Surface Disturbance and Reclamation Tracking Tool (SDARTT)

The Bureau of Land Management (BLM) and the United States Geological Survey (USGS) have partnered to create the Surface Disturbance Analysis and Reclamation Tracking Tool (SDARTT). SDARTT is to be the national repository for and analysis tool of disturbance data pertaining to public land operations for the BLM. Users will upload disturbance and reclamation data to SDARTT to map, analyze, and...

Yellowstone Lake Acoustic Biotelemetry Project Home Page

Fishery biologists and managers are increasingly consumed with the recovery and restoration of native trout and salmon throughout the western United States. These fish historically inhabited a variety of freshwater habitats, but have declined due to habitat degradation, fragmentation and introduction of nonnative species. Introduced fishes constitute a major threat to the persistence of native...

Developing stream temperature networks for the Greater Yellowstone to aid in managing aquatic resources under a changing climate

The topographic diversity and extensive area of protected public land within the Greater Yellowstone demonstrate the importance of this region as a natural resource reserve. Understanding the effects of anticipated changes in climate on aquatic resources and means for managing these resources will ultimately require accurate linkages between empirical data and regional climatic patterns. This...

Evaluating the linkages between regional climate patterns, local climate data, and native Yellowstone cutthroat trout (Oncorhynchus clarkii bouvieri) and non-native brook trout (Salvelinus fontinalis) growth, survival, and life-history expressions.

Beyond large-scale climate models, it is becoming increasingly important to quantify how regional climate patterns link with in situ stream temperatures and hydrologic regimes and concomitantly, fish behavior, growth, and survival. Here, we are using comprehensive mark-recapture techniques to evaluate how changing climatic conditions are likely to influence native westslope cutthroat trout and...

Ecology of Elk on Department of Interior Lands in Southwest Wyoming

Between 2005 and 2010, we radio- collared 61 female elk (Cervus elaphus) on Fossil Butte National Monument and 12 female elk near Cokeville, Wyoming, slightly northwest of the Monument, all from the West Green River herd. We are using the 209,250 locations from these elk to identify seasonal distribution patterns, evaluate habitat use, and assess factors influencing the timing of migration.  ...

Developing a mechanistic understanding between recent climate patterns and Aquatic Vital Signs in the Greater Yellowstone Network

The National Park Service Inventory and Monitoring program was established to provide park managers with a broad understanding of the status of park resources using the best available science. This program acknowledges that NPS managers are confronted with complex challenges associated with the management of dynamic landscapes responding to multiple, interacting drivers of change. To provide...

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...

Volcano Hazards Assessments Help Mitigate Disasters

The Volcano Hazards Program develops long-range volcano hazards assessments. These includes a summary of the specific hazards, their impact areas, and a map showing ground-hazard zones. The assessments are also critical for planning long-term land-use and effective emergency-response measures, especially when a volcano begins to show signs of unrest.

Current Alerts for U.S. Volcanoes

Volcano-alert notifications are produced by Volcano Observatory scientists based on analysis of data from monitoring networks, direct observations, and satellite sensors. They are issued for both increasing and decreasing volcanic activity and include text about the nature of the unrest or eruption and about potential or current hazards and likely outcomes.

Previous mineral-resource assessment data compilation for the U.S. Geological Survey Sagebrush Mineral-Resource Assessment Project

This data release consists of a compilation of previously published mineral potential maps that were used for the Sagebrush Mineral-Resource Assessment (SaMiRA) project. This information was used as guides for assessing mineral potential assessment of approximately 10 million acres in Idaho, Montana, Nevada, Utah, and Wyoming. Specifically, the compilation was used to identify the d
