Concern has been expressed that mesquite bosques are disappearing or diminishing in quality, and that the survival of the mesquite mouse is consequently threatened. This study, funded by a grant from the Arizona Heritage Fund to the Pima County Regional Flood Control District, investigated the current distribution of the mesquite mouse by reviewing historical records from museum specimens, examining existing potential habitat at historic locations of the species and elsewhere in the county, and conducting a live-trapping study at 19 sites representing a range of ecological communities with mesquite as a major component.
Each year, information is requested from cities, towns, private water companies, and water improvement districts in an effort to summarize and document water conservation activities implemented within Active Management Areas.
Groundwater resources of the Prescott AMA continue to be depleted on a regional basis, resulting in decreased groundwater storage in the aquifers of the area. In addition, natural groundwater discharge from the area has decreased with potential impacts on riparian areas and downstream users.
The model was developed as a tool to better understand the complex and interdependent stream-aquifer system, and to provide guidance for the management of regional water resources. Water management topics relevant to the Santa Cruz AMA include bi-national water issues and the reliability of water supplies. This model was primarily calibrated over the recent effluent-dominated groundwater flow regime (1997-2002) because of the availability of high quality head, flow and pumping data. Thus, some model boundary conditions calibrated over recent periods may not necessarily be representative of pre-effluent conditions.
