Two additional sets of fact sheets that describe the threatened, endangered, and priority vulnerable species of Pima County. For each plant or animal there is a physical description and full color illustration. The habitat, range, diet, status, and history of each species is also outlined. These fact sheets will be widely distributed through the youth participation program.

Certain concepts related to the environment, particularly the conservation of biological and cultural resources, have been integrated into the Comprehensive Land Use Plan of Pima County. The attached cost model has been prepared to frame the issue of the estimated cost of Endangered Species Act compliance under the present planning model.
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.
Demonstrates that an effort to protect only listed species would lead to a reserve that was closer to the urbanizing areas of Tucson, and therefore more expensive. The Listed Species Reserve is also one that makes a call on more non-federal land. By limiting the focus of the reserve to listed species, the broader and long term benefits are lost, and trade-offs of high potential habitat are not based on such comprehensive biological principles.
Species re-establishment is the attempt to establish a species in an area which was once part of its historical range, but from which it has been extirpated or become extinct in the wild. Pima County and other agencies have proposed to re-establish species at a number of sites. Relevant laws and regulations governing re-establishment efforts are discussed. Case studies illustrate how previous efforts have been conducted and how the populations have fared.
The most complete version assembled of the story of the 56 plants and animals in Pima County that are in need of protection under the SDCP. Three years ago when discussions began about creating a multi-species protection plan, there was no comprehensive inventory of the resource base.
