Distribution and adaptation
The soils on which balsam fir grows range from silt loams developed from lake deposits to stony loams derived from glacial till. Fir will grow, but comparatively slowly, on gravelly sands and in peat bogs. It grows on soils of pH ranging from 4.0 to 6.0. It is generally found in areas with a cold moist climate and with 30 inches or more of annual precipitation. Fir is subject to windthrow, especially on shallow wet soils. Because of its thin bark, shallow root system, and flammable needles, balsam fir is easily killed by fire.
Balsam fir is distributed throughout the Northeast and upper Midwest. For a current distribution map, please consult the Plant Profile page for this species on the PLANTS Website.
