In this technical memorandum, WestLand Resources, Inc. (WestLand) describes the likely range of effects of the proposed action and action alternatives being considered by the Tonto Nation Forest in their environmental analysis of the proposed Rosemont mine project to riparian habitat along Davidson Canyon. The Study Area encompassed lower Barrel Canyon from just west of Highway 83 to the confluence with Davidson Canyon and continued downstream in Davidson Canyon to the confluence with Cienega Creek (Figure 1). WestLand has previously analyzed the riparian habitats and described the vegetation characteristics and species composition that occur along the Study Area (WestLand 2011; Figure 2).
