seeding of cutover areas. The large percentage of 

 yellow birch is most likely dependent on the moisture 

 content of the soil. The area bordered the upper 

 limits of the spruce flat type, where the amount of 

 moisture was quite large, one of the requirements for 

 the best development of yellow birch. In the case of 

 beech, its restricted seeding, its non-aggressiveness 

 in reseeding cutover areas and the need for shade 

 for best development, accounts for the small percentage 

 of the stand it occupies.
