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. Grain Straight Figure Growth rings (figure) Even Stripe (figure) Weak (figure) Straight Clear growth rings (figure) Weak figure Striped figure Texture Medium Fine Coarse Fine Uniform Even with narrow growth rings to coarse with wide growth rings 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 Planes well, to a good finish 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 Easy to Work Easy to machine Easy to work with hand tools except when interlocked grain is present Routing & Recessing Routing yields good results Routing is easy Turning Good results Easy to turn Painting Good results Polishing 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.
