Western Arctic Coastal Plain, IfSAR DSM Mosaic Footprint More than 35,000 lakes larger than 0.01 sq. km. were extracted from an airborne interferometric synthetic aperture radar (IfSAR) derived digital surface model acquired between 2002 and 2006 for the Western Arctic Coastal Plain of northern Alaska. The IfSAR derived lake data layer provides an improvement over previously available datasets for the study area since it is more comprehensive and contemporary. Attributes assigned to the IfSAR-derived lake dataset include: area, lake elevation, elevation in 10, 25, 50, and 100 m buffers around a lake perimeter, the difference in elevation between the lake and these various buffers, whether a particular lake had a detectable drainage gradient exceeding 1.2 m, whether a...

Thisspecies nests primarily on precipitous cliff faces and typically utilizes nests built by other species(particularly Common Raven, Golden Eagle, and Rough-legged Hawk) (Booms et al. 2008).Gyrfalcon main prey includes bird species ranging in size from passerines to geese whileptarmigan are the preferred prey. Although not well documented, in winter this species movessouth throughout Canada and sometimes into the northern lower 48. Current population on theNorth Slope (tundrius subspecies) is estimated at 250 breeding pairs (USFWS 2000).

In Alaska, this species typically nests in wet tundra near water’s edge.It differs from the Red Phalarope in that it breeds further inland and at higher elevations (Rubegaet al. 2000). Like other phalaropes, this species depends on aquatic food sources for much of itsdiet (Rubega et al. 2000). Red-necked Phalaropes spend winter at sea in tropical waters in largenumbers off the west coast of South America (Rubega et al. 2000). Current North Americanpopulation estimate is 2.5 million with a declining trend (Morrison et al. 2006).

Snow Free Date is defined as day of the end of the core snow period(day of year). The core snow season is defined to be the longest period of continuous snow cover in each year. The dataset was generated by the Arctic LCC SNOWDATA: Snow Datasets for Arctic Terrestrial Applications project.“Day-of-year” (doy) output is expressed in Ordinal dates (“1” on 1 January, and “365” on 31 December). Dates have not been corrected for leap years. This output is appropriate for display purposes, as it is readily interpreted as calendar day of year.

A framework that dynamically links these models has been defined and primaryinput datasets required by the models have been developed.

This species breeds in open scrubby areas; willow, birch, andalder thickets, stunted spruce, open tundra with scattered shrubs, often near lakes or bogs(Naugler 1993). In summer American Tree Sparrows consume a wide variety of animal prey(primarily both larval and adult insects). Alaskan birds are short-distance migrants and winter intemperate North America (Naugler 1993). This species’ population is very large (>10 million)although the overall population has undergone a small (statistically insignificant) decrease overthe last 40 years in North America (Butcher and Niven 2007).

This species nests in higher densities in the western portion of thecoastal plain compared to the east (Johnson et al. 2007). They prefer wet grassy meadows fornesting often showing an affinity for sedge-willow, wet meadow or sedge marsh along drainagesor near ponds (Takekawa and Warnock 2000). Long-billed Dowitchers generally migrate west ofthe Mississippi River and winter primarily along the Pacific and Gulf Coasts of North Americainto Mexico (Takekawa and Warnock 2000). Current population estimate of the North Americanpopulation is 400,000 (Morrison et al. 2006).
