  • 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.

  • Coronado National Forest
    CORONADO NATIONAL FOREST FIRE MANAGEMENT PLAN Reviewed and Updated by _/s/ Chris Stetson ___________ Date __5/18/10 __________ Coronado Fire Management Plan Interagency Federal fire policy requires that every area with burnable vegetation must have a Fire Management Plan (FMP). This FMP provides information concerning the fire process for the Coronado National Forest and compiles guidance from existing sources such as but not limited to, the Coronado National Forest Land and Resource Management Plan (LRMP), national policy, and national and regional directives. The potential consequences to firefighter and public safety and welfare, natural and cultural resources, and values to be protected help determine the management response to wildfire. Firefighter and public safety are the first consideration and are always the priority during every response to wildfire. The following chapters discuss broad forest and specific Fire Management Unit (FMU) characteristics and guidance. Chapter 1 introduces the area covered by the FMP, includes a map of the Coronado National Forest, addresses the agencies involved, and states why the forest is developing the FMP. Chapter 2 establishes the link between higher-level planning documents, legislation, and policies and the actions described in FMP. Chapter 3 articulates specific goals, objectives, standards, guidelines, and/or desired future condition(s), as established in the forest’s LRMP, which apply to all the forest’s FMUs and those that are unique to the forest’s individual FMUs. Page 1 of 30 Coronado Fire Management Plan Chapter 1. INTRODUCTION The Coronado National Forest developed this FMP as a decision support tool to help fire personnel and decision makers determine the response to an unplanned ignition.

  • Connecting Mountain Islands and Desert Seas
    The Forgotten Flora of la Frontera Thomas R. Van Devender and Ana Lilia Reina Arizona-Sonora Desert Museum, Tucson, AZ Abstract—About 1,500 collections from within 100 kilometers of the Arizona border in Sonora yielded noteworthy records for 164 plants including 44 new species (12 non-native) for Sonora and 12 (six non-native) for Mexico, conservation species, and regional endemics. Many com- mon widespread species were poorly collected. Southern range extensions (120 species) were more numerous than northern extensions (20), although nine potentially occur in Arizona. Non-native species dispersed along highways and escaped from cultivation. The Turkish poppy (Glaucium corniculatum), established near Agua Prieta, may reach Arizona. African buffelgrass (Pennisetum ciliare) and Natal grass (Melinis repens) are rapidly expanding into new, higher elevation areas.

  • Correlation of Volcanic Rocks in Santa Cruz County, Arizona
    87 CORRELATION OF VOLCANIC ROCKS IN SANTA CRUZ COUNTY, ARIZONA By Otner J. Taylor A study of the volcanic rocks in Santa Cruz County, Arizona, has been tnade through cotnpilation of previous work together with new investigations. These cotnpilations indicate that there are tnany sitnilarities of sequence and structure in the volcanic rocks of the Atascosa Mountains, Tutnacacori Mountains, Santa Rita Mountains, Patagonia Mountains, and Mustang Mountains of Santa Cruz County. The volcanic rocks of the Tucson Mountains to the north of Pitna County also show sitnilarities to the volcanic rocks in the ranges of Santa Cruz County. Previous studies were tnade in the Atascosa and Tutnacacori Mountains by Webb and Coryell (1954). The regional geology of the Santa Rita and Patagonia Mountains was tnapped by Schraeder (1915) although tnany localized studies have since been tnade by various authors. The geology of the Mustang Mountains was tnapped by Bryant (1951). The Tucson Mountains have been studied principally by Brown (1939) and Kinnison (1958). A stratigraphic colutnn of the volcanic rocks of each range has been construc­ ted. These colutnns are shown on Plate 1. The generalized sequence in each case is: Cretaceous (?) andesite and rhyolite; Tertiary andesite, rhyolite, tuff, rhyolite-latite, and andesite; and Quaternary (?) basalt. The rocks were dated by using the principle of superposition as well as the following hypotheses: the rocks thought to be Cretaceous also are badly faulted and tilted and a pre-Laratnide age is suggested; the rocks thought to be Tertiary are thick and only gently tilted so that a post-Laratnide age is suggested; the upper andesites of this Tertiary sequence are not tilted, and they are probably post-Lower Miocene since they have structural and sequential sitnilarities with the andesites associated with the Lower Miocene Minetta beds and their probable equivalent, the Pantano fortnation; the rocks thought to be Quaternary are rela­ tively undisturbed and they overlie gravels and lake beds thought to be late Pliocene and Pleistocene.

