Abies balsamea var. phanerolepis
|Scientific Name:||Abies balsamea var. phanerolepis|
See Abies balsamea
|Taxonomic Source(s):||Farjon, A. 2010. A Handbook of the World's Conifers. Koninklijke Brill, Leiden.|
|Red List Category & Criteria:||Data Deficient ver 3.1|
|Reviewer(s):||Thomas, P. & Stritch, L.|
Abies balsamea var. phanerolepis is assessed as Data Deficient. The subpopulations of this variety are undoubtedly relatively small and scattered (fragmented) but there is insufficient information about their number, extent of occurrence (EOO) and area of occupancy (AOO) for a credible assessment to be made. Another problem is identity and several reports and specimen databases of herbaria list occurrences of this variety in Canada (e.g. Nova Scotia at the Harvard Herbaria) which are likely to be just forms of A. balsamea var. balsamea with (slightly) exserted bracts.

|Population:||There is very little information available on population size or trends that is specific to this variety.|
|Current Population Trend:||Unknown|
|Habitat and Ecology:||Occurs in the highest parts of the Appalachian Mountains, forming more or less pure stands or mixed with Tsuga canadensis and/or broadleaved trees e.g. Acer spp.|
|Continuing decline in area, extent and/or quality of habitat:||No|
|Generation Length (years):||50|
|Use and Trade:||In recent years, this variety has gained popularity as a Christmas tree in the USA and it is therefore grown in tree nurseries for that purpose. The timber is also used for construction purposes.|
|Major Threat(s):||The subpopulations in the mountains of Virginia and West Virginia form the southernmost extent of the species and are scattered and isolated. Fires, pathogens and air pollution from industrial centres are (potential) threats.|
|Conservation Actions:||This variety occurs in many protected areas.|
