Physical and Environmental Profile
==================================
Environmental Profile
Paper birch is rather widespread, abundant, and
secure globally,
though it may be quite rare in parts of its range, especially at
the periphery
(Source - The Nature Conservancy -Rank of relative endangerment
based primarily
on the number of occurrences of the species globally).
Distribution
Paper birch is reported to be distributed in
Alberta, British Columbia, Lebanon, Manitoba, New Brunswick,
Newfoundland, Nova Scotia, Ontario, Prince Edward Island,
Quebec,
Saskatchewan, and Yukon Territory in Canada.
In the United States, it is reported to occur in
Alaska, Colorado, Connecticut, Iowa, Idaho, Massachusetts,
Maine,
Michigan, Minnesota, Montana, North Dakota, New Hampshire, New
Jersey,
North Carolina, Illinois, New York, Ohio, Oregon,
Pennsylvania,
Rhode Island, South Dakota, Virginia, Vermont, Washington,
Wisconsin,
West Virginia, Nebraska, Tennessee, Indiana, Wyoming.
Paper birch is usually found in nearly pure stands,
and the tree prefers moist upland soils and cutover lands.
Product Sources
Some material from this species is reported to
be available
from environmentally responsible sources.
Tree Data
The mature tree is usually between 50 and 70
feet (15 and 21 m) high,
with a trunk diameter of 12 to 24 inches (30 and 60 cm).
Heartwood Color
The wood is described as creamy white in color,
often with a brownish central core.
Grain
The wood can be described as straight
grained.
A natural attractive figure is reported to make birch a very
desirable timber for furniture.
Texture
Texture is described as even.
Natural Durability
The timber is reported to have very little
natural resistance to decay,
and should not be used under high decay hazard conditions.
Resistance to Impregnation
The heartwood is reported to be fairly difficult
to treat with liquids.
Planing
Planing properties are reported to be only fair,
and the wood tend to chip and tear.
A reduced cutting angle of 20 to 25 percent has been recommended
for best results.
(Percent of planed pieces without any machining defects =
47).
Turning
Turning qualities are rated as excellent.
Moulding
The wood is reported to respond poorly to
moulding operations, and surfaces tend to be rough.
(Percent of moulded pieces yeilding good to excellent results
out of 100 samples = 22).
Boring
The wood is reported to bore very well,
and bored holes are generally smooth and uniform in size.
Mortising
Mortising qualities are rated as very
good.
Gluing
Under properly controlled conditions,
Paper birch is reported to bond to produce joints of good
strength.
Darker colored glues are reported to produce conspicuous
glue lines because the wood is lighter colored and also
porous.
Nailing
Resistance to splitting in nailing operations is
reported to be
good but pre-drilling is recommended during hand nailing.
Nail-holding properties are rated as very good.
Screwing
Pre-drilling is suggested during screwing to
prevent splitting,
but the material is reported to hold screws very well.
Sanding
Smooth surfaces are reported to be difficult to
achieve in sanding.
Polishing
The timber is reported to polish well without
grain filling.
Staining
Dyes and clear stains are reported to be
preferable to heavily pigmented finishes,
since the latter tends to give the wood a muddy appearance.
Surface scratching is reported to be a common problem.
Strength Properties
Bending strength in the air-dry condition (about
12 percent moisture content) is high.
It has medium crushing strength. It is moderately hard and
resistant to wearing and marring.
It is a heavy wood.
