Tamaracks are interesting trees in that they are deciduous conifers, belonging to a genus of conifers that shed their needles: larix. These trees are conifers because they reproduce by means of cones, and have needles like most conifers; however, they shed their needles in the fall like deciduous trees shed their leaves. These needles are soft, grow in clusters, and are approximately one inch in length. Cones are small, only 1-2 cm in length.

Needles are food for ruffed and sharp-tailed grouse, snowshoe hare, red squirrel, porcupine, and deer; the cones and bark are also fed upon by these animals. 

The bark of a tamarack starts out smooth and grey, but can become more scaly and reddish as it ages. Branches are whorled, and are usually horizontal but can ascend slightly as well.

They typically grow to around 20 meters in height, and the average lifespan is 150-180 years.
