The spread of invasive species creates serious environmental problems as well as economic hazards for residents and will hamper implementation of parts of the SDCP.
The final version of the report issued in early 2001. County staff responded in writing to clarify misunderstandings in the letter by Tucson Water. Pima County will continue to assess and look for ways to contribute to the protection of the resources in the Tanque Verde area.
In the early 1990s, a study of the Tanque Verde Creek by Dr. Julie Stromberg and others described the relationship between the depth to groundwater and the health of the mesquite woodland habitat in the area. This report revisits the Stromberg study to describe variations in groundwater levels since the report was completed early last decade. They identified around 3,000 acres of riparian vegetation in the Tanque Verde-Agua Caliente shallow groundwater zone.
An assessment of the problems that are presented by non-native and introduced species in maintaining native species and natural systems.

A companion to the study issued on July 5, 2000 entitled 'Cactus Ferruginous Pygmy-Owl Investigations in Pima County.' The major objective was to determine whether pygmy-owls chose nest sites or perch trees with characteristics that differ from other available sites within a nesting territory.
Arivaca, located on the southern border of Pima County, is one of the few remaining riparian areas in southern Arizona.

Summarizes the attached resource reports that have been submitted so far to help develop the SDCP within the watershed planning area of the Altar Valley.

The study finds that if minority families owned homes at the same rate as whites of a similar age and income, there would be an additional 3.5 million homeowners today. A major factor contributing to this gap is that minority and lower income famimlies experience continuing, and in many cases growing, inequalities in obtaining the financing necessary to purchase a home.
