Eastern Hemlock
The genus Tsuga contains about four
species native to
North America and ten to southern and eastern Asia. The 2 main
North American species are Eastern Hemlock &
Western Hemlock,
which can be separated microscopically. The wood of all species
in this genus looks alike microscopically. The species native
to North America are listed below.
Eastern hemlock is native to Cape Breton Islands,
Nova Scotia, Prince Edward Island, New Brunswick, the Gaspe’
Peninsula of southern Quebec and Maine, west to southern Ontario,
northern Michigan, Wisconsin, and eastern Minnesota, south to
Indiana and east to Ohio, Pennsylvania, Maryland and New Jersey
and south in the mountains to northwestern South Carolina, northern
Georgia and northern Alabama. The production of eastern hemlock
lumber is divided fairly evenly between the New England States,
the Middle Atlantic States, and the Lake States. Mature eastern
hemlock trees commonly attain heights of 100 ft (30.48 m), and
diameters of 3 ft (0.91 m).
The heartwood of eastern hemlock is pale brown
with a reddish hue. The sapwood is not distinctly separated from
the heartwood but may be lighter in color. The wood is coarse
and uneven in texture and moderately light in weight limberness,
and hardness. Eastern hemlock is moderately low in strength, and
shock resistance, splintering easily when worked with tools. The
heartwood of eastern hemlock is slightly resistant to nonresistant
to decay. Eastern hemlock is used principally for pulpwood and
lumber in building construction and in the manufacture of boxes,
pallets, and crates. Click
