The Lower San Pedro Groundwater Basin (LSP) baseline groundwater quality study was conducted by the Arizona Department of Environmental Quality in 2000. Located in southeastern Arizona, this semiarid basin is drained by the San Pedro and Gila Rivers. The LSP is a rural landscape with scattered towns and two
extensive copper mining and processing operations. Groundwater from three aquifers (floodplain, unconfined basin-fill, and confined basin-fill or artesian) and fractured mountain hardrock is the principle source of water supply. For this study, 63 groundwater sites were sampled for inorganic constituents. In addition, fewer sites were also sampled for Volatile Organic Compounds (25), radiochemistry (19), radon (19), and pesticide (2) analyses. Eighteen (18) percent of sample sites had concentrations of at least one constituent that exceeded a health-based, Federal or State water-quality standard.

In March 1997, the Arizona Game and Fish Department and New Mexico Department of Game and Fish entered into a Conservation Agreement with other state, local, and federal cooperators, with voluntary participation by many private individuals, to conserve the jaguar (Panthera onca) along borderlands of Arizona and New Mexico and to stimulate parallel efforts in Mexico. The agencies believed that if strong partnerships could be developed under this approach, it would be a significant step forward in bringing local governments, private landowners, and nongovernmental organizations directly into jaguar management.

This document embraces two components. First, a Conservation Assessment describes the current status of the jaguar in the United States, and identifies and assesses risks to the jaguar in Arizona and New Mexico. The Assessment focuses the second component, the Conservation Strategy, on reducing or eliminating these threats in Arizona and New Mexico, which might allow for expansion of the range currently occupied by the Arizona subspecies, and thus contribute to promoting recovery of the species.
Information in this document comes primarily from the state level, an approach that considers regional variation and provides a complete habitat and species assessment.

The purpose of this plan is to provide information and recommendations to guide Arizona State Parks and other agencies in Arizona in their management of motorized and nonmotorized trail resources, and specifically to guide the distribution and expenditure of the Arizona Off-Highway Vehicle Recreation Fund, trails component of the Arizona Heritage Fund and the Federal Recreational Trails Program. This plan includes both motorized and nonmotorized trail information, public involvement results and recommendations for future actions regarding trails in Arizona.

Research into the sensitivity and vulnerability of urban water systems in Arizona reveals that managers are more concerned about factors such as population growth projections, economic trends, and revenue flows. Reliance on groundwater resources in many cases obscures recognition of any direct impact of precipitation on water supply. Given the low level of perceived climate risk among many providers interviewed for this study, it would seem unlikely that climate information would be needed. However, pockets of sensitivity and vulnerability to climatic impacts do exist in the four study areas covered in this study.

The study had three main goals: (1) to assess the vulnerability of groundwater-dependent agriculture to climate variability, (2) to identify historical and current processes of adaptation to the vagaries of climate in the region— these refer to both system wide adaptations and individual farmer’s adaptations, and, (3) to assess the use of and needs for seasonal climate forecast information in agricultural decision making. The report is targeted at institutional stakeholders (i.e., agricultural extension personnel), physical scientists (particularly climatologists), and policymakers (at the level of NOAA and other federal agencies). Specific recommendations are made to these groups in order to improve the delivery of seasonal forecasts, set research priorities, and inform public policy.

Conventional wisdom often views the urban water sector as being among the more sensitive sectors in the arid U.S. Southwest. To test this assumption, the Climate Assessment Project for the Southwest analyzed the water budgets of five Arizona cities to determine how severe the impacts would be from the deepest one-, five-, and ten-year droughts on record. Case study sites for the analysis included the Phoenix Active Management Area, Tucson Active Management Area, Santa Cruz Active Management Area, and the Benson and Sierra Vista subwatersheds of the San Pedro River.

The information presented here highlights the findings of a drought history study in support of the Governor's Drought Task Force activities, such as determining triggers for drought mitigation and response actions, based on observed hydroclimatic and other information. The material is intended to provide the relevant climatology background for non-specialists, and it is presented in a top ten or frequently asked question format. The questions and answers cover the major climate-related aspects of drought including long-term averages, seasonality, interannual and long-term spatial and temporal drought variations, extremes, and causes of climatic variability. The answers to each question include bulleted Quick Answers followed by a concise explanation of more detailed information. Example figures are presented within the text.
