Information on the nature and distribution of permafrost is critical to assessing the response of Arctic ecosystems to climate change, because thawing permafrost under a warming climate will cause thaw settlement and affect micro-topography, surface water redistribution and groundwater movement, soil carbon balance, trace gas emissions, vegetation changes, and habitat use. While a small-scale regional permafrost map is available, as well as information from numerous site-specific large-scale mapping projects, landscape-level mapping of permafrost characteristics is needed for regional modeling and climate impact assessments. The project addresses this need by: (1) compiling existing soil/permafrost data from available...

The primary objective of this project is to bring together Hawaii’s climate change scientists, Molokai’s traditional fishpond managers, and other natural resource managers to share scientific and cultural knowledge and work together as a team to identify adaptive management strategies for two of Molokai’s ancient fishponds. We will accomplish this through a short series of workshops. A secondary objective is to form new and strengthen existing partnerships so we can pool resources and better respond to climate change as an island. We will incorporate workshop results into our strategic plan for the ponds and upland areas, revise our K-6 educational curriculum, create a climate change video featuring Moloka’i kupuna,...
The South Atlantic Conservation Blueprint is a living spatial plan to conserve natural and cultural resources for future generations. It identifies shared conservation priorities across the South Atlantic region. The first Blueprint, Version 1.0, was released in March 2014. Blueprint 1.0 was based on a combination of expert input and partner plans and used a spatial scale of HUC-12 subwatersheds in the terrestrial environment and outer continental shelf lease blocks in the marine environment. More than 300 people from 85 organizations were actively involved in developing this version of the Blueprint.

Geographic relationships among energy infrastructure development, regional economic linkages, and the environment is crucial for understanding the impacts of Appalachian energy extraction activities and for regional planning efforts focused on the ecosystem services that may be affected. The U.S. Energy Information Administration (EIA) provides impartial and independent data on the nation’s energy infrastructure, its sources, flows, and end uses, as well as forecasts and outlooks. Location information for specific extraction activities, as well as power plants and other supply chain components, can help reveal the regional nature of specific impacts and the often large distances between those effects and end-use...

The Appalachian Mountains provide a multitude of habitats that are essential for hundreds of breeding, migrant, and wintering bird species. Its rugged terrain is dominated by forest and woodlands that span 15 states and contain several major eastern rivers that are heavily relied upon by waterfowl. But historical and current land-use changes, environmental disturbances, and other factors are resulting in population declines of more than 1/3 of bird species that breed and winter in the region. Coordinated action among local, state, federal, and other partners is essential to reverse these trends.The Appalachian Mountains Joint Venture (AMJV) is one of 18 habitat Joint Venture partnerships in the United States. It...

This dataset provides a watershed index of surface drinking water importance, a watershed index of forest importance to surface drinking water, and a watershed index to highlight the extent to which development, fire, and insects and disease threaten forests important for surface drinking water. This symbology for this layer is based on the index value for insect and disease threat to forests which are important to surface drinking water on a range from 1-100.

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.

The Spectacled Eider is a medium-sized sea duck with males easily recognized by their striking“clown-like” head plumage. This species was listed as threatened in 1993 under the EndangeredSpecies Act as it has suffered severe population declines in western Alaska. The Arctic CoastalPlain population may also be declining. In Arctic Alaska, breeding Spectacled Eiders use riverdeltas and wet tundra habitats, including drained-lake basins, flooded wetlands, and islets withina matrix of thaw lakes for both nesting and foraging (Petersen et al. 2000). During the breedingseason, their diet consists primarily of both adult and larval aquatic insects (Petersen et al. 2000).Alaskan breeders spend their winters offshore in...

This raster, created in 2010, is output from the Geophysical Institute Permafrost Lab (GIPL) model and represents simulated mean annual ground temperature (MAGT) in Celsius, averaged across a decade, at the base of active layer or at the base of the seasonally frozen soil column. The file name specifies the decade the raster represents. For example, a file named MAGT_1980_1989.tif represents the decade spanning 1980-1989. Cell values represent simulated mean annual ground temperature (degree C) at the base of the active layer (for areas with permafrost) or at the base of the soil column that is seasonally frozen (for areas without permafrost). If the value of the cell is negative,the area has permafrost and the...

This raster, created in 2010, is output from the Geophysical Institute Permafrost Lab (GIPL) model and represents simulated active layer thickness (ALT) in meters averaged across a decade. The file name specifies the decade the raster represents. For example, a file named ALT_1980_1989.tif represents the decade spanning 1980-1989. Cell values represent simulated maximum depth (in meters) of thaw penetration (for areas with permafrost) or frost penetration (for areas without permafrost). If the value of the cell is positive, the area is underlain by permafrost and the cell value specifies the depth of the seasonally thawing layer above permafrost. If the value of the cell is negative, the ground is only seasonally...

Activity 1. Quantify viability of corridors using temporal sampling: past, present, future. As large-scale wind patterns change, the viability of flyways in the Pacific hemisphere is likely to change. This project will evaluate the tail/headwind components for flight routes from Alaska to sites in the South Pacific (documented godwit and curlew flight tracks) by sampling 50-year timeslices to determine whether the present climatology is more or less favorable than the past (paleoclimate) periods or the projected future (late 21st century). The project will determine whether other flight corridors may have been more advantageous in the past or future than during the present period.Activity 2. Assessment of optimization...
