FOREST PLANTING LEAFLET. 



TAMARACK (Larix laricina). 



FORM AND SIZE. 



The tamarack is a straight, slender tree, averaging about 60 feet 

 in height and 15 to 20 inches in diameter. It rarely attains a height 

 greater than 80 feet or a diameter of more than 30 inches. \Vhen 

 grown in the forest the tamarack has a clean, straight bole and a 

 narrow, pyramidal head. In the open this regular form is lost and 

 the crown becomes broken and spreading. 



RANGE. 



The tamarack has the widest range of all the conifers of the North- 

 east. It has its approximate southern limit in northern Pennsylvania, 

 Indiana, and Illinois, and extends northward to the Arctic Circle and 

 westward in the United States to central Minnesota. 



The tamarack is most plentiful in the swamps and silted lake 

 beds of northern regions, where it occurs in dense pure stands or 

 mixed with arborvitae and black spruce over vast areas. The best 

 specimens grow where the moisture is not excessive, on the edge of 

 swamps and along the banks of sluggish streams, in mixture with 

 balsam fir, black spruce, black ash, and arborvitae. Other natural 

 associates are the birches, red maple, sugar maple, tupelo, and occa- 

 sionally white pine. Although more common on lowlands, in places 

 it grows on mountain sides up to an elevation of 4,000 feet. It may 

 be planted in suitable situations throughout the Northern States 

 from the Atlantic to the Mississippi.
