Planning for timber-tract development
1967
Marty, Robert Jay | Trimble, George R.
S2Once a forest owner has decided to develop his property for timber production, his first concern is for the direction of development. This involves questions of species composition, method of management (even-aged or uneven-aged), and type of products to manage for. After these decisions are made, two basic problems arise. The first problem is to determine the optimum level of development for the ownership. This involves the questions of how much growing stock to carry; how far to go in trying to establish, protect, and improve growing stock; and how much investment in roads and other physical improvement is justified. The second problem is to decide how fast to move toward this optimum level of development.S3.
