Plant data were collected on 16, 1-ha experimental blocks in C3 and Marsh Creek units of Seney National Wildlife Refuge, 2006-2010. The percent cover of each plant taxon, moss as a group, and open area was recorded sing a modified line-intercept method for each of 25 sampling points within a block. Sampling points were equidistantly spaced, with 5 points spaced 25 m apart along each of 5 transects also spaced 25 m apart within each sampling block. Within each unit, we selected 4 pairs of blocks representing sedge-shrub habitat, with one of the pair assigned to spring burning (C3, May 2008) or summer burning (Marsh Creek, 2007 and 2008). This before-after-control-impact design provided for data collection two growing...

In association with plant cover data, data on litter depth, water depth, and graminoid height were collected on 16, 1-ha experimental blocks in C3 and Marsh Creek units of Seney National Wildlife Refuge, 2006-2010. Within each unit, we selected 4 pairs of blocks representing sedge-shrub habitat, with one of the pair assigned to spring burning (C3, May 2008) or summer burning (Marsh Creek, 2007 and 2008). This before-after-control-impact design provided for data collection two growing seasons before the burn (2006, 16 blocks; 2007, 15 blocks) and two-three growing seasons (2008, 2009, and 2010; 14 blocks) after burning; the unburned plot of each pair served as the control, and the burned plot of each pair the treatment....

This data set represents the extent, approximate location and type of wetlands and deepwater habitats in the Alaska, United States. These data delineate the areal extent of wetlands and surface waters as defined by Cowardin et al. (1979). Certain wetland habitats are excluded from the National mapping program because of the limitations of aerial imagery as the primary data source used to detect wetlands. These habitats include seagrasses or submerged aquatic vegetation that are found in the intertidal and subtidal zones of estuaries and near shore coastal waters. Some deepwater reef communities (coral or tuberficid worm reefs) have also been excluded from the inventory. These habitats, because of their depth, go...

This data set represents the extent, approximate location and type of wetlands and deepwater habitats in Southeast Alaska. These data delineate the areal extent of wetlands and surface waters as defined by Cowardin et al. (1979).
