Lichen communities have been shown to be sensitive to changes in environmental pollution and climate change, making them good candidates for long-term monitoring of ecosystem conditions. Building upon prior efforts, a partnership among the National Park Service (NPS), the US Forest Service, and Oregon State University (OSU) has been formed to integrate existing lichen data across southwest, south-central, and southeast Alaska, and collaboratively develop and refine tools for monitoring climate change and air quality change. This project continues that partnership between NPS and OSU to conduct analyses and modeling of lichen communities for environmental monitoring purposes. Project objectives include developing...
The National Park Service and the University of Washington will collaborate in a project to estimate the current and near-future outburst flood potential from the Nisqually Glacier and associated downstream hazards along the Nisqually River and the Longmire work area. Recent survey data indicates that lower glacier ice velocities are slowing down to an alarming level. Stagnant ice is strongly associated with destructive summer j?kulhaups (glacier outburst floods). J?kulhaups usually turn into highly erosive and damaging debris flows, as they course down glacier-sourced rivers. They can produce flood peaks greatly in excess of floods from precipitation events. The only time Longmire, a major visitor and work center...
This is a collaborative project between UW and NPS to explore issues for cultural resource management based on spatially and temporally extensive problems such as climate change adaptation. In this project, an information needs assessment for climate change decision making will be conducted, and a process for using that information will be proposed that informs vulnerabilities and risk, and outlines an information system that enables flow between producers and users from multiple disciplines. The goal is to support cultural resource managers who must decide where to focus attention and resources to most effectively preserve our cultural heritage. The project will consist of information needs assessments, review...
Bumble bee pollinators provide invaluable ecosystem services to wild flowering plants. However, recent studies throughout the U.S. have documented range wide decline in bumble bee abundance and diversity. Bumble bee decline has been attributed to climate warming, pathogen outbreaks, and land-use change. In the wake of climate change, bumble bees are at high extinction risk considering their mostly alpine and temperate distribution. Recent surveys have documented changes in bumble bee abundance within some North Coast and Cascade Network (NCCN) Parks, including the disappearance of Bombus occidentalis from most of the Pacific Northwest. This is a collaborative study to provide information on the status of important...
Predicted climate impacts on arid U.S. Great Basin wetlands will alter their number, distribution, and quality (e.g., salinity). The scarcity and isolation of these wetlands make them essential not only to wildlife but to ranchers, farmers, and urban areas that rely on their ecosystem services. Great Basin wetlands are important habitats for migratory birds at high volumes, but they become concentrated mineral brines at low volumes, narrowing waterbird food resources as salinity rises. Thus, many resource managers need to answer two questions: How will climate change affect migratory bird species dependent on climate-sensitive wetlands? How should management strategies balance human-consumer uses of these water...
