The research reported here is part of the Guides to Land Management Project which was initiated by the Bureau of Land Management in 1965. The purpose of the Project is to provide resource managers with techniques for identifying alternative measures and their consequences. The work is addressed to the problems of decision making in a complex natural-resource system. This report presents a technique that helps managers understand the scope of their work. The method deals simultaneously with all the major resource activities on a BLM district, and it also suggests guides for evaluating alternative programs . Many of the illustrations involve ideas not commonly encountered in the everyday experience of forest managers, so the results need to be interpreted carefully. The report explains the method and illustrates its application on the BLM's Eugene District in Western Oregon. It is written to the practicing manager.
