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.

Apache trout is a federally threatened salmonid native to headwaters of the Little Colorado, Black, and White rivers in east-central Arizona. Decline of Apache trout to threatened status was attributed to over-fishing, habitat degradation and negative interactions (predation, competition and hybridization) with introduced nonnative salmonids. Although over-fishing is no longer considered a threat, habitat degradation and negative interactions with nonnative salmonids continue to threaten Apache trout, and it is towards these threats that recovery actions are directed. While barrier construction began in 1979 and livestock exclusion began in the mid-1980s, the efficacy of these recovery actions at increasing Apache trout abundance and improving habitat condition had not been evaluated. We therefore initiated a study to evaluate the efficacy of riparian fencing and barriers.

The goal of our study was to develop information to help manage aquatic plants in Arizona’s reservoirs to benefit sport fish management activities and angler access. To attain this goal we surveyed aquatic plants in reservoirs throughout Arizona and evaluated if the Arizona Game and Fish Department’s aquatic weed harvesting program was benefiting the fisheries program. Aquatic plant harvesting is probably a worthwhile endeavor to improve angler access and keep our angling customers satisfied. However, we strongly recommend that more effective decontamination procedures be implemented to limit the spread of invasive species

This special topic report examines the prevalence and characteristics of co-occurring substance abuse and mental health problems among juvenile detainees in Maricopa County. The findings come from the Co-occurring Disorder Addendum used during 2007. The findings reveal that almost 30 percent of juvenile detainees were at risk for a co-occurring disorder, and face significantly greater difficulties across a number of critical factors, including incarceration, homelessness, and victimization.

This special topic report examines the prevalence and characteristics of co-occurring substance abuse and mental health problems among adult arrestees in Maricopa County. The findings suggest that more than 28 percent of adult arrestees in Maricopa County are at risk for a co-occurring disorder, and they face significantly greater difficulties across a number of critical factors, including incarceration, homelessness, and victimization. Understanding the prevalence and particular characteristics of the dual-diagnosed arrestee population in Maricopa County is an important part of assessing demands on behavioral health and substance use treatment resources. Additionally, examining some of the current defining characteristics of this population relative to arrestees not dually diagnosed can serve as an indicator of future demand.

Arizona’s public behavioral health care system, which serves some 150,000 mentally ill and vulnerable state residents, is wrestling with a number of urgent challenges. In addition to budget cuts resulting from the current economic crisis, and the demands of a 28-year-old class-action lawsuit, the system has been repeatedly criticized in several areas, including for inadequate staff, data, housing support, and crisis services. On July 22, a panel of professionals who play key roles in the system discussed these and other issues before some 300 behavioral health providers, supervisors, and policymakers at the annual Summer Institute hosted by Arizona State University’s Center for Applied Behavioral Health Policy. This paper provides an abbreviated report of that discussion, which was partially designed and moderated by ASU’s Morrison Institute for Public Policy.

Severe and widespread budget cuts in behavioral health and substance abuse services for lower-income Arizonans who don’t qualify for AHCCCS have already taken effect across the state. Even before these cuts were implemented, it was clear that the publicly-supported behavioral health system in our state was not adequately serving many Arizonans who needed mental health or substance use disorder treatment. This paper represents an effort by Arizona State University’s Centers for Applied Behavioral Health Policy and the Morrison Institute for Public Policy to promote and enrich Arizona’s public dialogue about these problems and potential solutions.
