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.

A number of significant positive and negative economic impacts could result from Pima County's SDCP and related programs, according to an analysis of existing research on large-scale conservation planning undertaken to provide a framework for community decision-making. This report offers no final verdict on the net economic impact of Pima County's current, ambitious initiatives in habitat conservation and growth management. However, it does provide a framework for future assessment and decision-making.

Saguaro National Park encompasses two geographically distinct areas: Rincon Mountain District and Tucson Mountain District. Of the two, only Rincon Park has significant riparian habitat due to Tanque Verde Ridge. The scope of this study includes Rincon Creek, its tributary riparian areas and Tanque Verde Creek riparian tributary areas within or immediately adjacent to the Park. Both of these creeks have riparian resources that will likely be impacted by proposed development adjacent to the Park boundaries.

Almost every state hopes to capitalize on the tremendous wealth and job creation that can be generated by high tech science research-and billions of public dollars are being spent. But everyone is just speculating about the lasting value of these investments. While traditional assessments of return on public investment in science and technology tend to track short-term impacts, such as salaries, patents, and licensing revenues, the main foundations for long-term development of a knowledge economy appear to rely on a number of less tangible accomplishments. For example: Connections - the networks that develop between researchers, entrepreneurs, and venture capitalists; Attention - the publicity generated by the research and its networks that attract businesses and talent to locate in a region; and Talent - the highly skilled workers that such research attracts and trains.

These three indicators of economic success-henceforth called the CAT measures-have yet to be quantified and applied in a useful manner. That is the purpose of this study. It will be conducted in three parts, each with a culminating report. The first part will analyze the FY03 science and technology research activities and results for ASU's Proposition 301 initiatives. The second will develop a methodology for quantifying and utilizing the Institute's CAT measures. The third will field test the CAT methodology on a selected aspect of ASU's Proposition 301-funded research, and analyze results to provide Arizona decision-makers with recommendations to guide future policy.

This publication updates the January 2004 study, New Returns on Investment in the Knowledge Economy: Proposition 301 at Arizona State University, FY 2003. Both works were launched by the report, Seeds of Prosperity: Public Investment in Science and Technology Research (2003), by Morrison Institute for Public Policy. Morrison Institute will periodically publish new material to keep you informed of the status of Proposition 301 investments at Arizona State University.
