The avian community of peatland habitats were surveyed along belt transects established in multiple units of Seney National Wildlife Refuge, representing peatland habitats dominated by a range of sedge to shrub cover at varying levels. Surveys were conducted during the 3-week period of mid-May to early June and again during mid-June-early July in three years (2007–2009). Three datasets are included here 1) data of presence/absence of breeding bird species detected in each 100-m segment of belt transects, 2) four-letter codes for bird species, and 3) environmental and land-cover attributes summarized for 200-m buffers around the bird-survey segments (100m x 100m), and number of years since each segment was burned,...

Woody encroachment and its effects on biodiversity in fens and grasslands has become an increasing concern in the conservation and management of plant communities. These data were collected to examine the effects of spring and summer prescribed burns on the plant community, cover, and structure in open and partially wooded fens at Seney National Wildlife Refuge, Michigan, using a before-after-control-impact design. Paired, 1-ha blocks were established in two fen areas, C3 and Marsh Creek, and data collected for two years before burning (2006-07) and three years after burning (2008-10). Treatments were C3 control, C3 spring burn (May 2008), Marsh Creek control, and Marsh Creek summer burn (July 2008); data were also...

The Yellowknife Study Area (YSA), Northwest Territories, Canada, was established in 1961 by H. W. Murdy, U.S. Fish and Wildlife Service, for the study of wetland and waterfowl ecology. The study area is located on the western edge of the Precambrian Shield and edge of the taiga and is recognized for its high wetland densities and waterfowl abundance. The region is underlain by discontinuous, warm permafrost and hence vulnerable to a warming climate. The completion of Highway 3 in early 1960s provided the first access to the region for development, research, and monitoring. The YSA is a 38-sq km area centered on Highway 3, extending 48 km in length. In the 1960s, it encompassed 262 natural ponds and 313 man-made...

The Woodworth Study Area was established by the Fish and Wildlife Service in the early 1960's as a waterfowl production area, with its primary purpose as a research area to develop information for better management of upland and wetland habitats. Scientists and staff at Northern Prairie Wildlife Research Center conducted extensive research on wetlands, upland plants, and wildlife the Woodworth Study Area during 1966–1989. While many publications have been produced from that research, the full extent of legacy data and historical information for the WSA had never been assessed. This project compiled and synthesized several core data sets on land history, vegetation surveys, and climate. Documentation of data,...

The continental population of scaup ( Aythya affinis and A. marila) fell to >30% below the 1955-2008 average, and ~3 million birds below the North American Waterfowl Management Plan (NAWMP) goal of 6.3 million. Reviews of long-term databases noted a decrease in the sex and age ratios (number of females relative to males and number of immatures relative to adults, respectively) of lesser scaup in the U.S. harvest. These results indicate that recruitment and female survival of lesser scaup has declined during this period. Recruitment is the product of several demographic rates, including female survival during the breeding season, breeding propensity, nesting success, and duckling survival. Previous life-cycle models...
