This data release contains monthly 270-meter resolution Basin Characterization Model (BCMv8) climate and hydrologic variables for Localized Constructed Analog (LOCA; Pierce et al., 2014)-downscaled ACCESS 1.0 Global Climate Model (GCM) for Representative Concentration Pathway (RCP) 4.5 (medium-low emissions) and 8.5 (high emissions) for hydrologic California. The LOCA climate scenarios span water years 1950 to 2099 with greenhouse-gas forcings beginning in 2006. The LOCA downscaling method has been shown to produce better estimates of extreme events and reduces the common downscaling problem of too many low-precipitation days (Pierce et al., 2014). Ten GCMs were selected from the full ensemble of models from the...
This data release contains monthly 270-meter resolution Basin Characterization Model (BCMv8) climate and hydrologic variables for Localized Constructed Analog (LOCA; Pierce et al., 2014)-downscaled Global Climate Models (GCMs) for Representative Concentration Pathway (RCP) 4.5 (medium-low emissions) and 8.5 (high emissions) for hydrologic California. The 20 future climate scenarios consist of ten GCMs with RCP 4.5 and 8.5 each: ACCESS 1.0, CanESM2, CCSM4, CESM1-BGC, CMCC-CMS, CNRM-CM5, GFDL-CM3, HadGEM2-CC, HadGEM2-ES, and MIROC5. The LOCA climate scenarios span water years 1950 to 2099 with greenhouse-gas forcings beginning in 2006. The LOCA downscaling method has been shown to produce better estimates of extreme...
Background Climate change during the past century has resulted in changes to precipitation amounts, form (rain vs. snow), as well as frequency and intensity in the northeastern US (Huntington et al., 2009). Additional changes in precipitation are forecast for the 21st Century as the global and regional climate is expected to warm substantially (Hayhoe et al., 2007). These ongoing and projected future changes in precipitation along with other related changes to evapotranspiration rates and land use patterns will result in changes in streamflow patterns as well (Hayhoe et al., 2007). Although precipitation amounts have generally increased in the Northeast during the past 20-30 years (Huntington et al., 2009),...

Background Streams and rivers are an important environmental resource and provide water for many human needs. Streamflow is a measure of the volume of water carried by rivers and streams. Changes in streamflow can directly influence the supply of water available for human consumption, irrigation, generating electricity, and other needs. In addition, many plants and animals depend on streamflow for habitat and survival. Streamflow naturally varies over the course of a year. For example, rivers and streams in many parts of the country have their highest (peak) flow when snow melts in the spring. The amount of streamflow is important because high flows can cause erosion and damaging floods, while very low flows...

A Handbook for Resource Managers to Understand and Utilize Sea-Level Rise and Coastal Wetland Models
Coastal wetlands and the many beneficial services they provide (e.g., purifying water, buffering storm surge, providing habitat) are changing and disappearing as a result of sea-level rise brought about by climate change. Scientists have developed a wealth of information and resources to predict and aid decision-making related to sea-level rise. However, while some of these resources are easily accessible by coastal managers, many others require more expert knowledge to understand or utilize. The goal of this project was to collate science and models pertaining to the effects of sea-level on coastal wetlands into a format that would be accessible and useful to resource managers. Researchers conducted training sessions...

The Southeastern U.S. spans broad ranges of physiographic settings and contains a wide variety of aquatic systems that provide habitat for hundreds of endemic aquatic species that pose interesting challenges and opportunities for managers of aquatic resources, particularly in the face of climate change. For example, the Southeast contains the southernmost populations of the eastern brook trout and other cold-water dependent species. Climate change is predicted to increase temperatures in the South and is likely to have a substantial effect on extant populations of cold-water biota. Thus, aquatic managers are tasked with developing strategies for preserving cold-water dependent biota, such as eastern brook trout,...

The USGS National Climate Change and Wildlife Science Center (NCCWSC), as part of the work of the Interagency Land Management Adaptation Group (ILMAG), initiated a project in 2013 to develop plans for a searchable, public registry on climate change vulnerability assessments. Member agencies from the USGCRP Adaptation Science Work Group, the Association of Fish and Wildlife Agencies (AFWA), and several NGO’s also contributed. Vulnerability assessments are important for identifying resources that are most likely to be affected by climate change and providing insights on why certain resources are vulnerable. Consequently, they provide valuable information for informing climate change adaptation planning. CRAVe allows...

