BLM Studies Millions of Acres in Western US for Possible Wilderness Designation

Introduction A section of the Federal Land Policy and Management Act of 1976 specifies the procedure for areas the US Bureau of Land Management manages that have wilderness qualities. In part, FLPMA specifies that within 15 years of its approval, the Secretary of the Interior shall review roadless areas of 20 km2 (5,000 acres) or more and roadless islands of public lands identified during the inventory as having wilderness characteristics described in the Wilderness Act of 1964. Further, the Secretary shall report to the President his recommendation as to the suitability of each area or island for preservation as wilderness. However, before any recommendations for, wilderness designation, mineral surveys shall be conducted by the US Geological Survey and the US Bureau of Mines to determine if any mineral values are present. And finally, a Presidential recommendation for wilderness designation becomes effective only if so provided by an Act of Congress. BLM Inventory Procedures To fulfill these legal requirements, BLM is inventorying the land it manages for wilderness qualities. Since the law sets special provisions for Alaska, BLM included in its inventory only the public lands it manages in the conterminous US. In 1980, after public input, BLM picked 967 areas to be considered as Wilderness Study Areas. All of the selected WSAs are in 11 western states and the areas total about 97,128 km2 (24 million acres). From these 967 areas, through its multiple-use planning system, BLM is making initial recommendations of areas to be considered suitable for preservation as wilderness. Those WSAs that BLM initially considers suitable for wilderness preservation will have mineral surveys conducted by the USGS and the USBM, to determine mineral values. Based on these mineral surveys and other resources information including wilderness qualities, the Interior Secretary will report to the President his recommendations on the WSAs suitable for wilderness preservation. To make the initial recommendation of suitability, BLM managers will need information about geology, energy, and mineral (GEM) resources as well as information about other resources. BLM has begun a GEM assessment program to provide its managers with that information. This program is designed to provide information for a WSA suitability decision process that aims to supply minimum necessary GEM information. In essence, the program will provide preliminary assessment of the mineral potential for each WSA. Assessing the WSAs To accomplish this, a two-phase program was designed. In phase one, only existing data are collected and used. In phase two, new data are generated and added to existing data. Phase two begins only if BLM geologists, mining engineers, or managers consider the information provided in phase one as inadequate. This avoids unnecessary work and expenses and allows the program to proceed without undue delay. Figure 1 shows the two-phase process, including BLM's GEM in-
