Tamarack (Larix laricina), also called eastern, American, or Alaska larch, and hackmatack, is a small- to medium-sized deciduous conifer extending from the Atlantic to central Alaska. One of the largest tamaracks recorded is in Maine and measures about 94 cm (36.9 in) in d.b.h. and 29 m (95 ft) in height. The heavy, durable wood is used principally for pulpwood, but also for posts, poles, rough lumber, and fuelwood. Wildlife use the tree for food and nesting; it is also esthetically appealing and has significant potential as an ornamental.
