The Muddy Creek watershed, part of the Upper Colorado River watershed, is a semi-arid catchment in a sagebrush steppe ecosystem. A synoptic watershed assessment was conducted in 2010 to identify areas within the watershed that are more susceptible to mobilization of trace elements that occur in soils forming on marine shale. Samples of soil, stream sediment, and water were collected and assayed for major elements and a suite of trace elements. Formation waters discharged from two wells within the watershed were sampled in 2011 to evaluate their potential contribution of organic carbon, nitrogen (N) species, and trace elements to surface waters. In FY2012, analyses of the soil, rock, and water samples collected...

Limits on the time and financial resources available for monitoring efforts, coupled with the complexities of natural resources and stakeholders, are challenges in resource monitoring. To help address these and related challenges, the USGS Monitoring Team (MT) has linked conceptual monitoring specialists with habitat and wildlife biologists to inform and develop creative, scientifically defensible approaches for monitoring the status and trends of populations and habitats across the WLCI region. This collaboration has led to spatially balanced monitoring designs that will make it possible to interpret conditions across the WLCI region and a mechanism for integrating species’ distributions and population responses...

Regional-scale studies, such as those being conducted for the WLCI, are well suited for the use of remote-sensing techniques. Derivative products from remote-sensing instruments, such as Landsat, have been used successfully for decades in studies of geology, vegetation, environmental change, and many other types of scientific research. The continuous coverage of Landsat data since 1972 makes it possible to establish baseline conditions in areas affected by renewable and nonrenewable energy development. In this study, various Landsat datasets are being used to map current and pre-development conditions in the WLCI study area for a selected set of scientific interests. Landsat scenes have been mosaicked to produce...

The USGS and University of Minnesota collaborators used acoustical and ultrasonic recorders to monitor flight notes of birds and calls emitted by bats flying at low elevations. Recorders were deployed in conjunction with ongoing fatality searches at wind facilities and at sites with a variety of landscape features. Objectives are to determine whether the recorders can be used to compare low-elevation flight activity among sites, and to relate recorder results to numbers of dead birds and bats found at wind facilities. The U.S. Fish and Wildlife Service joined the partnership to deploy the recorders at numerous locations along the shores of several Great Lakes to estimate low-elevation flight activity of birds and...

Description of Work Initial tests of a variety of chemical stimuli identified a strong response to the algal food attractant. Field testing of chemical stimulants based on algae will seek to identify potent mixtures based on persistence and duration of attraction. These studies will include consideration of component chemicals such as amino acids produced by algae that enhance the attractiveness of the stimulus, based on carp smell and taste senses. Means of providing a sustained release of the stimulant will be explored through tests of various media. Tests will be conducted to confirm the possibility that carp can be conditioned to feeding stations that can be used to facilitate their capture. Relevance & Impact...

Description of Work Benthos (benthic invertebrate) and plankton (phytoplankton/zooplankton) communities in Wisconsin's four Lake Michigan Areas of Concern (AOCs; Menominee River, Lower Green Bay and Fox River, Sheboygan River, and Milwaukee Estuary) and six non-AOCs will be quantified. The inclusion of non-AOC sites will allow comparison of AOC sites to relatively-unimpacted or less-impacted control sites with natural physical and chemical characteristics that are as close as possible to that of the AOCs. The community data within and between the AOCs and non-AOCs will be analyzed. This project is a cooperative agreement between the Wisconsin Department of Natural Resources (WDNR) and the US Geological Survey (USGS)....

Description of Work USGS will conduct seasonal sampling of benthic invertebrates, zooplankton, prey fish, and their diets to complement the seasonal lower trophic level sampling by EPA. A point of emphasis is describing the vertical distribution of planktivores and their zooplankton prey, to fill a knowledge gap on these predator/prey interactions. These data will provide a more holistic understanding of how invasive-driven, food-web changes could be altering energy available to sport fishes in the Great Lakes and used to build bioenergetics models that can evaluate whether zooplankton dynamics are being driven by limited resources or excessive predation. Understanding the key drivers of zooplankton will provide...

In the WLCI region, the quality and condition of sagebrush steppe is a concern given the extent of rangewide land-use change, habitat conversion, and rapid energy development in sagebrush systems. Three migratory songbird species are considered near-obligates of sagebrush shrublands: Brewer’s and sagebrush sparrows and sage thrasher, all of which are designated Species of Great Conservation Need in Wyoming (Wyoming Game and Fish Department, 2010) and nest in Green River Basin. In collaboration with the WGFD, we initiated this multiphase project to address the WLCI management need to identify the condition and distribution of sagebrush songbird habitats and key drivers of change in those habitats. In Phase I (2008...

