A TYPICAL EVEN-AGED WESTERN WHITE PINE FOREST 
This stand in northern Idaho is about 160 years old and ready to yield 50 or 60 thousand board 
feet to the acre. With clear cutting, careful slash disposal, and subsequent prevention of fire, 
this forest will be succeeded in 70 to 90 years by a **second-growth”’ forest of merchantable 
size
