The purposes of this Paper are to summarize and evaluate the available physical, biological, manage ment, and economic data for the Arizona pinebunchgrass ranges. It provides information intended to help public and private managers of forest-range lands in making resource management decisions, and to help researchers make decisions concerning possible new research directions. The information provided follows this sequence: physical-biological characteristics of the Arizona ponderosa pine type, factors influencing livestock (primarily beef) production, allotment conditions, economics, and correlation of grazing with other uses and demands. The following conclusions can be drawn from this information: 1. Considerable descriptive information is available for the Arizona ponderosa pine type. Knowledge of geographic, climatic, edaphic, and vegetation characteristics is adequate for use in reaching many management decisions. 2. The successional stages of the bunchgrass ranges appear to be sufficiently understood so that general range condition can be easily recognized. 3. A good background of range seeding information is available, and the causes of livestock losses from poisonous plants are understood. Ariz. U.S. Department of Agriculture. Forest Service. 1969.
