This report describes the technical approach and results of a wildlife monitoring program conducted at the Seminoe No. I Mine for Arch Mineral Corporation (Arch) by western Resource Development Corporation (WRD) of Boulder, Colorado. The report is based on monthly field surveys by Arch personnel from September 1983 through March 1984, and by WRD personnel from April 1984 through August 1984. The purpose of the annual wildlife monitoring program is to fulfill a commitment contained in the Wyoming State Program Permit Application for the Seminoe No. I Mine (Arch 1979) and to satisfy applicable guidelines of the Wyoming Department of Environmental Quality (WDEQ) and Wyoming Game and Fish Department (WGFD). The compliance monitoring program is intended to document long-term patterns of wildlife occurrence, abundance, and habitat use in conjunction with mining and reclamation activities in the permit area. The program emphasized big game, game birds, and raptors, but other species observed during the surveys also were recorded. The annual monitoring period covered by this report was from September 1983 through August 1984. Additional information on the wildlife resources of the Seminoe No. I Mine study area is provided in the Wildlife Baseline Study (Arch 1979) and Annual Wildlife Monitoring Reports (Arch 1980, 1981, 1982, 1983). The baseline and previous monitoring reports are included in Appendix 0-9 of the Wyoming State Program document for the Seminoe No. I Mine. Additional copies of this report are provided to the Wyoming Game and Fish Department (WGFD), the U.S. Bureau of Land Management (BLM) and the U.S. Fish and Wildlife Service (USFWS).