  • Noteworthy Distributions and Additions in Southwestern Convolvulaceae
    NOTEWORTHY DISTRIBUTIONS AND ADDITIONS IN SOUTHWESTERN CONVOLVULACEAE Daniel F. Austin Arizona-Sonora Desert Museum Tucson, AZ 85734 [email protected] ABSTRACT Since 1998 when the Convolvulaceae was published for the Vascular Plants of Arizona, Calystegia sepium ssp. angulata Brummitt and Convolvulus simuans L. M. Perry have been added to the flora and another species, Jacquemontia agrestis (Choisy) Meisner, has been located that had not been found since 1945. Descriptions, keys, and discussions of these are given to place them in the flora. Additionally, these and Dichondra argentea Willdenow, D. brachypoda Wooton & Standley, D. sericea Swartz, Ipomoea aristolochiifolia (Kunth) G. Don, I. cardiophylla A. Gray, I. ×leucantha Jacquin, and I. thurberi A. Gray, with new noteworthy distributions records in the region, are discussed and mapped. All taxa documented by recent collections are illustrated to facilitate identification. DISTRIBUTION PATTERNS AND ADDITIONS TO THE ARIZONA FLORA Three notable disjunct records have been discovered within Arizona since the treatment of the Convolvulaceae was published for the state (Austin 1998a), Calystegia sepium ssp. angulata Brummitt, Convolvulus simulans L.M. Perry and Jacquemontia agrestis (Choisy) Meisner. Additionally, Ipomoea aristolochiifolia (Kunth) G. Don has been found just south of the border in Mexico. All of these are significant disjunctions in the family, but there are others that have been documented for years and little discussed. Although these are not the only disjunctions within the Convolvulaceae in the region, they are representative of floristic patterns in this and other families. The following discussion updates the known status of the Convolvulaceae in Arizona and compares several species to the floras from which they were derived.

  • K-Ar Geochronology and Geologic History of Southwestern Arizona and Adjacent Areas
    Arizona Geological Society Digest, Volume XII, 1980 201 K-Ar Geochronology and Geologic History of Southwestern Arizona and Adjacent Areas by 2 3 M. Shafiqullah , P.E. Damonl , D.J. Lynch l, S.J. Reynolds , WA. Rehrig , 4 and R.N. Raymond A bstract This paper presents K-Ar ages of 174 samples from 154 localities in southwestern Ari- zona and adjacent areas with a summary of the geologic history. Ages are given for many rock units that had been "dated" previously only by lithologic correlations. These ages establish the timing of the magmatic and tectonic events that created and deformed the rocks. We interpret the older Precambrian history of Arizona as the result of a long-enduring and evolving convergent continental margin with accretion to the southeast at the rate of 2 km/m.y. This process was terminated 1.4 b.y. ago by the intrusion of vast batholiths ex- tending in a northeasterly direction far beyond Arizona. Younger Precambrian rocks ac- cumulated in an epicontinental sea along the trend of the Cordilleran geosyncline. These rocks were intruded by extensive diabase sills that are best preserved in the central moun- tain region. There is no further record of Precambrian magmatism or sedimentation after intrusion of the diabase sills. Some Precambrian K-Ar dates have been reset by the thermal disturbance that accompanied these intrusions. K-Ar ages that fall within the Paleozoic are reset ages and there is no evidence for any Paleozoic magmatism in the region. K-Ar ages of most of the pre-Laramide Mesozoic igneous rocks in the region have been reset by Laramide magmatism but evidence has been found for Early to Late Jurassic magmatism.
