A fascinating and detailed look at sixteen communities in Pima County that experienced the boom and bust of the mining industry since the 1800s. Conveyed from a cultural historian's perspective, the stories of these communities are told with a goal of promoting preservation of the remnant railroads, schools, post offices, hotels, saloons, and other artifacts from this chapter of our history in Pima County.
Intended to provide the Board with a historical perspective of regional land use planning in Pima County, some of the tools and actions being used by other communities in growth management, and to provide a framework for future Board policy and direction.
The Arizona population of the cactus ferruginous pygmy-owl was listed as an endangered species under the Endangered Species Act in 1997. Historical records and recent surveys definitely show a decline of species. There is a wealth of historical information out there and it still trickles in every day.
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. However, over the past 150 years urban and agricultural expansion within the United States has reduced its population to a few isolated pockets of uncertain stability.
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.
Pima County contracted with Arizona Game and Fish Department to conduct telemetry analysis and gather information that would lead to effective conservation and recovery initiatives for the cactus ferruginous pygmy-owl. During 1997, banded birds were monitored. Beginning in 1998 and during 1999, pygmy-owls were radio-marked with backpack transmitters and followed on foot or by vehicle.
