WestLand Resources, Inc. (WestLand) was retained by Rosemont Copper Company to conduct surveys for Hexalectris colemanii, Coleman’s coralroot; and H. arizonica, Arizona crested coralroot (Orchidaceae) in the Rosemont Area and at other occupied locations in southern Arizona as part of a series of baseline resource studies to support mine permitting efforts. In Arizona, H. colemanii and H. arizonica are found in mountain ranges of Cochise, Pima, and Santa Cruz counties (AGFD 2005 and 2004). Coleman’s coralroot is known to be present in the northern portion of the Santa Rita Mountains within the footprint of the proposed Rosemont Copper Mine (Figure 1). This species is a Forest Sensitive species in the Coronado National Forest (US Forest Service 2007).
