|Taxonomic Source(s):||Farjon, A. 2010. A Handbook of the World's Conifers. Koninklijke Brill, Leiden.|
|Red List Category & Criteria:||Least Concern ver 3.1|
|Reviewer(s):||Thomas, P. & Stritch, L.|
This is the most widespread species of Abies in North America. It is a component of the great Boreal forest of Canada, a dynamic ecosystem that is destroyed locally by natural causes but regenerates continuously. The typical variety, is assessed as Least Concern.
|Range Description:||Recorded from Canada, North Central and E USA: south to Virginia. The extent of occurrence and area of occupancy are well beyond 20,000 km2 and 2,000 km2 respectively. Several reports and specimen databases of herbaria list occurrences of variety phanerolepis in Canada (e.g. Nova Scotia at the Harvard Herbaria) but these are likely to be just forms of A. balsamea var. balsamea with (slightly) exserted bracts.|
Native:Canada (Alberta, Labrador, Manitoba, New Brunswick, Newfoundland I, Nova Scotia, Ontario, Prince Edward I., Québec, Saskatchewan); United States (Connecticut, Iowa, Maine, Massachusetts, Michigan, Minnesota, New Hampshire, New Jersey, New York, Pennsylvania, Vermont, Virginia, West Virginia, Wisconsin)

|Current Population Trend:||Stable|
|Habitat and Ecology:||Abies balsamea occurs from lowland plains to upland hills and mountains in the vast Boreal forest of North America, from sea level to 1,200 m a.s.l. in West Virginia, with an isolated station on Mt. Washington (NH) at ca. 1,900 m. It is most common on usually podzolized moderately acid soils in silt or sand. In some areas it may also grow on wet, peaty soil. The climate is cold continental in the interior, cool maritime in the eastern part of the range, with precipitation between 250 and 1,250 mm and very cold winters. The growing season ranges from 80 days in the interior of Canada to 180 days in the Appalachian Mountains. It is a constituent of coniferous forests with Picea spp., Pinus strobus, Tsuga canadensis and sometimes Pinus banksiana, or it grows mixed with broad-leaved trees such as Populus tremuloides, Betula spp. and, further south, Acer spp., Fagus grandifolia and Betula alleghaniensis. Taxus canadensis is the most common conifer shrub in these mixed forests.|

|Use and Trade:||Balsam Fir is an economically important conifer. Its wood, although of modest size, is used in light-frame construction and for pulpwood. It is also popular as a Christmas tree and is one of the top three species grown for this purpose in E North America. The fragrant needles are partly responsible for this popularity, they are also used to stuff pillows sold as souvenirs in New England. Canada balsam, the aromatic and soft terpenoid resin collected from blisters in the bark, is especially important in Quebec. Its medicinal properties were known to Native Americans, who used it as an antiseptic wound dressing as well as internally for various ills. Lewis and Clark had it in their medicine box on their famous overland expedition to the Pacific Ocean in 1804-05. In modern Western society its medicinal use has been replaced by other salves; the resin is now used to seal microscopic glass slides with biological preparates. In horticulture, Balsam Fir is less valued; this fir is apparently short lived when planted in gardens and only a few dwarf cultivars are known|
|Major Threat(s):||No specific threats have been identified for this variety.|
|Conservation Actions:||This species occurs in many protected areas.|
