| 0 | Ames 27866 | 19570423-B | Tsuga canadensis (L.) Carrière | Minnesota, United States | NC7 |  | Not Available | 2005 | COLLECTED | 1957 | Approximately 2.3 miles east of Lake Mille Lacs, near County Road 18 and Highway 27, T43N R25W NE 1/4 NE 1/4 Sec. 14, Mille Lacs County | 46.21150600, -93.45222700 | 391 | | Uncertain improvement status | Tsuga canadensis (eastern hemlock) is a long-lived conifer with a native range that extends from Nova Scotia west into Wisconsin and Minnesota and south along the Appalachian Mountains, Northern Georgia, and Alabama with outlier populations along the western range limits in Minnesota, Ohio, Indiana, Georgia, Alabama, Kentucky, and Tennessee (Ellingson, E. K. 2017). T. canadensis is one of Minnesota's rarest and most imperiled trees, listed as endangered in 2013 by the Minnesota Department of Natural Resources. To date (2021), less than 40 mature specimens exist today found at only two sites including: West Duluth (Carlton County) and Hemlock Ravine Scientific Natural Area (St. Louis County) (Ellingson, E. K. 2017). Genetics of this accession were acquired by sampling seeds in 2005 and 2006 from two specimens (open pollinated) growing at the Minnesota Landscape Arboretum in Chanhassen, MN (Specimens: 19570423-B and 19570423-G). The two trees sampled were originally acquired as seeds in 1957 from one of two native specimens near Mille Lacs Lake (Mille Lacs County), MN (population now extirpated). Based on work by Ellingson (2017), genetics of Mille Lacs Lake specimens were different from all other sites analyzed. This accession represents unique genetics (only maternal genetics known) from the extreme western edge of the species native range and thus important genetic resources for conservation. | 1699538 | Ames 27866 |
