Climate change refers to change over time due to natural variability or as a result of human activity (IPCC, 2008). 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 local people 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 across Alaska, and the second report to focus on the Bristol Bay region, the first being in the community of Pilot Point. In the Dena’ina community of Nondalton, residents report changes to the weather, the landscape,...

Climate change is expected to impact the thermal regimes of streams and otherfreshwater ecosystems (Schindler 2001, Malmqvist and Rundle 2002, Poff et al. 2002). Whileincreased air temperatures will have direct effects on water temperature, indirect effects due tochanges in precipitation patterns, groundwater characteristics, and flow regimes (Perkins et al.2010) may have much larger effects. We explored 1) how variation in hydrologicalcharacteristics of streams mediate their thermal regimes, 2) how geomorphic features ofwatersheds regulated stream water sources and, therefore, thermal characteristics, and 3) whetherpatterns of thermal variation among streams correlate with the life-history characteristics ofPacific...

Southwest Alaska is one of the fastest warming regions on Earth and its aquatic resources are at distinct risk from changing climate. Previous work has demonstrated that a variety of physical and biological processes are sensitive to changing climate regimes in this region, including those that support wildlife and fisheries that are of substantial importance for subsistence and commercial activities. This collaborative project resulted in the compilation of a database of existing stream, river and lake temperatures that is unmatched anywhere else in Alaska in terms of its spatial and temporal coverage. Analysis of these data resulted in refinement of the monitoring plan developed to characterize thermal responses...

An assessment of climate change impacts on communities in the Bering Strait Region was conducted by three tribal organizations, the Alaska Native Tribal Health Consortium, the Norton Sound Health Corporation, and Kawerak Inc. The purpose was to evaluate the broad range of climate change impacts observed by community members, to identify potential health effects, and to raise awareness and provide guidance that community leadership and the tribal health system could use to help guide planning and intervention activities. This presentation will explore the process and review findings from the project as well as providing an overview of some of the recommendations.

These raster datasets represent historical stand age. The last four digits of the file name specifies the year represented by the raster. For example a file named Age_years_historical_1990.tif represents the year 1990. Cell values represent the age of vegetation in years since last fire, with zero (0) indicating burned area in that year. Files from years 1860-2006 use a variety of historical datasets for Boreal ALFRESCO model spin up and calibration to most closely match historical wildfire dynamics.

Webinar 1: Alaska’s National Hydrography Dataset (NHD), the digital data layer that depicts the location of lakes and streams, was originally created from the 1950’s topographic maps. With funding support from the LCC Network, this project focused on establishing a statewide framework to improve the hydrography mapping and stewardship in Alaska. This will be achieved through the creation of a statewide system to make digital mapping data updates accessible and affordable, and through the creation of a statewide hydrography mapping coordinator position to synchronize updates and guide hydrography mapping development. This framework will allow agencies and organizations to greatly improve their hydrography mapping...
As Alaskans continue to feel the impacts of a changing climate, the need for resource managers to understand how these changes will alter aquatic systems and fisheries resources grows. Water temperature data collection has increased in recent years to begin to fill our gaps in knowledge about current thermal profiles. Many entities are collecting temperature data for a variety of purposes to meet project or agency specific goals. AKOATS, the Alaska Online Aquatic Temperature Site, is a comprehensive statewide inventory of current (n=413) and historic (n=398) continuous monitoring locations for stream and lake temperature using a common set of attributes. Data were gathered from fish biologists, hydrologists, water...

This plan establishes a framework for voluntary, network-based water temperature monitoring of salmon habitat in the Kodiak Archipelago, Alaska. The goals are to coordinate acquisition and availability of water temperature data that meets salmon management needs of cooperating organizations, meets statewide minimum data collection standards, and is publicly-accessible. The focus on monitoring water temperature of salmon habitat reflects recognition of its prominent influence on salmon at all life cycle stages; the importance of salmon to the economy and ecosystem of the archipelago; and the need to provide reliable time-series data to support development of proactive approaches to management of salmon in response...

The Integrated Ecosystem Model for Alaska project (IEM) uses down-scaled climate models as the drivers of ecosystem change to produce forecasts of future fire, vegetation, permafrost and hydrology regimes at a resolution of 1km. This effort is the first to model ecosystem change on a statewide scale, using climate change input as a major driving variable. The objectives of the IEM project are as follows; to better understand and predict effects of climate change and other stressors on landscape level physical and ecosystem processes, and to provide support for resource conservation planning.The IEM will provide resource managers with a decision support tool to visualize future landscapes in Alaska. Model outputs...

Spawning migrations of Pacific salmon (Oncorhynchus spp.) to coastal watersheds provide a rich resource subsidy to freshwater consumers. However, variation in thermal regimes and spawning activity across the landscape constrain the ability of poikilothermic consumers to assimilate eggs and carcasses. We investigated how sockeye salmon (Oncorhynchus nerka) spawning density and stream temperature affect the growth, body condition, and fatty acid composition of juvenile coho salmon (Oncorhynchus kisutch), a known egg predator, in seven tributaries of the Wood River in Southwest Alaska. We compared mean body size of juvenile coho salmon in late summer among 3–7 years per stream and found that the largest mean size occurred...

A high spatial resolution storm surge model was developed for the YK Delta area to assess biological impacts of storm surges under current and future climates. Storm surges are expected to be more frequent and more severe in the YK Delta area due to climate change and sea level rise. The biological impacts in the YK Delta due to the changed storm surges could be extreme.The model was assessed with respect to measured water level data at the coast and, where available, spatial extent of inundation, for 6 storms from the period 1992 to 2011. In total, inundation projections from 9 historical storms (5 from the assessment + 4 others) were developed. For each storm, an spatial inundation index (time-integral of water...

An important unresolved question is how populations of coldwater-dependent fishes will respond to rapidly warming water temperatures. For example, the culturally and economically important group, Pacific salmon (Oncorhynchus spp.), experience site-specific thermal regimes during early development that could be disrupted by warming. To test for thermal local adaptation and heritable phenotypic plasticity in Pacific salmon embryos, we measured the developmental rate, survival, and body size at hatching in two populations of sockeye salmon (Oncorhynchus nerka) that overlap in timing of spawning but incubate in contrasting natural thermal regimes. Using a split half-sibling design, we exposed embryos of 10 families...
Alaska’s Arctic Coastal Plain (ACP) and Yukon-Kuskokwim Delta (YKD) provide essential habitat for wildlife of management interest, including diverse communities of shorebirds and waterfowl. The low-lying ACP region is located on the North Slope of Alaska, and is rich with shallow lakes and ponds that form as a result of permafrost freeze-thaw cycles. This region is a primary nesting site for many migratory birds. The YKD, meanwhile, is a vast wetland/tundra landscape on Alaska’s remote western coast. One of the largest deltas in the world, the YKD supports millions of nesting and migrating waterfowl and shorebirds, and is the largest goose nesting habitat in North America. As climate conditions change and permafrost...

Concern about invasive species in Alaska is a growing concern, attracting attention from land managers, politicians and the public. Nearly half the new discoveries of invasive plants, animals, and insects in the state are reported by concerned individuals with a general interest in invasive species. The development of a mobile application for invasive plant identification and reporting will help enable the public to gather and share new invasive plant discoveries. This project will result in the development of a decision tool for identifying non-natives plant species, which will provide the foundation for the application. Project staff will also review user-submitted requests for identification assistance, review...
