This project evaluates the connections between climate change impacts and health in Bristol Bay communities. Climate change impacts were assessed through the lens of public health, with an eye towards the potential effects on disease, injury, food and water security, and mental health. Three focal communities were included in this assessment: Nondalton, a lake community, Levelock, a river community, and Pilot Point, a coastal community. The resulting assessment reports will be used to assist focal communities, as well as neighboring communities, in addressing climate-change related issues.

The YKD is also home to the largest subsistence-based economy in Alaska. Yet, the low-lying landscape mosaic characterizing the YKD is at risk of massive change associated with projected sea level rise (SLR), increasing storm frequency and severity and permafrost degradation due to future climate change. Therefore, to conserve ecosystem services associated with the botanical and faunal richness in the YKD, management strategies in the region should not only be based on current ecosystem conditions, but also incorporate projected changes in landscape composition. The goal of this project is to provide managers and people living in the YKD, an assessment of the vulnerability of the landscape to future change and to...

Contemporary observations suggest that water may disappear entirely from portions of some North Slope stream-beds during periods of drought or low flow. Climate models project even drier summers in the future. This could pose a problem for migrating fish that must be able to move back and forth from breeding and summer feeding areas to scarce overwintering sites. This work uses the best available long-term hydrologic data set for the North Slope (in the upper Kuparuk River watershed) to develop a model to assess the vulnerability of stream systems to periodic drought, and the vulnerability of migrating fish to a loss of stream connectivity.

The Wildlife Conservation Society will assess the climate change vulnerability of bird species that regularly breed in substantial populations in Alaska using the NatureServe Climate Change Vulnerability Index (CCVI) tool. Initial work will focus on breeding birds in Arctic Alaska including shorebirds, waterfowl and waterbird species (loons, gulls, terns, jaegers), and land bird species (passerines, raptors, ptarmigan).

There are many challenges in detecting precipitation trends in Alaska. The most substantial are the small number of observations, inhomogeneities, differences among gridded data sets, and differentiating between long-term trends and decadal variability. Analyzing both station and regional products will increase our understanding of where local trends in precipitation may differ significantly from regional trends, providing key information for developing better downscaled climate projections. These in turn, will provide insight into fine scale heterogeneity in climate change that may be important in determining the stability of key habitat features, such as wetlands and insect avoidance areas. As a by-product of...

The Beaufort Sea coast in Arctic Alaska and neighboring northern Canada has recently experienced extreme and accelerated climate change, including a dramatic reduction in summer sea ice. Human systems will likely be impacted through changes to oil industry and community infrastructure currently in place along parts of the coast, to habitat availability for harvested species such as caribou, waterbirds, and anadromous fish, to culturally important landscape elements, and to both recreational and subsistence coastal access. We used literature review and structured interviews to 1) identify current, broad interests for ongoing coastal research in the arctic, 2) identify the best mechanisms and format for communicating...
This project designed a monitoring program and protocol to detect the effects of climate change on tidal marsh bird population abundance and distribution. It is a companion to “Tidal Marsh Bird Population and Habitat Assessment for San Francisco Bay under Future Climate Change Conditions” and will build on its products, enabling evaluation of the long-term viability of four tidal-marsh bird species threatened by impacts of climate change: Clapper Rail, Black Rail, Common Yellowthroat, and Song Sparrow (three endemic subspecies: San Pablo, Suisun, and Alameda). Information is available through the California Avian Data Center. See also: http://data.prbo.org/apps/sfbslr/index.php?page=lcc-page

This project evaluated the potential impacts of storm surges and relative sea level rise on nesting geese and eider species that commonly breed on the Yukon-Kuskokwim Delta (Y-K Delta). Habitat suitability maps for breeding waterbirds were developed to identify current waterbird breeding habitat and distributions. Short-term climate change impacts were assessed by comparing nest densities in relation to magnitude of storms that occurred in the prior fall from 2000-2013. Additionally, nest densities were modeled using random forests in relation to the time-integrated flood index (e.g., a storm specific measure accounting for both water depth and duration of flooding) for four modeled storms (2005, 2006, 2009, and...

Western Alaska is one of the fastest warming regions on the globe and recent trends are expected to continue into the next century, likely having substantial effects on the aquatic resources of this region. While increased air temperatures will have direct effects on water temperatures, indirect effects due to changes in precipitation, groundwater characteristics, and flow regimes may have much larger effects on aquatic ecosystems. Coastal watersheds of Western Alaska are expected to receive 25-50% more snow and 18-25% more rain in the next century. Future “climate warming” may actually cool some streams if the ratio of snow to rain increases for coastal watersheds, while rain-dominated streams are likely to become...
An urgent need exists to uniformly assess river corridors, including floodplains, and to prioritize areas for protection across the North Atlantic landscape. These are daunting tasks since there are no well-defined methods to delineate and assess scores of diverse river corridors in this region. The RiverSmart research group at UMass Amherst has made meaningful strides toward a uniform assessment of North Atlantic river corridors having assembled a task force of river specialists, analyzed ecologic and geomorphic threats, scrutinized the wide-ranging approaches to assess riparian habitats, and performed initial evaluations in diverse watersheds. In this project, we will build on this base. During the first year,...

