Natural resource managers face an unprecedented challenge ? how to plan and manage for local and regional effects of climate change. In the Pacific Northwest, temperatures and precipitation changes are affecting snowpack levels, hydrology, and disturbance regimes such as fire. These changes will affect species? distributions and phenologies, creating cascading effects on ecological systems that will greatly alter many of the resources of our national parks. To address these impacts, managers need detailed information on which species and systems are most susceptible to climate change and how projected changes in climate are likely to affect them. This project will answer critical research questions of which species...
Current and projected climatic change is threatening montane and subalpine species in National Parks throughout the western U.S., including those within the Klamath, Upper Columbia Basin, and Sierra Nevada Networks. Scenario planning is needed to help protected-area decision-makers identify and prepare for potentially substantial changes to high-elevation ecosystems. The National Park Service and the Oregon Institute of Technology will collaborate to conduct climate change scenario planning for montane and subalpine species, focusing on whitebark pine (Pinus albicaula) and pika (Ochotona princeps). Phase 1 of this project will develop a framework for scenario planning across these networks by initiating the Orientation...
The National Park Service and the University of Washington will collaborate in a project to summarize Nisqually glacier changes over the past century and offer predictions for future changes, under various climate change scenarios. The Nisqually glacier is among the most accessible in the United States, and surveys have been regularly made (since 1931) to determine changes in the elevation of the surface, along 3 lateral transects. These long-running data will be examined and analyzed from the perspective of other glacier monitoring projects, and on-going climate change. The results will be interpreted in several contexts including: (1) glacier dynamics; (2) climate change; (3) glacier mass balance; and, most importantly,...
This is a collaborative project between the National Park Service (NPS) and the University of Washington to use new satellite data to assess changes in several glaciers in North Cascades National Park (NOCA). Recent investigations have shown that the glaciers in the Washington Cascades are retreating rapidly in a warming climate. NPS has monitoring data from four glaciers at NOCA. These data will be analyzed with new WorldView stereo satellite data to produce digital elevation models (DEMs) with high accuracy for four NOCA glaciers, and to calculate volume changes in these glaciers. Expected products include four DEMs with auxiliary products (e.g., image data) and a final report that describes the methods and detected...
This is a collaborative project between the National Park Service (NPS) and Oregon State University (OSU) for the purpose of studying the genetic connectivity of pika populations in five NPS units. OSU researchers will use individual and population-based genetic analyses to systematically estimate genetic distances among individuals and gene flow among patches or populations in NPS units in two very different habitats (talus vs. lava beds). Genetic distances among individuals or gene flow among groups reflect (in part) the degree that individuals are related and that populations are interacting via dispersal. Thus, researchers will use variation in genetic distance or gene flow to infer how landscapes (e.g., dispersal...
The National Park Service and Portland State University will collaborate in a field-based project to accurately map the spatial extent and status of the rapidly changing glacial ice on Mount Rainier. In particular, areas of active (moving) ice will be distinguished from stagnant (non-moving) ice, which is of premier importance for hazard planning. In the future, glacier maps can be updated rapidly using remotely sensed data, and avoiding expensive future field efforts. Deliverables will include identifying the true spatial extents of the glaciers, including: rock and debris covered areas (usually not mapped correctly in earlier surveys), and stagnant (versus active, moving) ice. Additionally, the bedrock topography...
