Environmental Profile
Decreasing in numbers
Data source is World Conservation Monitoring Center
Could become endangered if current trend persists
Considered vulnerable in its natural habitat because its numbers are threatened by serious adverse factors throughout its range. However, the species likely exists today in relatively large numbers.

These trends include over exploitation, extensive destruction of habitat, uncertainty of future security of remaining members

Distribution Overview
The species occurs in the central region of Chile and in the Province of Chubut in southern Argentina. It grows primarily on marshy sites, and may also be found at higher elevations on Isla de Chiloe and in Patagonia. It form dense and nearly pure stands

Heartwood Color
Brown
Black
Green/grey
Reddish brown
Red
Brown, red, dark reddish brown with nearly black stripes after prolonged exposure
Yellow to golden-yellow to orange

The heartwood is described as a distinct brownish red in color, and is similar in appearance to California redwood (Sequoia).

Sapwood Color
Green/Grey
Brown
White-Yellow
Well defined
Paler than heartwood

The sapwood is a lighter color than the heartwood and is often clearly differentiated from the heartwood.

Luster
Low


Natural Durability
Durable
Resistant to termites
Durable
Very durable
Resistant to attack from powder post (Lyctid & Bostrychid) beetles

Alerce is reported to resist attack by white-rot and brown-rot fungi. Its high durability is considered unusual since it is a softwood.

Odor
No specific smell or taste


Light-Induced Color Change
Darker


Drying Defects
Splitting
Slight end splitting


Ease of Drying
Easy
Very little or no degade


Tree Identification
Bole/stem form is straight
Bole/stem form is cylindrical


Tree Size
Tree height is 0-10 m
Tree height is 10-20 m
Bark width is 10-15 mm
Bark width is 5-10 mm


Boles are often straight, well-formed Trunk diameters of 15 feet (4.6 m) are reported to have been recorded. Trunk diameters of 4 feet (1.2 m) under favorable growing conditions.

Product Sources
Alerce timber of large sizes and of good quality are still available from existing supplies of large, old trees.

The International Tropical Timbers Organization reports that only small quantities of Alerce are marketed because of the low number of trees remaining in the forest

Substitutes
Lerce has been suggested as a potential substitute for Redwood (Sequoia ).

Comments
General finishing qualities are rated as good

Blunting Effect
Blunting effect on machining is slight


Boring
Easy


Cutting Resistance
Fairly Difficult to Very Difficult to saw
Low resistance to cutting


Gluing
Easy to glue
Good gluing properties


Mortising
Finishes well
Easy to mortise


Moulding
Good finishing results
Easy to mould


Movement in Service
Stable
Small


Planing

Responds well to ordinary tools in planing and almost all machining operations
End-grain material requires very sharp cutting edges to produce a smooth finish
Easy to plane


Resistance to Impregnation
Heartwood is permeable


Response to Hand Tools

Very Good to Excellent Results
Fair to Good Results
Satisfactory results
Good results


Staining
Finish is generally satisfactory
Takes stains well
Finish is generally good


Varnishing
Good results


Strength Properties
Density (dry weight) = 23-30 lbs/cu. ft.
Bending strength (MOR) = low
Modulus of Elasticity (stiffness) = very low
Max. crushing strength = low
Shrinkage, Radial = small
Shrinkage, Tangential = small
Hardness (side grain) = very soft
Shearing strength (parallel to grain) = very low
Max. crushing strength = medium
Density (dry weight) = 15-22 lbs/cu. ft.
Work to Maximum Load = very low
Shrinkage, Tangential = very small
Shrinkage, Radial = very small
Surfaces may dent easily
Soft
Shrinkage, Tangential = moderate
Shrinkage, Tangential = fairly large
Shrinkage, Radial = moderate
Shearing strength (parallel to grain) = low
Moderate density
Max. crushing strength (stiffness) = very low
Does not wear well and mars easily
Density (dry weight) = 38-45 lbs/cu. ft.
Density (dry weight) = 31-37 lbs/cu. ft.
Compression strength (parallel to grain) = low
Bending strength (MOR) = very low
Bending strength (MOR) = medium

Bending strength in the air-dried condition (about 12% moisture content) is medium, but lower than Mahogany, and much lower than White oak. It is weaker than Mahogany or Teak
