How has the terminology used in Forest Engineering and harvesting evolved?
The terminology used in forest engineering and harvesting has evolved over many years, beginning with the early lumberjacks who cut trees for homes and industry. With increased mechanization since the early 1940's, the meanings of some terms have changed, and many new terms have been added.

What is an old forest?
