DEPARTMENT OF THE INTERIOR U.S. FISH AND WILDLIFE SERVICE REGION 2 DIVISION OF ENVIRONMENTAL CONTAMINANTS CONTAMINANTS IN BIGHORN SHEEP ON THE KOFA NATIONAL WIL DLIFE REFUGE, 2000-2001 By Carrie H. Marr, Anthony L. Velasco1, and Ron Kearns2 U.S. Fish and Wildlife Service Arizona Ecological Services Office 2321 W. Royal Palm Road, Suite 103 Phoenix, Arizona 85021 August 2004 2 ABSTRACT Soils of abandoned mines on the Kofa National Wildlife Refuge (KNWR) are contaminated with arsenic, barium, mercury, manganese, lead, and zinc. Previous studies have shown that trace element and metal concentrations in bats were elevated above threshold concentrations. High trace element and metal concentrations in bats suggested that bighorn sheep also may be exposed to these contaminants when using abandoned mines as resting areas. We found evidence of bighorn sheep use, bighorn sheep carcasses, and scat in several abandoned mines. To determine whether bighorn sheep are exposed to, and are accumulating hazardous levels of metals while using abandoned mines, we collected soil samples, as well as scat and bone samples when available. We compared mine soil concentrations to Arizona non-residential clean up levels. Hazard quotients were elevated in several mines and elevated for manganese in one Sheep Tank Mine sample. We analyzed bighorn sheep tissues for trace elements. We obtained blood, liver, and bone samples from hunter-harvested bighorn in 2000 and 2001. Arizona Game and Fish Department also collected blood from bighorn during a translocation operation in 2001. Iron and magnesium were elevated in tissues compared to reference literature concentrations in other species. Most often, domestic sheep baseline levels were used for comparison because of limited available data for bighorn sheep. -

Clear-Water Tributaries of the Colorado River in the Grand Canyon, Arizona: Stream Ecology and the Potential Impacts of Managed Flow by René E
Clear-water tributaries of the Colorado River in the Grand Canyon, Arizona: stream ecology and the potential impacts of managed flow by René E. Henery ABSTRACT Heightened attention to the sediment budget for the Colorado River systerm in Grand Canyon Arizona, and the importance of the turbid tributaries for delivering sediment has resulted in the clear-water tributaries being overlooked by scientists and managers alike. Existing research suggests that clear-water tributaries are remnant ecosystems, offering unique biotic communities and natural flow patterns. These highly productive environments provide important spawning, rearing and foraging habitat for native fishes. Additionally, clear water tributaries provide both fish and birds with refuge from high flows and turbid conditions in the Colorado River. Current flow management in the Grand Canyon including beach building managed floods and daily flow oscillations targeting the trout population and invasive vegetation has created intense disturbance in the Colorado mainstem. This unprecedented level of disturbance in the mainstem has the potential to disrupt tributary ecology and increase pressures on native fishes. Among the most likely and potentially devastating of these pressures is the colonization of tributaries by predatory non-native species. Through focused conservation and management tributaries could play an important role in the protection of the Grand Canyon’s native fishes. INTRODUCTION More than 490 ephemeral and 40 perennial tributaries join the Colorado River in the 425 km stretch between Glen Canyon Dam and Lake Mead. Of the perennial tributaries in the Grand Canyon, only a small number including the Paria River, the Little Colorado River and Kanab Creek drain large watersheds and deliver large quantities of sediment to the Colorado River mainstem (Oberlin et al. -
Orocopia Schist in the Northern Plomosa Mountains, West-Central Arizona: a Laramide Subduction Complex Exhumed in a Miocene Metamorphic Core Complex
RESEARCH Orocopia Schist in the northern Plomosa Mountains, west-central Arizona: A Laramide subduction complex exhumed in a Miocene metamorphic core complex E.D. Strickland1, J.S. Singleton1, and G.B. Haxel2,3 1DEPARTMENT OF GEOSCIENCES, COLORADO STATE UNIVERSITY, FORT COLLINS, COLORADO 80523, USA 2U.S. GEOLOGICAL SURVEY, FLAGSTAFF, ARIZONA 86001, USA 3GEOLOGY PROGRAM, SCHOOL OF EARTH SCIENCES AND ENVIRONMENTAL SUSTAINABILITY, NORTHERN ARIZONA UNIVERSITY, FLAGSTAFF, ARIZONA 86011, USA ABSTRACT We document field relationships, petrography, and geochemistry of a newly identified exposure of Orocopia Schist, a Laramide subduction complex, in the northern Plomosa Mountains metamorphic core complex of west-central Arizona (USA). This core complex is character- ized by pervasive mylonitic fabrics associated with early Miocene intrusions. The quartzofeldspathic Orocopia Schist records top-to-the-NE mylonitization throughout its entire ~2–3 km structural thickness and 10 km2 of exposure in the footwall of the top-to-the-NE Plomosa detachment fault. The schist of the northern Plomosa Mountains locally contains graphitic plagioclase poikiloblasts and scattered coarse- grained actinolitite pods, both of which are characteristic of the Orocopia and related schists. Actinolitite pods are high in Mg, Ni, and Cr, and are interpreted as metasomatized peridotite—an association observed in Orocopia Schist at nearby Cemetery Ridge. A 3.5-km-long unit of amphibolite with minor interlayered ferromanganiferous quartzite is localized along a SE-dipping contact between the Orocopia Schist and gneiss. Based on their lithologic and geochemical characteristics, we interpret the amphibolite and quartzite as metabasalt and meta chert, respectively. The top of the Orocopia Schist is only ~3–4 km below a ca. -
FISH of the COLORADO RIVER Colorado River and Tributaries Between Glen Canyon Dam and Lake Mead
FISH OF THE COLORADO RIVER Colorado River and tributaries between Glen Canyon Dam and Lake Mead ON-LINE TRAINING: DRAFT Outline: • Colorado River • Glen Canyon Dam Adaptive Management Program (GCDAMP) • Native Fishes • Common Non-Native Fishes • Rare Non-Native Fishes • Standardized Sampling Protocol Colorado River: • The Colorado River through Grand Canyon historically hosted one of the most distinct fish assemblages in North America (lowest diversity, highest endemism) • Aquatic habitat was variable ▫ Large spring floods ▫ Cold winter temperatures ▫ Warm summer temperatures ▫ Heavy silt load • Today ▫ Stable flow releases ▫ Cooler temperatures ▫ Predation Overview: • The Glen Canyon Dam Adaptive Management Program was established in 1997 to address downstream ecosystem impacts from operation of Glen Canyon Dam and to provide research and monitoring of downstream resources. Area of Interest: from Glen Canyon Dam to Lake Mead Glen Canyon Dam Adaptive Management Program (Fish) Goals: • Maintain or attain viable populations of existing native fish, eliminate risk of extinction from humpback chub and razorback sucker, and prevent adverse modification to their critical habitat. • Maintain a naturally reproducing population of rainbow trout above the Paria River, to the extent practicable and consistent with the maintenance of viable populations of native fish. Course Purpose: • The purpose of this training course “Fish of the Colorado River” is to provide a general overview of fish located within the Colorado River below Glen Canyon Dam downstream to Lake Mead and linked directly to the GCDAMP. • Also included are brief explanations of management concerns related to the native fish species, as well as species locations. Native Fishes: Colorado River and tributaries between Glen Canyon Dam and Lake Mead Bluehead Sucker • Scientific name: Catostomus discobolus • Status: Species of Special Concern (conservation status may be at risk) • Description: Streamlined with small scales.
