The primary need for these realignments is due to the planned airport expansion at Tucson International Airport. The purpose of this report is to compare various alignment alternatives for the realignment on the basis of access, cost, right-of-way, and floodplain impacts.
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.
The purpose of this study is to (1) develop a fundamental understanding of the problems that exist, and (2) perform a cursory examination of possible management approaches identifying those that appear most plausible for further consideration.
Compiles information on plants and animals that are already recognized by the federal government as imperiled species, species which have been extirpated, and a much larger number of species that are in decline either locally or nationally. Descriptions of status, location, distribution, and habitat needs are presented for each species proposed. The report also considers vegetative communities, their history of decline and modification, and recommends priorities for their protection.
To facilitate discussion about which species might be considered for protection, a series of in-depth interviews were conducted with members of the local science community who have expertise in the areas of birds, fish, invertebrates, mammals, plants and plant communities, and reptiles and amphibians.
Review of existing ordinances, studies, and articles indicates that costs associated with making homes more accessible are minimal, yet jurisdictions in other parts of the United States have tended to limit the application of "visitability" ordinances to housing that is funded by a government entity.
