Scientific Harvesting of FineTimber Stands

fo the men of Weyerhaeuser, it is necessary to see BOTH the forest and the trees as part of the job of producing good quality lumber on a continuing basis.

Progressive forest management, as practiced by Weyerhaeuser, is based on a policy of permanent mill operations within prescribed timber areas. In this prograrn, the timber harvest for each year is prudently scheduled.

There are two methods of harvesting mature timber block logging and selective loggrng. Block logging is clear loggrng of mature trees. Islands of seed trees are left to re-seed the cutover blocks. This returns the land to productive utility with trees of uniform age.

In selective logging, certain trees are removed, Ieaving room for the development of young timber. The type of loggrng pursued depends upon the type and location of the forests involved. As a further means of re-stocking the forest lands, manual and mechanical planting of seedlings are employed where natural re-seeding does not take place.

Weyerhaeuser forest and mill practices have been constantly improved and modernized, always with the view of increasing the forest yield, and obtaining more usable products out of every tree.

A continuous supply of better quality lumber for present and future needs is the program behind every piece of lumber bearing the brand name "Weyerhaeuser 4-Square".
