Reports on the development of a reconnaissance level numerical groundwater model of the Davidson Canyon and Cienega Creek watersheds. Includes recommendations for data that must be collected prior to completing environmental analyses for the proposed project.
Develops the methods for using the National Land Cover Dataset to report change by jurisdictions and land ownership by utilizing an existing dataset. Local GIS-based measures of development based on tax assessor records do not provide direct measures of habitat loss.
The purpose of this study is to provide the U.S. Fish & Wildlife Service with an analysis that identifies anticipated impacts to each of the covered species and asks the question: How effectively will the County's mitigation lands include the specific habitats of covered species under the Multi-Species Conservation Plan?
This report examines how effectively Pima County’s natural open-space acquisitions have addressed priorities for conserving species’ habitats and landscape features identified in the Sonoran Desert Conservation Plan. The scope of this study is beyond the County's Multi-Species Conservation Plan, which is a subset of the overall Sonoran Desert Conservation Plan.
While we may view climate change issues as a more global or national problem, our unique Sonoran Desert ecosystem is a recognized global resource; hence climate change is an important consideration in how we manage and protect our fragile desert ecosystem. This discussion is designed to promote local awareness of how climate change may impact our resources.
The purpose of this report is to highlight lands acquired with 1997 and 2004 voter-approved bond funds, provide a historical record of Pima County’s land conservation efforts and consider how these properties contribute to Pima County’s long-term vision – the Sonoran Desert Conservation Plan. The report also provides a special feature on the evolution of conservation and land use planning in Pima County.
Pima County is now finalizing the long-awaited Multi-species Conservation Plan, which, if approved by the U.S. Fish and Wildlife Service, will streamline public-sector and private-sector development compliance with the Endangered Species Act while protecting endangered species and their habitats. In the coming months, the public will have a chance to comment on the MSCP through the U.S. Fish and Wildlife Service’s formal public comment process before it goes to the County Board of Supervisors for final adoption.This report reviews the history of the MSCP, its relationship with the award-winning Sonoran Desert Conservation Plan, what benefits the MSCP will bring to the community, and what obligations the County, developers, and the taxpayers will have over time. The report also highlights other benefits of conservation actions undertaken by Pima County, including economic, recreation, and health benefits.
Arizona Highways magazine is a powerful tool in highlighting, and presumably attracting tourists to, Arizona, and is particularly renowned for its photography. The publication currently has over one million readers and circulates in all 50 states and in two‐thirds of the world’s countries. In addition to the print publication, AHM utilizes electronic media, namely a website and Facebook Page, to reach customers and potential tourists. The Facebook Page enables users to engage in dialogue and interaction with each other—uploading photographs, sharing accounts of personal travel experiences, and reacting to specific AHM content—thereby personalizing their connection with the magazine and fellow users.
The purpose of this study is to build an econometric and demographic model of the Sun Corridor to forecast long-term economic and demographic conditions in the “megapolitan” region. To this end, the study examines the long-term economic and demographic forces that could affect economic development in the 3-county Sun Corridor megapolitan area that includes Maricopa, Pinal and Pima Counties. This information is used to develop a set of realistic economic/demographic scenarios to drive the forecasting model.
We conducted wildlife-highway relationships research from 2002–2006 along a 17-mile stretch of State
Route 260 in Arizona which is being reconstructed in five phases with 11 wildlife underpasses and 6
bridges. Reconstruction phasing allowed us to use a before-after-control experimental approach in our
research.
