Southern river otter studies have been performed on the southern river otter to better understand its declining population numbers to be able to prevent the species from becoming extinct. Several of the known populations are found within national forests. One survey in particular was performed to determine if any of this species live within these protected areas. The author surveyed three parks in Argentina: Lanin, Puelo, and Los Alerces National Parks. The surveyors spoke with people who live and work near these areas, and looked for prints and droppings of the southern river otter, while also looking for signs of the American mink.
