The Integrated Ecosystem Model (IEM) for Alaska and Northwest Canada Project integrated existing models of vegetation, disturbance, and permafrost into one complete ecosystem model for the state of Alaska and Northwest Canada.The final synchronized model will integrate existing climate, vegetation, disturbance, hydrology, and permafrost models to improve understanding of potential landscape, habitat and ecosystem change. The project’s (September 1, 2011 through August 31, 2016) primary goal was to develop the IEM modeling framework to integrate the driving components for and the interactions among disturbance regimes, permafrost dynamics, hydrology, and vegetation succession/migration for Alaska and Northwest Canada....
The purpose of this project is to provide better information to industry and regulatory agencies regarding the likely locations of polar bear dens. This project integrates snow physics, high-resolution digital elevation data, and bear biology to produce more refined and accurate maps predicting suitable polar bear den habitat than are currently available. The work consists of data gathering, consultation between snow and bear scientists, modeling, and sensitivity studies to understand the various factors influencing den location and evolution along the Beaufort Coast.The proposed work is intended to refine current methods of identifying polar bear denning sites by incorporating higher-resolution topographic data...
Water temperature in lakes and lagoons plays a key role in hydrology, water quality, and habitat suitability for aquatic organisms. The purpose of this project is to provide land and resource managers with information related to the past, present, and future temperature trends in lake surface waters in western Alaska. Through a combination of remote sensing, in situ data collection, model development, we will analyze similarities and differences related to spatial and temporal patterns of lake surface temperatures in western Alaska from 1985 to 2100. ‚Äč
In recent years, Alaska has seen the largest (2004), second largest (2015), third largest (2005) and sixth largest (2009) fire years since 1940, and observed increases in area burned in Canada during the last four decades are linked with warming summer season temperatures. To the surprise and concern of fire and resource managers, some of these fires burned across fire scars from the previous decade or decades, an uncharacteristic phenomenon in boreal forests. This project is assessing the ecological and management implications of repeat fires. This funding to the National Park Service and USGS is contributing to a large effort to model the conditions under which new fires burn into older fires, the behavior of...
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 Imiq Hydroclimate Database houses hydrologic, climatologic, and soils data collected in Alaska and Western Canada from the early 1900s to the present. This database unifies and preserves numerous data collections that have, until now, been stored in field notebooks, on desktop computers, as well as in disparate databases. Synthesizing and analyzing the large-scale hydroclimate characteristics of this important climatic region have been made easier with this searchable database. The data, originally collected in a Microsoft SQL Server 2008 relational database, has been migrated to an open source PostgreSQL and PostGIS environment. The Imiq Data Portal provides public access to portions of the Imiq Hydroclimate...

The Terrestrial Environmental Observation Network (TEON) is intended to meet the need for a sustainable environmental observing network for northern Alaska. The TEON plan proposes collection of a time series of specific environmental variables in seven representative watersheds across northern Alaska. The Kuparuk River watershed is central to this plan both because of its location that bisects Alaska’s North Slope and its record of hydroclimatic data and research now surpassing 30-yrs. Nested catchments within and adjacent to this sentinel Arctic river system integrate climate and landscape responses from the Brooks Range foothills (Imnavait Creek and Upper Kuparuk River) to the Arctic Coastal Plain (Putuligayuk...

Species populations are in a state of flux due to the cumulative and interacting impacts of climate change and human stressors across landscapes. Invasive spread, pathogen outbreaks, land-use activities, and especially climate disruption and its associated impacts—severe drought (see Figure 3 or the GPLCC), reduced stream flow, increased wildfire frequency, extended growing season, and extreme weather events—are increasing, and in some cases accelerating. These impacts are outpacing management and conservation responses intended to support trust species and their critical habitats. Our common goal is to craft successful adaptation strategies in the face of these multiple, interacting drivers of environmental change....

