In November 2013, Resolution Copper Mining, LLC (RCM) submitted the proposed General Plan of Operations (GPO) to the Tonto National Forest, to develop and mine a copper-molybdenum deposit. Tonto National Forest deemed the GPO to be complete in December 2014 - see Letter of Completion. A plan of operations is a Forest Service permit, which authorizes mining operations on national forest lands.

The Research Ranch, near Elgin in Santa Cruz County, Arizona, is administered by the National Audubon Society. It consists of about 8000 acres of federal and private lands that are managed for ecosystem research projects by the National Audubon Society, which has cooperative agreements with the federal land management agencies. This summary of the early history of land settlement of the Research Ranch area and some of the subsequent land transactions is taken primarily from information in the land records of the BLM and ASLD.

The 7B Ranch falls within Audubon's identified "Lower San Pedro River Important Bird Area". The San Pedro River riparian corridor from the "Narrows" to the Gila River confluence was identified as a state Important Bird Area by the Arizona IBA Science Committee in January 2007. The Audubon IBA bird survey data collection coordinated by the Tucson Audubon-IBA Program, Avian Science Initiative, at 7B Ranch provided key "mesquite bosque avian habitat" data for these reviews.

WestLand was retained to conduct a range of ecological studies of several parcels of land. This report summarizes the biological resources of one parcel of U.S. Forest Service land (the Federal Parcel) and five privately owned parcels (the Offered Lands). The work was conducted in anticipation of a possible land exchange.

This report compares the floodplain and wetlands inventories for five offered lands ("Non-Federal Parcels") to the "Federal Parcel". The Non-Federal Parcels are: JX Ranch, Appleton Ranch, LX Bar Ranch, 6L Ranch, 7B Ranch. The Federal Parcel is also known as the Resolution Parcel, and will be so referenced in this report.

WestLand was retained to prepare an Ecological Overview for an approximately 357-hectare site in Santa Cruz County, Arizona.  This evaluation of the property was conducted to: Identify the types and relative condition of the biological resources found; Evaluate the ecological characteristics; Identify remarkable resource attributes and; Briefly assess the resource conservation values and opportunities in reference to local and regional contexts.

WestLand was retained to prepare and Ecological Overview for approximately 59.5 hectares of land along Turkey and Rock Creeks within the Tonto National Forest in Gila County, Arizona (referred to as JX Ranch). This evaluation of the property was conducted to: Identify the types and relative condition of the biological resources found; Evaluate the ecological characteristics; Identify remarkable resource attributes, and; Briefly assess the resource conservation values and opportunities in reference to local and regional contexts.

WestLand was retained to prepare an Ecological Overview for approximately 59.9 hectares of land along Tangle Creek within the Tonto National Forest in Yavapai County, Arizona (referred to as LX Bar Ranch). This ecological evaluation was conducted to identify the type and relative condition of the biological resources found on and to evaluate ecological characteristics of the property to identify remarkable resource attributes, and to briefly assess their conservation values in reference to local and regional contexts.

WestLand was retained by Resolution to prepare an Ecological Overview for approximately 1,295 hectares of land along the Lower San Pedro River near the Town of Mammoth. This ecological evaluation was conducted to identify the types, relative condition, and ecological value of the biological resources found on the Property, and to briefly assess their conservation values in the context of the San Pedro River watershed and the larger region.
