AUGUST STREAM DISCHARGE TRENDS PORTEND IMPACTS OF CLIMATE CHANGE IN THE NORTHERN ROCKIES
… in late summer discharge patterns across the Northern Rockies (NR). Water in the interior western United States is a vital resource and the demand for this resource has increased. Watersheds in the NR are mainly snowmelt dominated in that they depend on the seasonal flux of snow-melt during …

Ranches with Wolves: How straight talk is the salvation of open range in the Northern Rockies
Since U.S. Fish and Wildlife Service reintroduced gray wolves into Yellowstone National Park and central Idaho in 1995 and 1996, conflicts between wolves and livestock have increased as the wolf population has grown and expanded. Ranchers in wolf country face a changing ecology that now includes …

Development and Application of a MODIS Snowmelt Model for Northwestern Montana
… timing of the spring melt pulse in a large-scale northern Rockies watershed. We employ a snowmelt model to investigate historical records of the initiation of spring snowmelt runoff. Two watersheds were selected as test sites: (1) St. Mary – a small (81 km2) basin east of the continental divide …

Analysis of Extreme Reversals in Seasonal and Annual Precipitation Anomalies Across the United States, 1895-2014
… several regions, including the northwest, the Northern Rockies and Plains, and the Ohio Valley. Relationships between the winter-to-winter PR time series and an index representing the El Nino-Southern Oscillation (ENSO) phenomenon were examined. The winter-to-winter PR time series of the …

Carbon Storage in Old-Growth Western Larch (Larix occidentalis) Forests of Western Montana
… the unique qualities of old-growth of the Northern Rockies. In this thesis, I first present a review of existing literature on definitions and characteristics of old-growth ecosystems of the Pacific Northwest and contrast these with old-growth forests of the Northern Rockies. In the second …

Vegetation Variability and Its Hydro-Climatologic Dependence
… the Blue Ridge, Central Basin and Range, and Northern Rockies Ecoregions (CEC/EPA Level III Ecoregions), which exhibit large inter-annual vegetation variability, are chosen as the focus of the second phase of the current research. These ecoregions represent areas with complex terrain, minimal …

CHANGES IN FIRE SEASON PRECIPITATION IN IDAHO AND MONTANA FROM 1982-2006
… could result in more active fire seasons in the Northern Rockies and may explain some of the changes in fire season that have been previously attributed to earlier Spring snowmelt and warmer temperatures.

ASSESSING FOREST RESPONSES TO CLIMATE CHANGE AND RESOLVING PRODUCTIVITY MEASUREMENTS ACROSS SPATIAL SCALES
… climate change scenarios on forests of the US Northern Rockies. Results show an increase in growing season length and in water stress, and a decrease in snow quantities and in number of days with ground snow for all forests by 2089. Under the driest and warmest scenario, the majority of the …
