WestLand Resources, Inc. (WestLand) conducted surveys in 2011 for four Coronado National Forest sensitive plant species in the Rosemont Project Area and in additional locations outside the Rosemont Area. These surveys are part of ongoing baseline biological studies in support of the National Environmental Policy Act process to obtain licensing for a copper mine in the northern Santa Rita Mountains. The four species considered here are Santa Rita yellowshow (Amoreuxia gonzalezii), beardless chinch weed (Pectis imberbis), Arizona manihot (Manihot davisiae), and southwestern muhly (Muhlenbergia dubiodes). Surveys were initiated in 2010 and continued in 2011 to determine if these species occurred in the project area and their abundance if present.
