There is, of course, some more productive land on the North Slope. Nineteen percent 

 is classified as medium site. Medium site lodgepole pine land such as is shown in figure 

 5 can produce about 19 thousand board feet per acre of sawtimber in a rotation period. 



Figure 4. — The ponderosa pine forest 

 in the Manila District includes a 

 few small patches of excellent trees. 

 However, this is more than offset 

 by many acres of scrubby timber 

 such as this. The growth rate is 

 slow and the stand reestablishment 

 rate is even slower on these rocky 

 areas. 



Figure 5. — The best timber-growing 

 opportunity on the North Slope lies 

 in the 75,000 acres of medium site 

 land such as is pictured here.
