Surficial Geology and Geologic Hazards of the Amado-Tubac area, Santa Cruz and Pima Counties, Arizona Amado and Tubac 7.5’ Quadrangles by Ann Youberg and Walter R. Helmick Arizona Geological Survey Digital Geologic Map 13 November, 2001 Arizona Geological Survey 416 W. Congress, Tucson, AZ 85701 Includes 17 pages of text and two 1:24,000 scale geologic maps Research supported by the Arizona Geological Survey and U.S. Geological Survey, National Cooperative Geologic Mapping Program, under USGS award number #00HQAG0149. INTRODUCTION This report and accompanying maps describe the surficial geology, geomorphology, and geologic hazards of the rapidly developing Amado-Tubac area, south of the Green Valley area. The mapping covers the Amado and Tubac 7 1/2’ quadrangles (Figure 1). The map area is in unincorporated Santa Cruz and southern Pima Counties. It includes much of the southern part of the upper Santa Cruz Valley, between the Santa Rita Mountains on the east and the Tumacacori Mountains on the west. There are several potentially conflicting land use issues in the area covered by these maps. The Santa Rita and Tumacacori mountain ranges are public lands owned by the U.S. Forest Service. Several large ranches are located within the mapping area and are interspersed with state trust lands. Urbanization has occurred, and continues to occur, along the Santa Cruz River and around the communities of Arivaca Junction, Tubac, and Rio Rico, just south of the map area. Many areas of the Santa Rita piedmont have been subdivided and prepared for development, although development remains sparse. This report is intended to enhance our understanding of the surficial geology of the Amado-Tubac area and to aid in assessing and understanding geologic hazards in this area. -

Tumacacori Potential Wilderness Area Evaluation [PW-05-03-D2-001]
Tumacacori Potential Wilderness Evaluation Report Tumacacori Potential Wilderness Area Evaluation [PW-05-03-D2-001] Area Overview Size and Location: The Tumacacori Potential Wilderness Area (PWA) encompasses 37,330 acres. This area is located in the Tumacacori and Atacosa Mountains, which are part of the Nogales Ranger District of the Coronado National Forest in southeastern Arizona (see Map 4 at the end of this document). The Tumacacori PWA is overlapped by 30,305 acres of the Tumacacori Inventoried Roadless Area, comprising 81 percent of the PWA. Vicinity, Surroundings and Access: The Tumacacori Potential Wilderness Area is approximately 50 miles southeast of Tucson, Arizona. The Tumacacori PWA is centrally located within the mountain range and encompasses an area from Sardina and Tumacacori Peaks at the northern end to Ruby Road at the southern end and from the El Paso Natural Gas Line on the eastern side to Arivaca Lake on its western side. The PWA is adjacent to the Pajarita Wilderness Area, Arivaca Lake and Peña Blanca Lake. Both Pena Blanca and Arivaca Lakes are managed by the Arizona Game and Fish Department. Interstate 19 (I-19) connects the Tucson metropolitan area to the City of Nogales and the incorporated community of Sahuarita. The unincorporated communities of Green Valley, Arivaca Junction-Amado, Tubac, Tumacacori-Carmen and Rio Rico, Arizona and Sonora, Mexico are within close proximity to the eastern side of the Tumacacori Mountains and the PWA. State Highway 289 provides access from I-19 across private and National Forest System lands into the Tumacacori Ecosystem Management Area to Peña Blanca Lake and Ruby Road (NFS Road 39). -

