Determination of threatened species status under the Endangered Species Act of 1973 (Act), as amended, for the cactus ferruginous pygmy-owl (Glaucidium brasilianum cactorum), a bird subspecies found in Mexico, southern Arizona, and southern Texas.
Phase I consists of the hydrologic and geologic characterization of the study area. Also presented are the definition and quantification of groundwater recharge sources, pumpage, subsurface inflows and outflows, and recommendations to fill critical data deficiencies.
Groundwater monitoring in the upper Queen Creek and Devils Canyon watersheds was initiated by RCM in early 2004. The current RCM groundwater monitoring program includes 19 wells, boreholes or shafts. Based on results of hydrogeological characterization studies conducted to date, three principal aquifers have been identified. The purpose of the groundwater monitoring program is to provide hydrologic data for continued development and refinement of the conceptual hydrogeologic model for the ALT aquifer and adjacent aquifers in the study area that might be impacted by block-c
This report summarizes the meteorological, nitrogen dioxide (NO2), sulfur dioxide (SO2), ozone (O3), and particulate matter (PM) data collected at the Resolution Copper Project near Superior, Arizona for the first quarter, January 1-March 31, 2013.
An investigation of hydrogeologic conditions for the Superior Basin has been completed by Montgomery. The chief objective of the survey was to evaluate the cause of recent water level declines reported for some wells located within and adjacent to the Queen Creek corridor through the Superior Basin, as well as observed declines in discharge from Whitlow Ranch Dam.
Bird surveys were conducted in the vicinity of RCM's holdings, near Superior, Arizona. This report provides an inventory of the birds observed as well as a discussion of results from the data collection efforts.
Surveys were conducted for Morafka's desert tortoise (Gopherus morafkai, formerly G. agassizii, Sonoran population) within the Far West property located near Florence Junction, Arizona.
