!The Tree
The Western Larch is a tall, straight tree towering from 150 to 200 feet high with a trunk diameter up to five feet. It is free of branches for 60 to 100 feet making it an increasingly valuable forest tree. The branches are short, horizontal and sparsely covered with foliage. The needles, growing in clusters along the small branches, are short, pointed, triangular, and ﬂat on their upper surface. They are a satiny pale green color. The Larch species (including Eastern Tamarack) shed their foliage each fall. Growing close along the branches are the egg-shaped cones, which are about one and a half inches long and one inch wide with slender bracts extending from each cone seed scale. The dull reddish cinnamon-brown bark of Western Larch has a striking appearance. It is three to six inches thick on mature trees, deeply furrowed and separates into rather small rather bright irregular scales. The tree withstands ﬁre damage better than most forest trees but is susceptible to attack by fungi of various kinds, and by the larch saw-fly.

!Growth Range

!The Wood
The heartwood of Western Larch is a reddish-tan or russet while the narrow sapwood is a yellowish-white to a pale straw-brown. The wood is moderately strong, stiff, medium heavy (it is the heaviest of all larch species and also the heaviest coniferous wood), ﬁne straight-grained and coarse-textured. It splits easily, but is not slivery as is the Eastern Tamarack. Because the base trunk of the tree is subject to “shake” or disintegration along the growth rings, the largest log of the tree maybe left in the woods. The wood closely resembles the ((Douglas Fir|Douglas Fir)) but is far inferior and is not used for veneers. It is somewhat difﬁcult to work with tools and does not hold paint well, but it is easily glued and easily stained and ﬁnished in natural color.

!Uses
This wood is used for dimension lumber of all kinds, some for interior ﬁnish, boat lumber, boxes, the cheaper grades of furniture, sash and doors, telephone and telegraph poles, railroad ties, posts, mine timbers. It is used to some extent for paper pulp in the manufacture of ﬁberboard and kraft wrapping paper. Some commercial use is made of the galactan gum extracted from the wood.
