Breeding bird species in peatland habitats, Seney NWR, 2007-2009
공공데이터포털
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, based on refuge fire records.These data support the a publication examining factors influencing the bird community in peatlands.
The influence of local- and landscape-level factors on wetland breeding birds in the Prairie Pothole Region of North and South Dakota dataset
공공데이터포털
The data set consists of data collected in 1995, 1996, and 1997 in wetlands in the Prairie Pothole Region of North Dakota and South Dakota. The data were summarized and used in the analysis for a U.S. Geological Survey Open File Report entitled: The influence of local- and landscape-level factors on wetland breeding birds in the Prairie Pothole Region of North and South Dakota. The data consist of two data sets. A species data set includes the common names, scientific names (species and genus), and four-letter alpha codes for 133 bird species observed during the three-year study. The bird abundance data set includes the abundance of wetland birds by wetland class (temporary, seasonal, semipermanent, permanent, alkali), wetland type (natural or restored), and landowner group (private or federal). In conjunction with surveys of wetland birds, the following wetland variables also were recorded: wetland size, date (julian date), location (easting and northing), local-level habitat variables (percent coverage of open water, emergent vegetation, wet meadow, and shoreline/mudflat) and landscape-level habitat variables (number of wetlands and percent cover of grass and wetlands within 800 m of a wetland).

Waterfowl Nests in Native- and Tame-Seeded Conservation Fields, North and South Dakota, 2002-2003
공공데이터포털
This dataset describes features of 2941 duck nests that were found in the Prairie Pothole Region of North and South Dakota during 2002-2003. Nest features include estimated initiation date, incubation stage and status as active. The dataset accompanies a scientific journal article describing an evaluation of the density and success of duck nests in conservation fields in 36 study areas that were seeded with native or tame grasses. Field features in this dataset include seeding treatment, planted area, and area of grassland patch.

Fledging times of grassland birds in North Dakota and Minnesota
공공데이터포털
The data set provides information on the fledging times of passerine grassland birds. Data were collected from video surveillance of 70 nests of 9 bird species that nested in grasslands of Minnesota and North Dakota, USA. The data include year, unique nest number, species, date and time of fledging by nestling.
