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.

Enhances the discussions of the feasibility of restoring flow paths at Aqua Caliente to a more natural state by providing information which allows us to better understand the wetland system that existed before periods of intervention.
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.
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.
Survey results for wetland plant communities of the Agua Caliente Park and nearby La Cebadilla property. The study also documented the presence or absence of Huachuca water umbel, a plant listed as endangered in Pima County. By studying the wetland plants of the La Cebadilla property, and through historic herbarium collections, the biologist found that several plants still present at La Cebadilla were known to be present at the Agua Caliente Ranch at the turn of the century.
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.
