Figure 9. — The white pine 

 forest type at its best {Bel- 

 knap County). This pine 



stand is a rarity. 



The white pine, white pine-hardwood, and hemlock 

 types supply most of the annual sa\vlog harvest. 



Many of these stands occupy land that was once 

 used for crops and pasture. As the old fields were 

 abandoned, pure, even-aged stands of white pine took 

 over — particularly where heavy sod or light grazing 

 kept out the hardwoods. The pine even invaded the 

 heavy soils that are usually thought of as hardwood 

 sites. However, as the pine matured, the stands were 

 cut severely. Even on the lighter soils, the cutoxcr 

 site conditions are seldom favorable for pine seed- 

 lings, and the hardwoods are gradually taking posses- 

 sion of the land. 



The spruce-fir group (fig. 10) embraces the other 

 important softwood types. It occupies 13 percent of 

 the commercial forest area : 



Spruce-fir 366, 300 



Spruce-fir-hardwood 207, 100 



Cedar-tamarack-spruce 33, 900 



Total 607, 300 



These forest types make up the important pulpwood 

 forests. They are found typically on dominant soft- 

 wood sites; i. e., site? where conditions for regeneration 

 are more favorable for softwoods than for hardwoods
