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. 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.
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.
One of the most pressing growth related problems is the proliferation of wildcat subdividing, or lot splitting. It is generally defined as the proliferation of new residential parcels without the benefit of subdivision regulation. Often these areas are devoid of any basic infrastructure, standard environmental regulation, subdivision standards, or infrastructure requirements. This report addresses seven areas of concern.
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.
Provides an indication of why unregulated development offers so little benefit to the tax base by describing, briefly, the fiscal tax base impact of the unregulated lot split issue at the community and watershed level.
