Coypus are not currently threatened, according to the World Conservation Union (IUCN). Their numbers are declining along many rivers and lakes in Argentina due to hunting and trapping by humans. The eradication efforts in the United States, France, and Japan are likely to significantly reduce populations in those areas.
