Hampshire, Devon and Norfolk. Genovesi, P. 2005. This species has been nominated as one of the "100 of the World's Worst" invaders by IUCN. The handle is Black G10 and the steel is 5Cr15 stainless. , Coypus are found most commonly in freshwater marshes, but also inhabit brackish marshes and rarely salt marshes. There were three unsuccessful attempts to control coypu in east Great Britain between 1943 and 1944.  Being one of the world's larger extant rodents, a mature, healthy coypu averages 5.4 kg (11 lb 14 oz) in weight, but they can reach as much as 10 kg (22 lb).  Male coypus reach sexual maturity as early as four months, and females as early as three months; however, both can have a prolonged adolescence, up to the age of 9 months.  Each CEI official keeps record of how many tails have been turned in by each individual per parish, the method used in capture of the nutria, and the location of capture. Myocastor coypus (coypu) is a large semi-aquatic rodent which originated from South America. Coypu Species Alert., Kilkenny, Ireland: Heritage Council. We describe the reproductive biology of the coypu, Myocastor coypus (Molina, 1782), in western Japan, as an attempt to contribute to an efficient population control program of the coypu population. Nutria, (Myocastor coypus), a large amphibious South American rodent with webbed hind feet. The LDWF has estimated costs for new chemicals to be $300,000 for laboratory, chemistry, and field studies, and $500,000 for a mandatory Environmental Impact Statement. 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. December 2007. Habitat loss caused by coypus impacts plant, insect, bird and fish species. For instance, the U.S. A female coypu can become pregnant again the day after she gives birth to her young. Neither of these control methods is likely to be used in the near future.  In 1940, some of the nutria escaped during a hurricane and quickly populated coastal marshes, inland swamps, and other wetland areas. or SECTOR (e.g., Renewal Energy, Housing, etc. Carter, Jacoby and Billy P. Leonard: "A Review of the Literature on the Worldwide Distribution, Spread of, and Efforts to Eradicate the Coypu (Myocastor coypus)" Wildlife Society Bulletin, Vol. Journal of Wildlife Management 14:249–265. Tatsuzawa, Shirow. Foto over De mening van de close-up aan coypu in rivier. Gophers are common to North and Central America. Mammalian Species 398: 1-8. The coypu lives in burrows alongside stretches of water, and feeds on river plant stems. Habitat destruction caused by coypu threatens rare marshland species of bird, fish and invertebrates. It has a stout body that is highly arched and a large, somewhat triangular head.  According to the Louisiana Department of Wildlife and Fisheries, nutria were also transplanted from Port Arthur, Texas, to the Mississippi River in 1941 and then spread due to a hurricane later that year.  The survey revealed through aerial surveys of transects that herbivory damage to wetlands totaled roughly 90,000 acres. Free Online Library: Nutria (myocastor coypus) in big bend national park; a non-native species in desert wetlands. Global Invasive Species Database (GISD). Nutria Prevention and control of wildlife damage.  The LDWF has determined the wetlands affected by nutria decreased from an estimated 80,000+ acres of Louisiana wetlands in 2002–2003 season to about 6,296 acres during the 2010–2011 season. A coypu was first sighted in the wild in Ireland in 2010. The 24 trappers were offered an incentive for early completion of the 10-year campaign. http://www.feral.org.au/feral_documents/PC12803.pdf. The handle is Black G10 and the steel is 5Cr15 stainless. Coypu. “We have a lot of requests from a variety of LE and government employees for affordable folders, and the Coypu falls in line with their requests.” Designed as an ‘all-bases-covered’ folder for users on a budget, the Coypu brings a 3.75-inch drop point blade to bear, made from 8Cr15 steel. 1987. 1990). The National Biodiversity Data Centre issued a species alert in 2017, saying that coypu "[have] the potential to be a high impact invasive species in Ireland. 30(1): 162-175. Gosling, L. M. 1989. They generally line nursery nests with grasses and soft reeds. Journal of Applied Ecology 25: 49-62. Eds. The Louisiana Coastwide Nutria Control Program provides incentives for harvesting nutria. Coypu, also known as nutria, are native to South America, where they are eaten by alligators, large snakes and eagles.

Once a female is pregnant, gestation lasts 130 days, and she may give birth to as few as one or as many as 13 offspring. Wildlife Monograph 65: 43.  Also, an intensive environmental assessment would have to be completed to determine whether any non-target organisms were affected by the contraceptive chemicals. At high densities coypu are able to convert marshland to open water by feeding on plants. 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.

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. The next year, LDWF performed the same survey and found the area damaged by herbivory increased to about 105,000 acres.  They have coarse, darkish brown outer fur with soft dense grey under fur, also called the nutria. New Scientist, 4 march 1989: 44-49. Myocastor coypus (coypu) are generally found near permanent water, particularly reed beds and swamp/marsh. The coypu (from Spanish coipú, from Mapudungun koypu; Myocastor coypus), also known as the nutria, is a large, herbivorous, semiaquatic rodent.

In some places, they’re better known as coypu… , Besides breeding quickly, each coypu consumes large amounts of vegetation. Testing of other potential contraceptives would take about five to eight years and $10 million, with no guarantee of FDA approval. ", "Louisiana is losing a football field of wetlands an hour, new U.S. Geological Survey study says", "Jefferson Parish Sheriff Harry Lee dies", "Monitoring Plan: Project No. The response was to capture individuals, increase public awareness and provide a mechanism for reporting sightings (, Invasive Species Specialist Group (ISSG) (2011), Valli di Argenta a designated IBA (Important Bird Area), US Fish and Wildlife Service,
