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...

Tribal communities’ traditions, identities, and economies rely heavily on local natural resources, making tribes especially vulnerable to climate change impacts, including changes in seasonal patterns and the potential loss of culturally and economically important species. The goal of this project was to build tribal capacity in the Pacific Northwest to successfully plan for and adapt to the effects of climate change. The funds associated with this project supported the Affiliated Tribes of Northwest Indians (ATNI) Tribal Leaders Summit on Climate Change held on March 10-11, 2015 in Portland, Oregon. The summit gathered tribal leaders to discuss climate change impacts; share tribal strategies, plans, and policies;...

In order for science to have the most impact on resource management, it needs to directly address the questions that managers and other stakeholders have. Essentially, the ways in which researchers and resource managers collaborate can affect the use of scientific information in decision-making. Previous research has shown that relatively more collaboration between researchers and resource managers (or even the general public) tends to lead to more and more effective use of new scientific information. However, we do not yet have good ways to evaluate these research processes or the outcomes we expect them to produce. This project will assess the key variables necessary for the successful production of usable climate...

This project identifies opportunities to manage flows, connections, and landscapes to increase the resilience of human communities and ecosystems. This research identifies dynamic and adaptive solutions to managing river flows that allow continued provision of valuable infrastructure services such as flood control, hydropower, and water supply, while also supporting thriving river ecosystems - both today and into the future. The goals of the research were to: 1) Evaluate the potential impacts of climate change on hydrologic regimes, 2) Determine the flow regime changes that will be required to provide riverine environmental services and any risk associated with these changes, and 3) Explore management alternatives...

We propose to empirically characterize hydrology/fish-production relationships for different ecological groups of fishes living in the Red River and associated reservoir habitats by: 1. Correlating historic hydrologic data with catch curve residuals, and 2. Annual growth rate estimates of fish collected from the Red River and associated reservoirs. The catch curve residual approach for indexing year class strength has been validated and successfully used to quantify the relationship between reservoir hydrology and YOY recruitment for white crappie and largemouth. The essence of the approach is as follows. Catch curves (a correlation between the natural log of fish abundance and age) are used to measure total instantaneous...

Ecosystem services provided by floodplains include removal of nitrogen, phosphorus, and sediments, and sequestration of carbon. Effectiveness of floodplains in providing these services is dependent on the extent and location of connection between floodplain and river. Tributary loading of sediments, nitrogen and phosphorus to the Upper Mississippi River contribute to the development of river and coastal eutrophication as well as hypoxic conditions in the Gulf of Mexico. Recent research has shown that management of river connectivity of channels to floodplains is an effective mitigation strategy to remove nutrients, sediment, and carbon from river flows. The confluence of the Maquoketa and Mississippi Rivers is a...
Refinement of Gopher Tortoise Habitat Identification and Related Land Cover Data. The benefits of this project include: 1) much improved gopher tortoise remote habitat identification that could have a strong influence on potential listing status (with the likelihood that significantly more habitat may be identified); 2) better statewide land cover data regarding scrubby flatwoods and potentially refined mesic flatwoods and dry prairie classifications; and 3) potential spin off benefits regarding better habitat identification for related species such as gopher frogs and other xeric adapted species that might be found in on drier flatwoods and dry prairie sites.Continuation of Water Restoration Analyses. Considerable...

Mapping of barriers and statistical prediction of their passability is now fairly complete in the Great Lakes basin, yet field assessments of barrier characteristics and passability to migratory fishes are spotty. We will use the Lake Michigan basin as a pilot area for comprehensive field assessment of dam condition, dimensions, and passage technologies. These characteristics will be incorporated into our barrier database, enabling improved estimates of removal costs, watershed cumulative passability, and infrastructure maintenance challenges. In parallel, we will conduct field assessments of passability to spring migrations of Great Lakes fishes in 15 Wisconsin watersheds. Recording the upstream limits of migrations...

The primary objective of this project is to develop a short synthesis report assessing 11 habitats, using a variety of ecological indicators. The report will be one tool that the South Atlantic LCC can use to inform decision-makers, stakeholders, and the general public about the health of South Atlantic habitats. To achieve this project, six discrete project tasks have been identified and are outlined in the next section.1) Project start-up and pre-workshop preparation: IAN will carefully review the Conservation Blueprint habitats and the indicators used to assess the health of these habitats. We will become familiar with the thresholds and data analysis that the South Atlantic LCC is using for their project. This...

Maple syrup is produced from the sap of sugar maple trees collected in the late winter and early spring. Native American tribes have collected and boiled down sap for centuries, and the tapping of maple trees is a cultural touchstone for many people in the Northeast and Midwest. Overall demand for maple syrup has been rapidly rising as more people appreciate this natural sweetener. Yet because the tapping season is dependent on weather conditions, there is concern about the sustainability of maple sugaring as the region’s climate changes. The distribution of sugar maple could move north into Canada and the sap flow season may become shorter in the future. Not only could these changes affect producers and consumers...

In the western U.S., rising temperatures and pronounced drought conditions pose significant challenges to public land managers. Widespread declines of multiple plant species have already been observed, providing insight into what the future could look like for vegetation in the region as conditions are projected to become warmer and drier. To understand how vulnerable western ecosystems are to drought, managers need to know which climatic and soil conditions cause habitats to change, and at what rate these changes may occur – important topics on which there is little available data. This project seeks to identify the vulnerability of habitats in the western U.S. to drought. Researchers will compare changes in...
