Western larch (Larix occidentalis) makes up only 0.7% of British Columbia's total growing stock, yet it is a very important species, as it produces heavy, hard and strong wood. It is used mainly in building construction for rough dimension, small timbers, planks and boards, and for railroad crossties and mine timbers. As it is a visually appealing species, some high-grade material is manufactured into interior finish, flooring and doors.
Most western larch is produced as a Douglas-fir – Larch species mix, according to National Lumber Grades Authority (NLGA) structural grades for dimension lumber. Select Structural, #2 and better, and stud grades are the most common.
