COSEWIC assessment and update status report on the Athabasca Thrift, ssp. interior in Canada

Summary of Status Report

Athabasca thrift (Armeria maritima subsp. interior) is one of ten endemic vascular plants known to occur in the Lake Athabasca sand dune region of northwestern Saskatchewan. It was assigned a status of threatened by COSEWIC in 1981 because of its rarity and specialized habitat that were then threatened by an all-weather road from Cluff Lake to the south shore of Lake Athabasca. It is one of the most uncommon endemics in the Athabasca sand dunes. Its habitat is localized and fragile. Although the Athabasca sand dunes enjoy Provincial Wilderness Park protection there is reason to believe that pressures from mining and tourism will require continued vigilance.
