The grey birch, common throughout P.E.I., is a small tree, rarely over 10m in height and a diameter of 20cm. The trunk is slender and usually extends undivided to the top of the open, pyramidal crown. The slender branches divide into many fine flexible branchlets that are inclined to droop. A characteristic mark of this birch is the triangular black spot beneath each branch. It is one of the first trees to spring up after a fire, and is found on dry gravelly or sandy soils, however, it sometimes is found on wet soils along the margins of streams and swamps.

Grey birch exists in pure stands but is more commonly mixed with spruce, balsam fir, larch, white birch, and poplar.

Its wood is of little commercial importance being used locally for fuelwood and barrel hoops.
