The Saimaa ringed seal has been protected since 1955. In 1983, the population was between 100 and 150 seals. In 2005, it was about 270, but as a result of two unfavorable breeding seasons, 2006 and 2007, the number dropped down to 260. In 2013 the population was estimated at just over 300 and the population numbers were in a slight growth. The number of breeding-aged females was 87. It is thought that the immediate threat of extinction would be alleviated if the population grew to over 400 individuals. It is listed as endangered by the U.S. government under the Endangered Species Act.
