| 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

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 ).