Muddy Creek, a tributary to the Little Snake River, is a semi-arid catchment that drains about 1,200 mi2 in south-central Wyoming. The drainage basin is characterized as a sagebrush steppe ecosystem. The area is undergoing energy exploration and development, including conventional natural gas wells and coalbed natural gas wells. Geologic formations that underlie the drainage basin include soluble marine shales, which are a natural source of dissolved solids (for example, sodium, chloride, and sulfate) and Se. As a result, the water quality of Muddy Creek is naturally high in dissolved constituents, including Se. The WDEQ has listed chloride and Se as impairments to aquatic life for Muddy Creek. Dissolved solids...

USFWS, Region 8, Reno, Nevada desired to acquire LIDAR along the East and West forks of the Walker River, Nevada. Their goal is develop an accurate digital elevation model (DEM) within the river channel and into the uplands approximately 500 meters on each side. The goal is to use the DEM to assist in targeting restoration efforts for Lahonton Cutthroat as well as characterize the riparian vegetation and associated nearby uplands.

The Army Corps of Engineers recently initiated a program to create and improve emergent sandbar habitat (hereafter ESH) throughout the upper Missouri River system. This program has resulted in creation of three sandbar complexes and implementation of vegetation control on existing sandbars in the Gavins Point reach during 2004 and 2005. In order to meet habitat acreage goals in the Biological Opinion, the Corps has developed extensive plans for numerous additional habitat creation and improvement projects throughout the upper Missouri River system. Given the momentum of current habitat creation and improvement projects and their associated costs, it is imperative that the capacity be available to quantify changes...

The elk herd that currently inhabits the South Unit of Theodore Roosevelt National Park (THRO) originated in 1985, when the National Park Service (NPS) translocated 47 animals from Wind Cave National Park. The reintroduction was undertaken to restore a culturally and ecologically important species to its native range, but was initially opposed by the State of North Dakota because area landowners feared that elk might escape the park and cause damage to crops and fences. To alleviate this concern, the NPS agreed to regulate elk numbers at levels that “do not unduly interfere” with livestock grazing or agriculture, and to generally resolve conflicts in favor of existing land uses (Memorandum of Understanding 1540-5-0001)....

We are living in a period of unprecedented global change where even the most remote areas of the planet are influenced by the activities of man. Modern landscapes have been highly modified to accommodate a growing human population that is forecast to peak at 9.1 billion by 2050. Over this past century, human reliance on goods and services from ecosystems has greatly increased and sustainability of our modern and intensively managed ecosystems has been a topic of serious national and international concern. Not surprisingly, sustainability of ecosystems has become an explicitly stated goal of many agencies and, in some cases, has been legislatively mandated to ensure the provisioning of resources for future generations....

1) Improve predictions of streamflow at ungaged basins, and 2) understanding the causes of streamflow changes due to human changes to the environment, and 3) establish biological-flow relations.
Quantitative understanding of groundwater and gas-rich fluid- and thermodynamics in volcanic areas is important for several reasons: 1) as a major source of hazard such as propellant in steam-driven explosions, lubricant in mudflows, and transport agent for toxic constituents such as arsenic and mercury that are dissolved from fresh volcanic rock, 2) groundwater pressure, temperature and chemical changes might signal one of the earliest warnings of volcanic unrest, 3) exploration and mining of geothermal energy and mineral deposits. Many of the geochemical, geodetic, and seismic signals measured at the ground surface as part of the volcano monitoring strategies have hydrothermal origins or magmatic origins modulated...

Piping plovers ( Charadrius melodus) are a Federally threatened shorebird that breeds in three principal habitat types in the Northern Great Plains (NGP): reservoir shorelines, alkali wetlands (including managed impoundments on refuges and isolated wetlands on private lands), and midchannel emergent sandbars on major river systems in the Missouri River Basin. However, the long-term concurrent mark-recapture programs on the Missouri River have thus far been limited to the lower Missouri and Platte rivers, a region that represents only one of the three primary habitat types (e.g. midchannel emergent sandbars). In contrast, the northern Missouri River system (e.g. Lake Oahe north to the Garrison dam, Lake Sakakawea,...
