FOREST PLANTING LEAFLET. 



GREEN ASH (Fraxinus lanceolata). 



FORM AND SIZE. 



The green ash, when forest grown, is a medium-sized, round-topped 

 tree with a straight, undivided bole and slender, spreading- branches. 

 It rarely exceeds a height of 60 feet and a diameter of 24 inches. 

 Deep-seated, fibrous roots, which extend laterally, form the charac- 

 teristic root system. 



RANGE. 



Green ash is distributed over the greater part of the United States 

 east of the Rocky Mountains, even extending into those mountains in 

 Utah and New Mexico ; it occurs to the north as far as the Saskatche- 

 wan River in Canada. It is most abundant in the Mississippi basin, 

 and is rather infrequent in the East. In the timber belts along the 

 streams that drain the plains and prairie country of the Middle West 

 the green ash sometimes occurs as the leading species, but in general, 

 especially in the East, it appears singly or in small groups among 

 other hardwoods. The species most commonly found in such natural 

 mixtures are the white elm, hackberry, sycamore, black cherry, red 

 ash, and bur oak. 



At the present time the range for economic planting of green ash 

 hardly exceeds that of its natural distribution. It is probable that 

 this tree will prove valuable for planting on irrigated lands, in regions 

 now being developed throughout the arid West. 



HAB-iTS AND GROWTH. 



The green ash attains its best development on low, moist ground; 

 yet it can be grown more successfully on the upland than most other
