Alaska is experiencing a wide range of impacts from climate change and communities seek adaptive strategies that encourage wellness and sustainability. This report documents climate change impacts as described by community residents and climate change effects or potential effects as interpreted through the lens of public health. It is the seventh report in a series describing climate change in communities across Alaska, and the third report to focus on the Bristol Bay region. In the Alutiiq and Yupik community of Levelock Alaska, residents report changes to the weather, seasons, landscape, plants, and wildlife with important implications for community health. Understanding local impact of climate change is important...

Native grasslands have been altered to a greater extent than any other biome in North America. The habitats and resources needed to support breeding performance of grassland birds endemic to prairie ecosystems are currently threatened by land management practices and impending climate change. Climate models for the Great Plains prairie region predict a future of hotter and drier summers with strong multiyear droughts and more frequent and severe precipitation events. We examined how fluctuations in weather conditions in eastern Colorado influenced nest survival of an avian species that has experienced recent population declines, the Mountain Plover (Charadrius montanus). Nest survival averaged 27.2% over a 7-yr...

Landscape Design has been described as the bridge between landscape ecology and conservation delivery. It recognizes the need for humans to live and work in the landscape and it seeks to understand the patterns and the underlying processes of those patterns.

These data represent the long term average (27 year) amount of crane energy days (CED) available in wetlands. CEDs were calculated in the same way as wetland duck energy days describe above except that different habit energy density values were used. Based on the PLJV waterbird plan (2008) Appendix A, we estimated wetland CED density values for wetland habitats by dividing energetic carrying capacities for waterfowl by 3.37 to reflect the difference in mean body mass between mallards and sandhill cranes.

Conceptually, we overlaid down-scaled Global Climate Model data to assess climatic conditions with fish species thermal tolerance data and potential barrier to movement data to predict future fish species distributions and/or identify species that may be vulnerable to climate projections. These species distribution data, of 13 fish species at 3 different time frames, were constructed from species distribution models containing only current, projected 2050, and projected 2099 air temperature (obtained from The Nature Conservancy Climate Wizard tool) and average United States Geological Survey hydrologic unit-8 daily discharge. Average daily discharge was calculated as the average discharge of all streamgages within...

Researchers from the University of Alaska (UAF), The NatureConservancy, and U.S. Fish and Wildlife Service will use‘climate envelope’ models (i.e., models that infer a species’environmental requirements from locations where they arecurrently found) to explore how patterns in temperature,precipitation, and landcover (i.e., climate-biomes) may shift as aresult of changing climate.
Final report detailing the results of the climate change vulnerability assessment conducted by the Wildlife Conservation Society.The specific goals of this assessment were to: provide a climate change vulnerability ranking for selected Arctic Alaskan breeding bird species; evaluate the relative contribution of specific sensitivity and exposure factors to individual species rankings; consider how this assessment may be integrated with other approaches; and appraise the effectiveness of the NatureServe Climate Change Vulnerability Index (CCVI) tool.
The Savannah Sparrow has a widespread breeding range across North America from thesouthern U.S. to Arctic Alaska. This species will breed in open habitats ranging from meadows,cultivated fields, grazed pastures, roadsides, coastal grasslands and tundra (Wheelwright andRising 2008). On the coastal plain of Arctic Alaska, tundra nesting habitat is often associatedwith stream/river drainages, nesting on the ground often hidden under low shrubs (Wheelwrightand Rising 2008). During the breeding season they forage in a wide range of habitats on a varietyof insect prey although seeds and other vegetative matter are also consumed (Wheelwright andRising 2008). Savannah Sparrows are short-distance migrants and winter in the...
The Snowy Owl, a conspicuous and majestic bird of the circumpolar arctic, is an efficient hunterof small mammals in tundra environs. In years of high lemming numbers they will focus on thisabundant food source but will readily switch to a wide variety of other prey when lemmings arescarce (Parmelee 1992). Their breeding range in Alaska is generally restricted to the ArcticCoastal Plain, typically nesting in more upland tundra habitats, although they often, though notexclusively, forage in wetter tundra (Parmelee 1992). Snowy Owls are unpredictable migrantsand will sometimes “invade” portions of southern Canada and the northern contiguous US, inwinters when lemmings are scarce in the Arctic. The current global population...
The Common Eider, a large sea duck, is more closely tied to marine environments than are manyother sea ducks. On the Arctic Coastal Plain of Alaska this species nests primarily on barrierislands and peninsulas of the Arctic Coastal Plain (a small proportion of the total area) while inother parts of its range they select quite varied nesting sites (Goudie et al. 2000). Common eidersdepend on a marine prey base, eating invertebrates (primarily mollusks and crustaceans) bydiving to the sea floor. Alaskan breeders spend their winters nearby in the Bering Sea, Gulf ofAlaska, and off Russia’s Chukotka Peninsula (SDJV 2004). Current Arctic Coastal Plainpopulation is estimated at approximately 2,000 (Dau and Bollinger 2009).
Results indicate that the regions most vulnerable to ecological shifts under the influence of climate change are likely to be the interior and northern mountainous portions of Alaska; the northern Yukon; and much of the Northwest Territories. Although the A1B and A2 emissions scenarios predict more cliome shift overall, as compared to the more conservative B1 scenario, the patterns hold true across all three. Notably, there are no areas of the NWT predicted to retain their current cliomes.
The Bristol Bay region represents an area of transition between the maritime climate of the southern coast and the continental climate of the Interior and Copper River Basin. These regions are largely protected by mountains areas and do not have a strong maritime influence. Temperatures are moderate and sea ice does form in the Bristol Bay but complete freeze-up of these waterways is not common. Low winter temperatures are below 0 degrees F with events below -20F. Summer temperatures are generally in the mid 60s with only a few days above 80. Highest precipitation is in August and September (Shulsky and Wendler 2007). The following table is a scoping tool that can be used to begin to evaluate community vulnerability...

This report documents climate change impacts and potential impacts as described by the local people and interpreted through the lens of public health. It is the sixth report in a series describing climate change across Alaska, and the first report to focus on the Bristol Bay Region. In the Yupik and Aleut community of Pilot Point residents report changes to the weather, landscape, plants and wildlife. Extreme weather events are thought to be more common, the timing of seasons is more unpredictable, erosion to shorelines is occurring at a rapid rate, and consequentially, vulnerability to flooding is increasing. Identified health concerns include food security, damage to health-critical infrastructure, injury and...
