Arizona State and Local Government Documents Collection
The State and Local Arizona Documents (SALAD) collection contains documents published by the State of Arizona, its Counties, incorporated Cities or Towns, or affiliated Councils of Government; documents produced under the auspices of a state or local agency, board, commission or department, including reports made to these units; and Salt River Project, a licensed municipality. ASU is a primary collector of state publications and makes a concerted effort to acquire and catalog most materials published by state and local governmental agencies.
The ASU Digital Repository provides access to digital SALAD publications, however the ASU Libraries’ non-digitized Arizona documents can be searched through the ASU Libraries Catalog. For additional assistance, Ask A Government Documents Librarian.
Publications issued by the Morrison Institute for Public Programs at Arizona State University are also available in PRISM, in the Morrison Institute for Public Policy - Publications Archive collection.

If one species had to be chosen to preserve and restore, perhaps it should be cottonwood. Cottonwood-willow forests, where they exist and are healthy, indicated the presence of a viable riparian area, which is in turn the key to conserving great proportions of our native species. A reflection of the dire status of our riparian systems is that the Sonoran cottonwood-willow and Sonoran mesquite-cottonwood forests.
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.
We have an opportunity now that we have not had in the past 25 years to develop some comprehensive planning so that we can continue to enjoy the environmental amenities that make it so nice to live in Tucson. These species include not only the common one that we live with on a day to day basis, but also some of the rare species that most of us are not lucky enough to see (but still care about preserving).