Arizona Forest Action Plan 2015 Status Report and Addendum A report on the strategic plan to address forest-related conditions, trends, threats, and opportunities as identified in the 2010 Arizona Forest Resource Assessment and Strategy. November 20, 2015 Arizona State Forestry Acknowledgements: Arizona State Forestry would like to thank the USDA Forest Service for their ongoing support of cooperative forestry and fire programs in the State of Arizona, and for specific funding to support creation of this report. We would also like to thank the many individuals and organizations who contributed to drafting the original 2010 Forest Resource Assessment and Resource Strategy (Arizona Forest Action Plan) and to the numerous organizations and individuals who provided input for this 2015 status report and addendum. Special thanks go to Arizona State Forestry staff who graciously contributed many hours to collect information and data from partner organizations – and to writing, editing, and proofreading this document. Jeff Whitney Arizona State Forester Granite Mountain Hotshots Memorial On the second anniversary of the Yarnell Hill Fire, the State of Arizona purchased 320 acres of land near the site where the 19 Granite Mountain Hotshots sacrificed their lives while battling one of the most devastating fires in Arizona’s history. This site is now the Granite Mountain Hotshots Memorial State Park. “This site will serve as a lasting memorial to the brave hotshots who gave their lives to protect their community,” said Governor Ducey. “While we can never truly repay our debt to these heroes, we can – and should – honor them every day. Arizona is proud to offer the public a space where we can pay tribute to them, their families and all of our firefighters and first responders for generations to come.” Arizona Forest Action Plan – 2015 Status Report and Addendum Background Contents The 2010 Forest Action Plan The development of Arizona’s Forest Resource Assessment and Strategy (now known as Arizona’s “Forest Action Plan”) was prompted by federal legislative requirements. -

Historical Fire Regime Patterns in the Southwestern United States Since AD 1700
This file was created by scanning the printed publication. Errors identified by the software have been corrected; however, some errors may remain. Historical Fire Regime Patterns in the Southwestern United States Since AD 1700 Thomas W. Swetnam and Christopher H. Baisan1 Abstract.-Fire-scar chronologies from a network of 63 sites in the South western United States are listed and described. These data characterize the natural range and variability of fire regimes from low elevation pine forests to higher elevation mixed-conifer forests since AD 1700. A general pattern of increasing length of intervals between low intensity surface fires was observed along gradients of low to high elevations, and from the rela tively drier pine sites to the wetter mixed-conifer sites. However, large vari ability in the measures of central tendency and higher moments of the fire interval distributions suggest that elevation and forest type were often weak determinants of fire frequency. Some of the variations in fire interval distri butions between similar elevation or forest types were probably due to unique site characteristics, such as landscape connectivity (Le., ability of fires to spread into the sites), and land-use history. Differences in the sizes of sampled areas and fire-scar collections among the sites also limited our ability to compare and interpret fire interval summary statistics. Comparison of both the fire-scar network data (1700 to 1900) and docu mentary records of area burned on all Southwestern Region National For ests (1920 to 1978) with a Palmer Drought Severity Index time series clearly shows the association between severe droughts and large fire years, and wet periods and small fire years. -

Threats to Cross-Border Wildlife Linkages in the Sky Islands Wildlands Network
Threats to Cross-Border Wildlife Linkages in the Sky Islands Wildlands Network Kim Vacariu Wildlands Project, Tucson, AZ Abstract—One of the greatest challenges facing conservationists in the Sky Islands region is finding a realistic means to maintain historic travel routes for wide-ranging species crossing the United States-Mexico border. This challenge is made difficult due to the ongoing efforts by the Federal government to install additional security infrastructure to stem the flood of undocumented immigrants now entering southern Arizona. Existing and proposed fencing, solid steel walls, all- night stadium lighting, vehicle barriers, an immense network of roads, a 24-hour flow of patrol vehicles, and low-level aircraft overflights are creating an impenetrable barrier to trans-border wildlife movement. Creative solutions are needed now. northern Mexico, and the Sky Islands of southeastern Arizona Introduction were maintained. In 2000, the Wildlands Project and regional partner groups, The SIWN CP identified numerous threats to a healthy including the Sky Island Alliance, published a conservation landscape in the Sky Islands, including fragmentation of plan covering more than 10 million acres of valuable wildlife habitat by roads, fences, and subdivisions; loss or extirpation habitat in the Sky Islands ecoregion of southeast Arizona and of numerous species; loss of natural disturbance regimes such southwest New Mexico.
