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.
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?
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.
Provides individuals and companies anticipating mineral exploration or mining in Arizona with a clear picture of the permitting process. This document is an honest attempt to present all the permits that may be required by a mining operator in Arizona.
This directory contains a listing of Arizona-registered consultants for the following mining related disciplines: assayers, geological engineers, geologists, geophysical engineers, metallurgical engineers, and mining engineers.

This report, a companion to Open File Report 90-5, Publications of the department of Mines and Mineral Resources from 1939 to 1990, is a serial listing of the publications of the Department from September 1990 to December 2004.
This article studies the characteristics of modern Arizona mining scams or nontraditional mining projects and describes a number of examples. The purported mines or properties were located in Arizona, or the schemes had other substantial ties to the state.
Chronicles how the intention to conserve a relic population of Gila topminnow under current resource conditions is generally insufficient. We have let the resource base degrade too far to expect project and site specific responses to stem losses, much less lead to recovery. The Gila topminnow was considered to be among the most common of fishes in the Santa Cruz River system in the early 1940s. Three decades later is was considered endangered; and in another three decades time, its recovery is not foreseeable, given the piecemeal approach to protection efforts.
