Biological Resources

The documents listed below are Baseline Reports categorized topically as biological resources.

WestLand was retained to conduct surveys for the Western Yellow-billed Cuckoo (WYBC) in portions of Devils Canyon and Pinto Creek in Pinal and Gila counties, Arizona. The objective of the these surveys was to determine the presence and abundance of WYBC, based on habitat conditions considered most likely to support WYBC, in the vicinity of the Resolution Project.

WestLand was retained to conduct surveys for Arizona hedgehog cactus in conformance with the monitoring requirements of the Resolution Copper Mining Pre-feasibility Activities Plan of Operations and the Tonto National Forest's Finding of No Significant Impact. Pursuant to mitigation and monitoring measures prescribed by the PoO, survey of the Pre-Feasibility Activities Action Area for AHC is required every two years.

WestLand was retained to conduct surveys for Arizona hedgehog cactus (AHC) in the vicinity of East Plant, along portions of the existing Magma Mine Road, and along the proposed re-alignment of Magma Mine Road. AHC is federally listed as endangered without critical habitat throughout its entire range in Arizona.

As part of planning for proposed pre-feasibility studies, RCM retained WestLand to conduct an Arizona hedgehog cactus survey along areas proposed for pre-feasibility activities. This survey was conducted in accordance with established protocols and procedures as described in Section 2 of this report.

WestLand conducted surveys for the Western Yellow-billed Cuckoo in portions of Devils Canyon and Mineral Creek in the months of June through August 2011. These surveys were conducted in accordance with USFWS protocol. WestLand detected up to six individual WYBC in Mineral Creek, but there was only one unconfirmed sighting in Devils Canyon during the surveys.

WestLand was retained to conduct surveys for Arizona hedgehog cactus within the Resolution Pre-Feasibility Activities area in conformance with the monitoring required by the Resolution Copper Mining Pre-feasibility Activities Plan of Operations EA and the Forest Service's Biological Assessment and Evaluation.

WestLand was retained to conduct a survey for Arizona hedgehog cactus on the approximately 1,224-hectare Federal Parcel. The Parcel is on the Tonto National Forest east of the Town of Superior. Resolution proposes to obtain the Parcel by way of a land exchange. In support of this effort, WestLand has been conducting baseline resource investigations on the Parcel. The purpose of this survey was to identify existing locations AHC in accordance with established protocols and procedures.

WestLand was chosen by the Forest Service to act in the capacity of prime consultant provide environmental service in the analysis of the Resolution Pre-feasibility Activities Plan of Operations. The purpose of this report is to 1) compile Arizona hedgehog cactus survey data collected during RCM's preparation of the Pre-feasibility Activities Plan of Operations; and 2) compile previously completed survey data from the vicinity of the PAA that may inform the analysis of the effects of the Pre-feasibility Activities to AHC.

WestLand was retained to conduct a reptile and amphibian survey on the approximately 1,224-hectare Federal Parcel. Resolution proposes to obtain the Parcel by way of a land exchange. The purpose of this survey was to provide baseline data regarding reptile and amphibian populations on the Parcel. This survey effort focused on the USFWS threatened Chiricahua leopard frog and USFS Sensitive lowland leopard frog.

WestLand was retained to prepare an Ecological Overview for approximately 60.4 hectares in Maricopa County, Arizona. This ecological evaluation was conducted to identify the type and relative condition of the biological resources found and evaluate ecological characteristics of the property to identify remarkable resources attributes, and to briefly assess their conservation values in reference to local and regional contexts.
