Environmental
Profile
The conservation status of this species within its
natural growth range is unknown because of lack of
information (Source - World Conservation Monitoring
Center - 1992).
Distribution
The natural growth range of the species is reported to
be Paraguay, Uruguay, and Argentina, and occurs in high
concentrations in central and southeastern Brazil.
Product Sources
It is currently unknown whether lumber and other wood
products from this species are available from
environmentally reponsible sources.
Tree Data
The tree is reported to mature to a medium height, with
a rather large trunk that reaches a diameter of about 48
inches (120 cm).
Sapwood Color
The sapwood is pinkish in color and is not always
distinct from the heartwood.
Heartwood Color
The heartwood is described as often dull red or maroon,
but may be lighter colored. Purplish markings are
reported to be a common feature.
Grain
Grain is reported to be generally straight, but is
sometimes wavy.
Texture
Texture is medium to coarse.
Luster
Luster is reported to be medium to low.
Odor
Freshly-cut wood is reported to have an aromatic smell.
Seasoned wood has no distinct odor or taste.
T/R Ratio
2.33
This indicator is more meaningful if it is used together
with actual shrinkage data in the tangential and radial
directions. (Refer to the Numerical Values window).
Natural Durability
The heartwood is reported to have a high natural
resistance to attack by decay-causing fungi and other
wood destroying insects.
Veneering Qualities
The timber is reported to be peeled and sliced into
veneer.
Planing
Cangerana is reported to respond readily to ordinary
tools in planing and other machining operations and
works to yield clean, smooth finishes.
Strength Properties
Bending strength in the air-dry condition (about 12
percent moisture content) is high - comparable to Teak.
Maximum crushing strength, or compression strength
parallel to grain, is high. Some familiar species with
high crushing strength parallel to grain include Hard
maple, Teak, and White oak. The wood is high in density.
