Range. River otters can be found in streams, lakes, reservoirs, wetlands and along marine coasts in all states and territories of the United States and Canada. River otters are being reintroduced in the Rocky Mountain region to counter the population decrease in the 1800s.
River otters choose their habitat based on how much food and shelter they can find. As a result, their habitat can change depending on the season. For example, they will move from temporarily flooded marshes to cypress swamps that have permanent ponds.ince the otters keep their young on land, they need either vegetation or rock structures as shelters or dens. The Lontra Canadensis requires a large amount of space, often up to 50 miles. Development of cities, pollution, pesticides, and other man-made poisons destroys their habitat and decreases their numbers.
