Upland hardwoods, occurring rather generally on 

 well-drained sites, form the prevailing forest cover in 

 all survey regions. They occupy some 8.4 million 

 acres and comprise 68 percent of the total commercial 

 forest area (fig. 13). Various oaks — chiefly black, 

 scarlet, southern red, and white — hickory, and yellqw- 



poplar together make up three-fourths of the net 

 cubic volume of the type. Other common associates 

 include sweetgum, blackgum, maple, elm, ash, and 

 beech. Small quantities of pine are also interspersed 

 on one-quarter of the type acreage classified as upland 

 hardwood-pine.
