The Trumpeter Swan is currently designated as a
threatened animal under the Alberta Wildlife Act. In 1991, the Trumpeter Swan was assigned to Alberta's
Red List of species at risk in the province because of low population size and critical shortage of wintering
habitat. Because of the increase in the breeding population, the species was reassigned to the
Blue List in 1996. The Alberta Natural Heritage Information Centre lists the Trumpeter Swan as S3B in the province.