Problem The discharge of freshwater and associated loading of nutrients and other dissolved constituents from the Long Island aquifer system to surrounding estuaries and their tributaries are increasingly recognized as critical factors in the health of these ecosystems. However, further work is needed to scientifically characterize these factors and present them to the public in an appropriate manner. Many organizations have undertaken assessments of this discharge and loading for discrete groundwater source areas and (or) receiving surface waters, applying a variety of techniques and assumptions. In part, this is because there is no delineation of recharge areas to the island’s groundwater-fed streams and estuaries...
This data release contains monthly 270-meter resolution Basin Characterization Model (BCMv8) climate and hydrologic variables for Localized Constructed Analog (LOCA; Pierce et al., 2014)-downscaled GFDL-CM3 Global Climate Model (GCM) for Representative Concentration Pathway (RCP) 4.5 (medium-low emissions) and 8.5 (high emissions) for hydrologic California. The LOCA climate scenarios span water years 1950 to 2099 with greenhouse-gas forcings beginning in 2006.

FY2014Although the future of sage grouse depends on the future of sagebrush, we have limited ability to anticipate impacts of climate change on sagebrush populations. Current efforts to forecast sagebrush habitat typically rely on species distribution models (SDMs), which suffer from a variety of well-known weaknesses. However, by integrating SDMs with complementary research approaches, such as historical data analysis and mechanistic models, we can provide increased confidence in projections of habitat change. Our goal is to forecast the effect of climate change on the distribution and abundance of big sagebrush in order to inform conservation planning, and sage grouse management in particular, across the Intermountain...

A hydrologic model was developed as part of the Southeast Regional Assessment Project using the Precipitation Runoff Modeling System (PRMS), a deterministic, distributed-parameter, process-based system that simulates the effects of precipitation, temperature, and land use on basin hydrology. Streamflow and other components of the hydrologic cycle simulated by PRMS were used to inform other types of simulations such as water-temperature, hydrodynamic, and ecosystem-dynamics simulations.

The current information available for the Genesee River and watershed is insufficient to assess if the Beneficial Use Impairment (BUI) delisting criteria for the Rochester Embayment Area of Concern (AOC) can or have been met. With on-going and future projects that are implementing best practices to control soil erosion and the reduction of nutrients that reach the Rochester Embayment, the river and the watershed, it becomes a necessity to: 1.) collect more frequent Total Suspended Sediment (TSS) data for the Genesee River both within and outside of the AOC; and 2.) to have a study design capable of evaluating the impact/success of the current and proposed GLRI projects in the watershed. This project is envisioned...

Peak-flow frequency analysis is crucial in various water-resources management applications, including floodplain management and critical structure design. Federal guidelines for peak-flow frequency analyses, provided in Bulletin 17C, assume that the statistical properties of the hydrologic processes driving variability in peak flows do not change over time and so the frequency distribution of annual peak flows is stationary. Better understanding of long-term climatic persistence and further consideration of potential climate and land-use changes have caused the assumption of stationarity to be reexamined. This data release contains input data and results of a study investigating hydroclimatic trends in peak streamflow...
Quaking aspen populations are declining in much of the West due to altered fire regimes, competition with conifers, herbivory, drought, disease, and insect outbreaks. Aspen stands typically support higher bird biodiversity and abundance than surrounding habitat types, and maintaining current distribution and abundance of several bird species in the northern Great Basin is likely tied to the persistence of aspen in the landscape. This project examined the effects of climate change on aspen and associated bird communities by coupling empirical models of avian-habitat relationships with landscape simulations of vegetation community and disturbance dynamics under various climate change scenarios. Field data on avian...

Coral reefs are some of the most biologically rich and economically valuable ecosystems in the world. They provide food, fishing, and recreation opportunities for millions of people, protect coastlines from storms, and shelter thousands of plant and animal species. However, climate change is contributing to the degradation of coral reefs in two significant ways: warming temperature and increasing acidification of ocean waters. Scientists are actively working to gather more specific information about how these factors will impact coral reef ecosystems. The purpose of this study was to identify differences in climate vulnerability among three important reef-building coral species in the Florida Keys. Researchers...

FY2010In addition to regional Science and Traditional Ecological Knowledge projects that the Great Basin LCC (GBLCC) supports, GBLCC staff lend technical expertise to a range of projects and have contributed to important regional publications on a range of subjects. These publications range in type from textbooks, to management-oriented science and conservation plans, to scientific papers and have covered subjects like wind erosion following fire, soil microbiota response to drought, plant community resilience to invasive species, and alpine plant communities. In many cases these publications form foundations for scientifically-informed management strategies across the Great Basin.
