North American river otters once lived in most of the major waterways of North America, but were devastated in the late 1800's and early 1900's by trapping and habitat destruction.

Otter populations have rebounded in many areas and otters are no longer threatened with extinction, but the international fur trade and lightening of hunting regulations both pose serious risks to the continued survival of these animals.

Field biologists at Association of Zoos and Aquariums accredited institutions are working through the AZA Otter Species Survival Plan (SSP) and with other conservation partners to monitor North American river otter populations and potential threats to the species. Tulsa Zoo and Living Museum is working with the University of New Mexico to survey otter populations in areas where otters are threatened in order to aid in conservation planning. Seneca Park Zoo is helping to track otters that have been released in New York and monitor the progress of restored populations. The Columbus Zoo and Aquarium, Palm Beach Zoo, and Little Rock Zoo are also supporting conservation of otters in South America by teaching otter care and conservation techniques to South American zoos.
