Unified Interior Regions


The Rocky Mountain Region ranges from the Colorado Rockies to the Western Deserts to the Great Plains. The Rocky Mountain Region conducts multi- and interdisciplinary research and monitoring in locations across the Region, the United States, around the world, and across our solar system.

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...

Yellowstone Volcano Observatory (YVO)

Monitors and studies the active geologic processes and hazards of the Yellowstone Plateau volcanic field and its caldera. Yellowstone National Park contains the largest and most diverse collection of natural thermal features in the world. YVO also monitors volcanic activity in Montana, Wyoming, Colorado, Utah, and New Mexico.

Amphibian Research and Monitoring Initiative: Rocky Mountain Region

Decline of amphibian populations worldwide has prompted an international effort to determine causes of decline in various locations and ecosytems. Some causes which have been suggested include habitat alteration, introduced species, disease, and environmental stressors such as ultraviolet radiation, agricultural chemicals in groundwater, and contaminants in atmospheric deposition. The ...

Lamar River Downstream View

This photo was taken within Yellowstone National Park and shows a cableway view of Lamar River near Tower Ranger Station. Less than half a mile downstream, the Lamar River flows into the more well-known Yellowstone River. When this photo was taken, flows were just a bit above average at the streamgage.

Dropping the Wire Weight

The wire weight was dropped from this bridge to measure the stream stage of the Blacks Fork River near Lyman, Wyoming. Even with an early start, it is a struggle to get work done before an afternoon storm rolls in.

LARAMIE, Wy. — Previous research has claimed that the reintroduction of wolves to Yellowstone National Park in 1995 is helping restore quaking aspen in risky areas where wolves prowl. But apparently elk hungry for winter food had a different idea.

Continued high flows in the upper North Platte River and its tributaries have resulted in the river reaching an all-time record at the USGS streamgage on the North Platte River above Seminoe Reservoir near Sinclair. The gage height of 11.6 feet reached on June 14, 2010 is 2.6 feet above the National Weather Service flood stage.
