The Drug Treatment Alternative to Prison (DTAP) Program enables drug addicted criminal defendants to plead guilty to an offense and then enter a residential, therapeutic community treatment system for three years as an alternative to a prison sentence. The Program begins with three months of in-patient, residential drug treatment followed by wraparound recovery support services managed by a resources specialist, including transitional housing, literacy services, higher education, job training and placement services, and counseling, accompanied by drug testing, probation monitoring, and regular court hearings.

Because the West Branch area has been left alone, it has a chance to recover and become a part of the larger Paseo de las Iglesias project, and a cornerstone of a more extensive effort at ecological restoration involving the mesic coorridors of Pima County, the Santa Cruz, Rillito, and Pantano.

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.
