An investigation of aquatic invasive species in pristine sites in the Greater Yellowstone Area

Aquatic invasive species (AIS) are aquatic organisms that move into ecosystems beyond their natural, historic range and cause severe and irreversible damage to the habitats they invade. Most AIS arrive as a direct result of human activity, such as boating and angling. The threat of AIS introduction is especially high in the Greater Yellowstone Area, as humans from all over the world come to...

RARMI: Northern Rocky Mountain Science Center (NOROCK) Apex Sites

In contrast to RARMI study areas in Colorado that have 10 or more years of records of continuous population monitoring, there are fewer long-term datasets for amphibian populations in the northern Rocky Mountains. The exception is an ongoing study of Columbia spotted frogs at Lodge Creek, Yellowstone National Park. Three other long-term research and monitoring areas have been established in...

RARMI: Fort Collins Science Center (FORT) Apex Sites

FORT is monitoring populations of amphibians at three apex sites using capture-recapture methods. Our goal in monitoring populations is to detect fluctuations in population size, sex ratio, survival, and recruitment. Through long-term monitoring, we can also address breeding phenology in relation to elevation, weather, and climate. Other specific questions can be asked about issues such as...

COMPLETED: Using thermal imagery to assess wolf hairloss from sarcoptic mange

Researchers at NOROCK and their partners used thermal cameras at the Grizzly and Wolf Discovery Center in Montana to assess the amount of heat lost under a range of environmental conditions with and without hair. These methods help scientists better understand how mange operates in wild wolves throughout the Greater...

Impacts of climate change on habitat quality: plant phenology interactions with animal use and fitness

Weather and climate impact terrestrial wildlife habitat through their influences on plant productivity. Plant phenology – the timing of life-history events such as green-up, flowering and senescence – provides one indicator of the timing and magnitude of productivity. Changes and variability in plant phenology in space and time are indicators of habitat quality, which is a driver of fitness...

Identification of Fire Refugia in Rocky Mountain Ecosystems of the U.S. and Canada: Development and Application of the Refugium Concept for Biodiversity Conservation over Large Spatial and Temporal Scales

We described the climate space of fire regimes in northwestern North America (Whitman and others 2015), and we are refining an approach to identify fire refugia – areas that do not burn or burn with lower severity through multiple fire events. We continue our collaboration to test the function of refugia for biodiversity conservation under current and future climate and fire scenarios. We...

Monitoring for Potential Effects of the Gold King Mine Release on Water Quality in the Animas and San Juan Rivers in New Mexico using Continuous Monitors and Automatic Samplers

On August 5, 2015, about three million gallons of water and sediment were released from the Gold King Mine near Silverton, Colorado, into Cement Creek, a tributary of the Animas River. The New Mexico Environment Department, among other State, Tribal, and local entities in CO, NM, and UT, is concerned that metals associated with the water and sediment released from the Gold King Mine could have...

Characterization of Water Quality and Biology in the Fountain Creek Watershed

Monument and Fountain Creeks and their respective watersheds, located in the Front Range of Colorado, serve as important drainages for surface runoff, waste-water treatment operations, and as a water supply for downstream agricultural needs. As population growth continues in these watersheds, more and more pressures are being applied to the receiving streams, especially Fountain Creek. ...

Lower Gunnison River Basin Groundwater Selenium

The east side of the Uncompahgre River Basin has been a known contributor of dissolved selenium to recipient streams. Discharge of groundwater containing dissolved selenium contributes to surface-water selenium concentrations and loads; however, the groundwater system on the east side of the Uncompahgre River Basin is not well characterized. The U.S. Geological Survey, in cooperation with the...

StreamStats for Colorado

StreamStats is a map based Web application that provides information that can be used by engineers, managers, and planners to make informed decisions on water-related activities.  The map-based user interface can be used to delineate drainage areas, get basin characteristics and estimates of flow statistics.  StreamStats allows for the analysis of upstream and downstream relations along...

Southern Rockies Landscape Conservation Cooperative Streamgage Database and Network Analysis

Within the Southern Rockies Landscape Conservation Cooperative (SRLCC), streamflow information is needed for a wide variety of hydrologic conditions to understand streamflow in the context of ecological services, water availability and use, or water quality.

 

USGS Science Centers in Region 7-Upper Colorado Basin collect a wide variety of natural resource data types including spatial, geologic, hydrologic, and biologic data. Data included in USGS-series publications that are not publically available in USGS databases are published in Data Releases. Tools are USGS products that can be used to analyze those types of data.

Water, Energy, and Biogeochemical Budgets (WEBB): Loch Vale Data

The chemistry of streams and lakes have been monitored in Loch Vale since 1983. Changes in stream and lake chemistry have been traced to variations in climate and atmospheric deposition of pollutants. Samples are collected throughout the year in Loch Vale. This provides information on seasonal variations in stream and lake chemistry.
