Most of the owls until just the last couple of years have been found in residential areas in northwest Tucson. It take a lot of cooperation on the parts of private residents to help get the work done. These are incredible little birds that fill an interesting role in the environment since they are more diurnal versus nocturnal. Our objective is to gather as much information as fast as possible to feed into the process to make this County plan based on the best available science that we have.
The historical range of the ferruginous pygmy-owl included areas of southern Arizona, southern Texas extending south along both coasts in Mexico, through Central America into the southernmost population in Argentina.

The Arizona population of the cactus ferruginous pygmy-owl was listed as an endangered species under the Endangered Species Act in 1997.

Elements of the comprehensive plan now include planning for water resources that must address the currently available surface water, groundwater, and effluent supplies and provide an analysis of how the future growth projected in the county plan will be adequately served by the legally and physically available water supply. This is the first study to be issued as part of the Water Resources Element and identifies a number of measures that can be taken to conserve water, including measures that can be taken by Pima County in the form of ordinance adoption.
