Provides a brief review of the rules, listing history, and biological issues relevant to the status and protection of the pygmy-owl in Pima County. Land use in unincorporated northwest Pima County is analyzed to determine existing commitments and conservation opportunities, and in order to begin to answer the question of whether a general biological goal of conserving 80 percent of the pygmy-owl's habitat can be achieved.

Provides an overview of types of mitigation banking activities that have evolved from the Army Corps of Engineers wetlands banking. The discussion provides important distinctions between traditional practices in the area of mitigation banking and banking for endangered species purposes. The potential role of private sector in this market is described, as well as the roles of federal and local government participants.

The purpose of this paper is to provide background information on trends and possible future changes in urban structure and lifestyles important for planning the development of a parcel of Arizona state trust land known as Superstition Vistas (SV). This parcel, which is located just south of the Superstition Mountains in Pinal County, has an area of 275 square miles—enough land to provide housing for 900,000 new Phoenix metro-area residents at current population densities.

The aspects of future urban living discussed in this paper are those important for land-use planning—density, neighborhood design, transportation demand, etc. Very little attention will be given to the interior of homes. Also, since the SV parcel is currently undeveloped, emphasis will be placed on changes in urban structure that can be accomplished in greenfield developments rather than the in-fill of urban cores.
