Modeling streamflow is an important approach for understanding landscape-scale drivers of flow and estimating flows where there are no streamgage records. In this study conducted by the U.S. Geological Survey in cooperation with Colorado State University, the objectives were to model streamflow metrics on small, ungaged streams in the Upper Colorado River Basin and identify streams that are potentially threatened with becoming intermittent under drier climate conditions. The Upper Colorado River Basin is a region that is critical for water resources and also projected to experience large future climate shifts toward a drying climate. A random forest modeling approach was used to model the relationship between streamflow...
Five hydrologic and landscape databases were developed by the U.S. Geological Survey, in cooperation with the U.S. Fish and Wildlife Service, for select National Wildlife Refuges (NWRs) in southeastern United States: (1) the Cahaba River NWR and contributing watersheds in Alabama, (2) the Caloosahatchee and J.N. "Ding" Darling NWRs and contributing watersheds in Florida, (3) the Clarks River NWR and contributing watersheds in Kentucky, Tennessee, and Mississippi, (4) the Lower Suwannee NWR and contributing watersheds in Georgia and Florida, and (5) the Okefenokee NWR and contributing watersheds in Georgia and Florida. The databases were developed as an assessment and evaluation tool to use in examining refuge-specific...

The U.S. Geological Survey (USGS) maintains over 8,000 streamgages across the U.S. Streamgages in Illinois are operated by the USGS Illinois-Iowa Water Science Center (USGS IL-IA WSC). Gage-height data at many USGS streamgages were collected on paper-punch tapes during the period of 1965 to 1985 in Illinois. These data were not saved in the National Water Information System (NWIS) due to lack of sufficient computer storage at that time. The USGS IL-IA WSC currently has the equivalent of 2,049 years of data from 152 streamgages on paper tapes stored at the National Archive and Records Administration (NARA) Federal Records Center that are not in NWIS. All of these data need to be stored in NWIS for public use before...

This assessment was conducted to fulfill the requirements of section 712 of the Energy Independence and Security Act of 2007 and to contribute to knowledge of the storage, fluxes, and balance of carbon and methane gas in ecosystems of Alaska. The carbon and methane variables were examined for major terrestrial ecosystems (uplands and wetlands) and inland aquatic ecosystems in Alaska in two time periods: baseline (from 1950 through 2009) and future (projections from 2010 through 2099). The assessment used measured and observed data and remote sensing, statistical methods, and simulation models. The national assessment, conducted using the methodology described in SIR 2010-5233, has been completed for the conterminous...

Future climate change may significantly alter the distributions of many plant taxa. The effects of climate change may be particularly large in mountainous regions where climate can vary significantly with elevation. Understanding potential future vegetation changes in these regions requires methods that can resolve vegetation responses to climate change at fine spatial resolutions. This research was projected using three models: cgcm31, hadley, and current. We used LPJ, a dynamic global vegetation model, to assess potential future vegetation changes for a large topographically complex area of the northwest United States and southwest Canada (38.0–58.0°N latitude by 136.6–103.0°W longitude). LPJ is a process-based...

The Lakewide Management Plans (LaMPs) within the Great Lakes region are examples of broad-scale, collaborative resource-management efforts that require a sound ecosystems approach. Yet, the LaMP process is lacking a holistic framework that allows these individual actions to be planned and understood within the broader context of the Great Lakes ecosystem. To help this issue, a conceptual framework for Lake Michigan Coastal/Nearshore Ecosystems was developed to address for major LaMP goals; Can we drink the water?, Can we eat the fish?, Can we swim in the water?, Are all habitats healthy, naturally diverse, and sufficient to sustain viable biological communities?

Managers need information on the grazing ecology of bison and elk in the Great Sand Dunes National Park and Preserve to develop science-based management alternatives. This study will determine elk and bison population status and movements, effects of herbivory, and suitable habitat and population potential in the park. From these data scientists will develop an elk/bison grazing model that includes grazing as a significant natural ecological process and protects sensitive native plant communities. The study will also provide information for developing a predictive model to be used in a planning process for management agencies, and includes monitoring the effects of treatments and new experiments on the distribution...

The SRLCC provided funds to the states in Arizona and New Mexico to support development of the states’ Crucial Habitat Assessment Tools (CHATs) which provide a decision support system to better incorporate wildlife values, sensitive animals and plants, and important ecosystem features into land use decision-making to reduce conflicts and surprises. Several states have released wildlife mapping tools that are the foundation for displaying crucial wildlife and corridor information. The state and regional CHATs are non-regulatory, and give project planners and the general public access to credible scientific data on a broad scale for use in project analysis, siting and planning. This includes large-scale development...

In this proposal we investigate how tree selection at the local scale affects biodiversity and ecosystem services (Obj. 1). We then look regionally to determine the extent to which trees in cities can be used to predict heat-related threats to rural forests (Obj. 2). We will leverage ongoing investigations of heat-related stress and pest outbreaks in urban and rural forests to develop management recommendations for both systems. These ongoing projects provide a knowledge-base, infrastructure (e.g. study sites), equipment (e.g. Li-Cor Photosynthesis System), and outreach opportunities that will extend the impact of this project (see Synergistic and Future Funding section below). We will also convene a working group...

Ouray National Wildlife Refuge (NWR) is located in the northeast corner of Utah along the Green River and is part of the Upper Colorado River System and the Colorado Plateau. The Colorado Plateau is home to 19 species of bats, some of which are quite rare. Of those 19 species, a few occur only in more southern parts of the plateau and would not be expected to be found at Ouray NWR. Based on previous syntheses of bat distributions in Utah, there could potentially be 17 species at Ouray NWR (Armstrong 1977; Durrant 1952). No detailed information on which species of bats occur at Ouray NWR or their relative abundance exists, however. It has been assumed that Ouray NWR would provide excellent habitat for bats, as the...

We used NLCD 2011, SSURGO, and SEGAP data to map the density of desired resources for open pine ecosystems and six focal species of birds and 2 reptiles within the historic range of longleaf pine east of the Mississippi River. Binary rasters were created of sites with desired characteristics such as land form, hydrology, land use and land cover, soils, potential habitat for focal species, and putative source populations of focal species. Each raster was smoothed using a kernel density estimator. Rasters were combined and scaled to map priority locations for the management of each focal species. Species’ rasters were combined and scaled to provide maps of overall priority for birds and for birds and reptiles. For...

The Mediterranean ecosystems of southern California are some of the most ecologically diverse systems in the world. The diversity of plants and animals, as well as high rates of endemism, make the area a biodiversity hotspot. High diversity in plant and animal species contributes greatly to the health and productivity of ecosystems, and plays an important role in the local and state economy (e.g. tourism, food crops, etc.). San Diego County's complex topography, highly variable precipitation and climate play a large role in determining the biology of the region. Changing temperatures and precipitation patterns due to climate change would alter the region's climate and add to other stressors such as habitat fragmentation...