LCC funding for this project helped maintain a network of hydrology monitoring sites in a representative watershed of the Arctic Coastal Plain. The work was conducted within the context of climate change and impending oil and gas activities in the region, the latter of which is the impetus for focusing on the Fish Creek watershed. The project included two monitoring components:1) Beaded Stream & Lake Hydrology Monitoring (dominant habitat type within the watershed): in 6 stream/lake complex watersheds (Redworm, Hannahbear, Blackfish, Crea, Oil, and Bills creeks), continuous water level and temperature (in lakes, streams, and confluences), discrete discharge measurements, and continuous water quality (specific conductivity,...
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...
Landscape conservation design is an opportunity for the U.S. Fish and Wildlife Service’s National Wildlife Refuge System (NWRS) to work collaboratively with partners to develop and implement a landscape approach that ensures our priority resources will have the capacity to cope with and respond to future change. This research models patterns of climate connectivity to map linkages among protected areas that promote long-term landscape connectivity across Alaska and northwest Canada under projected climate change. Using spatial data on current land use and climate patterns, and circuit theory-based connectivity modeling approaches, this research identifies corridors that follow climate gradients and avoid human modified...

This project provides a better understanding how linkages among surface-water availability, connectivity, and temperature mediate habitat and trophic dynamics of the Fish Creek Watershed (FCW). These interrelated processes form a shifting mosaic of freshwater habitats across the landscape that can be classified, mapped, understood, and modeled in response to past and future climate and land-use change in a spatial and temporal context. Developing scenarios of freshwater habitat change in this context provides managers and scientists with a flexible template to evaluate a range of potential responses to climate and land-use change. Applying this approach in the FCW is made feasible because of the availability of...
Arctic wetlands, where millions of local and migratory birds nest, are composed of a mosaic of ice wedge polygons, non-patterned tundra, and large vegetated drained thaw lake basins. Regional climate projections suggest that evapotranspiration, rainfall, and snowfall will increase, making it difficult to predict how surface water distribution might change and how habitats for the invertebrate resources used by waterbirds will be impacted. This study will focus on evaluating how climate change will affect the invertebrate community, and whether the change in climate (through changes in hydrology and surface energy balance) could induce a trophic mismatch that might alter the growth and survival of shorebird young....
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...

One of the leading models for helping to understanding temperature and precipitation –PRISM—Parameter-elevation Regressions on Independent Slopes Model—is used in Alaska and parts of Canada as input data in projections that seek to describe future scenarios of change.Currently no PRISM data are available for Northwest Territories. Researchers will develop fine scale PRISM data – 800 meter grids— for the territory. With common data across the region, scientists can better compare scenario planning across the boreal forest. The project is a collaboration among the NWB LCC, the Northwest Territories government, Agriculture Canada and Oregon State University.
Historically, available polar bear den habitat models have been based primarily on the presence of topographic features capable of capturing drifting snow. In any given season, however, the availability and precise location of snowdrifts of sufficient size to accommodate a bear den depends on the antecedent snowfall and wind conditions, and these vary from one year to the next. Thus, suitable topography is a necessary pre-condition, but is not sufficient to accurately predict potential den sites in a given year. To satisfy the requirements of agency and industry managers what is needed is a user-friendly decision-support tool that takes into account the current fall and early-winter meteorological conditions, and...
The Yukon-Kuskokwim Delta (YKD) encompasses the southernmost, warmest parts of the arctic tundra biome and is renowned for its high biological productivity and large subsistence-based human population. Ice-rich permafrost currently is widespread and strongly influences terrestrial and aquatic habitats, including local topography, vegetation, soil hydrology, and the water balance of lakes. Ground temperatures are near the freezing point, however, and recent projections indicate that the YKD is poised for widespread loss of permafrost by the end of this century. This has implications for the region’s extensive and heretofore stable terrestrial and aquatic habitats. Tundra wildfire is a common ecological “pulse” disturbance...

Mid-winter icing events have the potential to lead to population declines of grazing caribou and to some species of small mammals due to reduced survival and reproduction associated with restricted access or lack of forage. Population-level effects of icing events remain unclear partly due to limited information on icing events in Alaska. The assessment results provide a baseline data set and remote sensing method, both of which have broad applicability, allowing the community of users to better understand the recent past, better link changes in ecological drivers and responses of wildlife populations, and aid in planning for the future.
Understanding snow conditions is key to developing a better understanding of hydrologic, biological, and ecosystem processes at work in northern Alaska. The required snow datasets currently do not exist at spatial or temporal scales needed by end users such as scientists, land managers, and policy makers. There are a wide variety of snow datasets that may be generated by this project. The list of desired datasets will be refined based on input from potential end users. However, outputs could include daily spatial distributions spanning the spatial and temporal domains of interest of the following variables: air temperature, wind speed and direction, relative humidity, surface (skin) temperature, incoming solar radiation,...
