Rosemont Copper Company (Rosemont) proposes to develop an open-pit copper mine with associated processing facilities and waste disposal sites within the Rosemont Holdings, which encompass patented and unpatented claims and fee lands within privately owned, USDA Forest Service (Forest), and Bureau of Land Management (BLM) lands on the northeast side of the Santa Rita Mountains (Figure 1). Rosemont has authorized WestLand Resources, Inc. (WestLand) to conduct a variety of baseline biological studies within the Rosemont Holdings. As part of the baseline biological studies, WestLand has conducted surveys of the Rosemont Holdings and their vicinity for ranids, particularly the Chiricahua leopard frog (Rana [Lithobates] chiricahuensis), which is listed by the US Fish and Wildlife Service (USFWS) as threatened under the Endangered Species Act (ESA), and the lowland leopard frog (Rana [Lithobates] yavapaiensis), which is considered a sensitive species by the Forest and the BLM.
