Wildlife 20/20 provides broad strategic guidance for all department programs. It is intended to be a living document that conveys policy direction that the Arizona Game and Fish Commission has provided to the department to guide its work into the future. It will be complemented by additional plans designed to provide more specific direction, as needed.

The objective of this study was to evaluate the effect of typical chemical winter maintenance practices on Arizona Department of Transportation pavements. A review of previous studies on the effect of deicing/anti‐icing chemicals did not yield definitive recommendations, especially for DIAICs typically used by ADOT. Researchers conducted a laboratory study evaluating the effects of magnesium chloride, potassium chloride, sodium chloride, and distilled water on eight different open‐graded rubber‐modified asphalt concrete mixes using the boiling test. All experimental factors were found to be statistically significant, and the researchers provide recommendations on which DIAICs should be used for different binder and aggregate types.

Land Use and Traffic Congestion is an investigation into the links among land use, travel behavior, and traffic congestion. Researchers focused on four transportation corridors in the Phoenix area: three older neighborhoods with relatively mixed, higher density land use, and one suburban area with lower density but high traffic volumes. The analysis suggested that the higher density corridors exhibited less congestion due to the greater mix of uses, shorter trip lengths, more travel by transit and non-motorized modes, and the presence of a secondary street grid system.

This document contains laws related to wildlife in Arizona, from statehood in 1912 through 1962. This is a supplement to “Bringing Back the Game: Arizona Wildlife Management, 1912–1962,” a book of wildlife management history published by the Arizona Game and Fish Department in 2012.

Included are those bills passed by the Arizona State Legislature between 1912 and 1962, signed by the governor and incorporated as “Game and Fish Law” under the Arizona Revised Statutes. Other initiatives, referenda, and statutes pertaining to wildlife (including predatory and noxious animals) are also included, thereby providing an accessible resource for those interested in the history of Arizona’s wildlife laws.

This document is neither exhaustive nor complete. Some bills that are arcane or repetitive, or that served a housekeeping purpose, are not included. Some legislation is summarized with annotations by the author and not presented verbatim. The purpose is illustrative only and not intended to either replace the actual laws, or be taken as current law.

As part of the Long Term Pavement Performance (LTPP) Program, the Arizona Department of Transportation constructed eight Specific Pavement Studies 9 (SPS‐9) test sections on Interstate 10 near Phoenix is an overlay project and is accordingly given independent analysis and documentation in this report separate from Arizona SPS‐9B projects located on US 93, which were new construction and are documented in a separate report. The SPS‐9A project studied the effect of asphalt specification and mix designs on flexible pavements, specifically comparing Superpave binders with commonly used agency binders. Opened to traffic in 1995, the project was monitored at regular intervals until it was rehabilitated in 2005. Surface distress, profile, and deflection data collected throughout the life of the pavement were used to evaluate the performance of various flexible pavement design features, layer configurations, and thickness. This report documents the analyses conducted as well as practical findings and lessons learned that will be of interest to ADOT.

In Arizona, various nonnative trout have been stocked since the early 1900s, and trout angling remains an important component of the sportfishing industry. These nonnative rainbow trout may have contributed to the decline of Little Colorado spinedace. The overall purpose of the research was to define interactions so that impacts to both trout management and spinedace populations can be minimized. Our objectives covered 5 broad areas of potential interaction: habitat use, diet, predation, health, and distribution.

Although not Federally listed as threatened or endangered, the roundtail chub, also a sportfish in Arizona, is nearly extirpated from sections of the Verde and Salt river drainages. The purpose of this investigation, from March 1998 through March 2000, was to describe ecological requirements and population dynamics of roundtail chub. The objectives were to describe species composition, distribution and abundance, quantify habitat selection by different life stages, estimate population size, quantify movement and age and growth, and describe the reproductive capacity of roundtail chub.

Depending on wildlife species mobility and habitat requirements, we suspect that fire affect species differently, especially on sky islands where whole habitats could be reduced in size or destroyed. We evaluated effects of fire and vegetation destruction on low, moderate, and high mobility wildlife species. Specifically, we focused on the following species or groups: lizards; small mammals, primarily rodents; mid-sized carnivores, specifically gray fox, bobcats, and coyotes; and black bears.
