PRESENT FOREST TYPES 



The forests of tliis region are made up of 50 or 

 more common tree species mixed in various combi- 

 nations. For simplicity they are described under 

 four forest type groups (table 3). 



Northern pine group: The northern pine types 

 consist of white pine, red pine, and jack pine, three 

 commonly recognized forest types (table 4). 



The once prominent white pine type {30) now 

 occupies only 2 percent of the forest land. Only 

 scattered remnants of the virgin forest reinain (fig. 

 6). Natural reproduction is not extensive and very 

 little nursery stock is being planted because of 

 prevalence of white pine weevil, blister rust, and 

 other natural enemies. On the other hand, scat- 

 tered white pine trees occur rather commonly in 

 other types and with care may gradually extend the 

 range of the type (fig. 7).
