Basis for Former Listing
Symphoricarpos orbiculatus is native to prairie and prairie-like habitats in the central and eastern United States, which may or may not include Minnesota. Although several regional plant manuals report this species from Minnesota (Fernald 1950; Great Plains Flora Association 1986), none provide supporting documentation. Other sources are more equivocal; for example, Ownbey and Morley (1991) say "possibly present in the state only by introduction from farther east or south". Smith (2008) is even more doubtful, stating "... there is no strong evidence that it is either native or naturalized in Minnesota". As of 2010, there are no known voucher specimens of S. orbiculatus in any Minnesota herbarium that were definitively collected from a native Minnesota population (the 1979 Houston County specimen is believed to be from an introduced population). Symphoricarpos orbiculatus was listed as a special concern species in Minnesota in 1984.
Basis for Delisting
Because there is no evidence that this species is native to or naturalized in Minnesota, special concern status is not appropriate. Symphoricarpos orbiculatus was delisted in 2013.