The Shivwits Band of the Paiute Indian Tribe of Utah (PITU) has recognized the need to identify and assess the potential impacts of landscape-level stressors, such as climate change and drought, on tribal and ancestral lands and resources, such as water resources and culturally significant species and the habitats and ecosystems that support them. With funding from the Southern Rockies Landscape Conservation Cooperative, the Shivwits hired Barbara Dugelby1 of Round River Conservation Studies to conduct the assessment and prepare this report. The results of this report and the assessment will be integrated into the overall landscape level assessment of SRLCC priorities. This report presents a summary of the findings...

Arey Lagoon and Island, situated on the Beaufort Sea coast just west of Barter Island and within the Arctic National Wildlife Refuge (ANWR), was selected as a focus site for an in-depth study of coastal processes on a regional to local scale. Arey Lagoon and adjacent areas encompass a barrier island chain, a glacially fed river and delta (Hulahula and Ogpilak Rivers) from the Brooks Range watershed, low-lying tundra with coastal wet sedge, and thermokarst lakes that all may be vulnerable to the effects of changing storm patterns in response to climate change.Analysis of historical maps and imagery showed that Arey Lagoon mainland coast, partially protected by Arey Island from the direct attack of ocean waves, was...

Habitat loss and fragmentation are widely recognized as among the most important threats to global biodiversity. New analytical approaches are providing improved ability to predict the effects of landscape change on population connectivity at vast spatial extents. This paper presents an analysis of population connectivity for three species of conservation concern [swift fox (Vulpes velox); lesser prairie-chicken (Tympanuchus pallidicinctus); massasuaga (Sistrurus catenatus)] across the American Great Plains region. We used factorial least-cost path and resistant kernel analyses to predict effects of landscape conditions on corridor network connectivity. Our predictions of population connectivity provide testable...

To elucidate these potential “bottom up” effects of climate changes to Arctic ungulates and evaluate the trophic mismatch hypothesis, the Arctic Landscape Conservation Cooperative (ALCC), the Bureau of Land Management (BLM), the U.S. Geological Survey (USGS), Teck, Inc., and the National Park Service provided funding in 2012-14 to incorporate the calving and summer range of the Western Arctic caribou herd (WAH) into an ongoing inter-agency research and monitoring effort to examine the influences of climate change on the nutrient dynamics of caribou forages. This work is leveraging existing projects on the North Slope of Alaska that are primarily funded through the USGS Changing Arctic Ecosystems Initiative. Field...

Our overarching questions are: (1) How much of the river water and water-borne constituents (i.e. sediment, nutrients, organic matter) from the Jago, Okpilak and Hulahula rivers are coming from glacier melt? (2) How do inputs from these rivers affect the downstream ecosystems? (3) How will loss of glaciers affect these ecosystems? The study will help elucidate how inputs from glacier-dominated arctic rivers differ from unglaciated rivers, through a combination of ground work, boat work, and remote sensing. In Phase One of this study, we intend to explore the relationship between glaciers and coastal ecosystems. Our goal in this phase-one study is not to answer these questions conclusively but rather improve our...

Genetic, demographic, and environmental processes affect natural populations synergistically, and understanding their interplay is crucial for the conservation of biodiversity. Stream fishes in metapopulations are particularly sensitive to habitat fragmentation because persistence depends on dispersal and colonization of new habitat but dispersal is constrained to stream networks. Great Plains streams are increasingly fragmented by water diversion and climate change, threatening connectivity of fish populations in this ecosystem. We used seven microsatellite loci to describe population and landscape genetic patterns across 614 individuals from 12 remaining populations of Arkansas darter ( Etheostoma cragini) in...
The project will complete an extensive mapping of coastal change along the entire coastline of the Western Alaska Landscape Conservation Cooperative (LCC). The work will provide important baseline information on the distribution and magnitude of landscape changes over the past 41 years. The extent of change to the coastline and to coastal features, such as spits, barrier islands, estuaries, tidal guts and lagoons, is known to be substantial in some areas along the coast (e.g., portions of the Yukon–Kuskokwim Delta), although the extent of change along the full Bering Sea coast is not well documented. With this analysis, changes can be summarized for different land ownerships or other units to assess the extent of...

The Green River Basin Landscape Conservation Design project (GRB LCD) is an opportunity to think, plan, and act across boundaries and jurisdictions to meet mutual goals for agreed upon conservation targets in the ecosystems of the Green River Basin. This effort is not intended to replace existing science or plans, and is not intended to undermine current management. Rather, through a collaborative process, the project will complement existing projects and partnerships by synthesizing and developing spatial data and information that is consistent and comprehensive across the Basin to provide the landscape-scale context.FY2015The Green River Basin Landscape Conservation Design project (GRB LCD) is an opportunity to...

Using a bioclimatic envelope approach, University of Alberta investigators project how the distribution and abundance of boreal forest birds across North America will respond to different scenarios of future climate-change. Investigation emphasis is on mapping and quantifying potential range expansions of boreal bird species into Arctic and subarctic regions across Alaska and Canada. The final products demonstrate a broad continental-scale overview of potential shifts in avian distribution.
This project uses previously collected ShoreZone imagery to map nearly 1,600 km of coastline between Wales and Kotzebue. With additional mapping supported by the Arctic LCC and National Park Service, this effort will complete the Kotzebue Sound shoreline, which will be included in the state-wide ShoreZone dataset. The complete ShoreZone dataset will be used to conduct a coastal hazards analysis and create maps that identify areas undergoing rapid coastal erosion and areas that are sensitive to inundation by storm surge and sea level rise.​
