The 25,000 km of shoreline in southeast Alaska was surveyed for waterbirds by fixed-wing aircraft in summer and winter during the period 1997 to 2002. A ground/boat survey double sampled 20% of the summer habitat and 5% of the winter habitat to adjust and enhance the air survey. The most abundant species during the summer surveys, with visibility correction factors applied, were gulls (Larus spp.; 306,200, CV = 0.004), scoters (Melanitta spp.; 185,700, CV = 0.004), and Harlequin Duck (Histrionicus histrionicus; 34,640, CV = 0.03). The most abundant species observed during the winter surveys were goldeneyes (Bucephala islandica and B. clangula; 121,920, CV = 0.01), gulls (105,000, CV = 0.01), Mallard (Anas platyrhynchos;...

This vector polygon feature class was developed from the Upper Midwest & Great Lakes Landscape Conservation Cooperative's Coastal Conservation Working Group (CCWG) "Designing the Coastal Wetlands of Tomorrow" September 6th, 2017 stakeholder workshop. The polygon features represent potential areas of coastal wetland opportunities and were derived from paper maps marked up by workshop participants that they believed to be areas of opportunity for coastal wetland protection (maintain and protect current wetlands), restoration (add wetlands or increase size of a wetland), or enhancement (improve the quality of a wetland). The CCWG is particularly interested in these opportunities to partner and provide support for coastal...
