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.

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.

Jaime and Nicole survey the trench control points with RTK GPS. At this point the GPS survey is redundant, but later we (mostly Jaime) will compare the GPS, total station, and scale bar data (not shown) to evaluate accuracy and ease of use for future trenches.

Greater sage-grouse populations have declined substantially in many areas in the West, though populations in some locations remain relatively stable, according to a comprehensive publication written by federal, state, and non-governmental organizations. The population assessment is one of numerous sage-grouse topics covered in the 24 chapters released today.
