The Colorado River is the dominant water source for the southwestern United States, crossing through seven states before reaching Mexico. The river supplies water to approximately 36 million people, irrigates nearly six million acres of farmland within and beyond the basin, and contributes an estimated 26 billion dollars each year to the region’s recreational economy. Yet the Colorado River’s water supply is already fully allocated, meaning that the economic and environmental health of the region is closely tied to the river’s streamflow. Climate projections for the Southwest show a future marked by chronic drought and substantial reductions in streamflow. The region has already been impacted by climate change,...

This project links climate, hydrological, and ecological changes over the next 30 years in a Great Basin watershed. In recent years, climate variability on annual and decadal time scales has been recognized as greater than commonly perceived with increasing impacts on ecosystems and available water resources. Changes in vegetation distribution, composition and productivity resulting from climate change affect plant water use, which in turn can alter stream flow, groundwater and eventually available water resources. To better understand these links, project researchers implemented two computer-based numeric models in the Cleve Creek watershed in the Schell Creek Range, east of Ely, Nevada. The application of the...

The USGS Central Region Energy Team assesses oil and gas resources of the United States. The onshore and State water areas of the United States comprise 71 provinces. Within these provinces, Total Petroleum Systems are defined and Assessment Units are defined and assessed. Each of these provinces is defined geologically, and most province boundaries are defined by major geologic changes. The Eastern Great Basin Province is located in western Utah, eastern Nevada, southern Idaho, and the northwest corner of Arizona, encompassing all or parts of Mohave County in Arizona, Power, Bannock, Cassia, Oneida, and Franklin Counties in Idaho, Elko, Eureka, Lander, White Pine, Nye, Lincoln, and Clark Counties in Nevada, and...
The Total Petroleum System is used in the National Assessment Project and incorporates the Assessment Unit, which is the fundamental geologic unit used for the assessment of undiscovered oil and gas resources. The Total Petroleum System is shown here as a geographic boundary defined and mapped by the geologist responsible for the province and incorporates not only the set of known or postulated oil and (or) gas accumulations, but also the geologic interpretation of the essential elements and processes within the petroleum system that relate to source, generation, migration, accumulation, and trapping of the discovered and undiscovered petroleum resource(s).
Cell maps for each oil and gas assessment unit were created by the USGS as a method for illustrating the degree of exploration, type of production, and distribution of production in an assessment unit or province. Each cell represents a quarter-mile square of the land surface, and the cells are coded to represent whether the wells included within the cell are predominantly oil-producing, gas-producing, both oil and gas-producing, dry, or the type of production of the wells located within the cell is unknown. The well information was initially retrieved from the IHS Energy Group, PI/Dwights PLUS Well Data on CD-ROM, which is a proprietary, commercial database containing information for most oil and gas wells in the...
Western U.S. rangelands have been quantified as six fractional cover (0-100%) components over the Landsat archive (1985-2018) at 30-m resolution, termed the “Back-in-Time” (BIT) dataset. Robust validation through space and time is needed to quantify product accuracy. We leverage field data observed concurrently with HRS imagery over multiple years and locations in the Western U.S. to dramatically expand the spatial extent and sample size of validation analysis relative to a direct comparison to field observations and to previous work. We compare HRS and BIT data in the corresponding space and time. Our objectives were to evaluate the temporal and spatio-temporal relationships between HRS and BIT data, and to compare...

The CED has had success in tracking implementation of conservation actions for terrestrial at-risk species, and can develop systems to monitor the implementation of and inform effectiveness of conservation, restoration, and recovery actions for aquatic at-risk species as well. Pursuant to the Regional Priority Goal to Recover listed cutthroat trout and improve or maintain the conservation status of other cutthroat trout and Arctic grayling populations, the CED Team proposes to develop a framework and modules that displays important resource layers/values important for biological planning and conservation design in addition to collecting information about recovery actions that may improve habitat and/or reduce threats...

Fire in the western U.S. poses one of the greatest threats to human and ecological communities alike. In fact, fire management is the largest single expenditure of land management funds on federal lands. Now, climate change is altering wildfire patterns. Climate change in the West is creating warmer and drier conditions, resulting in an increase in the amount of dead vegetation available to fuel fires. This project sought to assess the vulnerability of forests in the southwestern U.S. to climate change and wildfire, in order to understand how these ecosystems might become altered as a result. Researchers (a) examined how climate change impacts wildfires in the region, to better understand fire risk; (b) identified...

Native Americans are one of the most vulnerable populations to climate change in the United States because of their reliance upon the natural environment for food, livelihood, and cultural traditions. In the Southwest, where the temperature and precipitation changes from climate change are expected to be particularly severe, tribal communities may be especially vulnerable. Through this project, researchers sought to better understand the climate change threats facing the Pyramid Lake Paiute Tribe of northwestern Nevada. Researchers found that the Tribe’s vulnerability to climate change stems from its dependence on Pyramid Lake, which may experience reduced water supply in the future. This will potentially have negative...

The Conservation Efforts Database (CED) is in the process of collecting information related to conservation efforts implemented in the sagebrush biome. This data will predominantly covers the time from 2009-2018. It is our hope to utilize this information and partner with USGS to investigate if/how these efforts are related to greater sage-grouse population trends being developed as part of a larger Population Monitoring Framework that FWS is involved with. Results of this evaluation would help inform which populations/areas may be receiving a larger conservation benefit from action implemented as well as if changes in trends are related to conservation efforts or other environmental factors. This effort is in support...

Biodiversity is declining worldwide, and this trend could potentially become more severe as climate conditions change. An integral component of proactive adaptive management planning requires forecasts of how changes in climate will affect individual species. This need has been identified my multiple federal agencies, including the U.S. Fish and Wildlife Service, National Park Service, Bureau of Land Management, and U.S. Forest Service. The goal of this project was to assist land and wildlife managers in anticipating which species are most vulnerable to changes in climate in the Southwest, and how resources can best be invested to facilitate adaptation. Researchers evaluated the current and future breeding ranges...

In the Southwestern U.S., rising temperatures and changing precipitation patterns are resulting in changes such as more frequent and severe wildfires and prolonged drought. Natural resource managers striving to make decisions in the face of these changing conditions can benefit from information on past, present, and future climate. While an array of climate assessments are available, it is unclear how useful or relevant this information is for resource management decision-making in the Southwest. This project sought to identify the types of environmental information that resource managers in the Southwest need to make climate-related management decisions. To meet this goal, researchers first assessed the degree...

Natural climate variability can obscure or enhance long-term trends in experienced weather due to climate change. This can happen temporarily on timescales of a season to several years to a decade or two. Natural variability is poorly described and attributed to specific causes, contributing to uncertainty and misunderstandings about the nature of climate change that stakeholders and resource managers attempt to anticipate. There exists, therefore, a need to clarify the magnitude and causality of natural climate variability. This connection needs to be explained for locally-experienced weather and particularly for daily extreme events, whose seasonal behavior impacts both resources and imagination. Conversely, it...

Understanding current and future threat of invasive annual grasses (invasives) in the sagebrush ecosystem is a critical need for resource and wildfire management, biological planning and conservation design for this imperiled ecosystem. Many land managers are challenged with selecting the most appropriate invasives dataset or tool for their planning efforts due to difficulties in understanding dataset attributes (e.g., scale, resolution, sensitivity) and lining them up with management objectives. This project will: (1) develop an annotated bibliography of recent, peer-reviewed literature for three invasive annual grass species of highest concern (cheatgrass, medusahead, and ventenata); (2) review all geospatial...
