We propose to use GPLCC capacity funds to help create The Nebraska Conservation Science Partnership (NCSP), a cooperative effort among the Nebraska Game and Parks Commission, the Rainwater Basin Joint Venture (RWBJV), and the Nebraska Cooperative Fish and Wildlife Research Unit (NCFWRU). This partnership will provide capacity to analyze climate data relative to impacts on fish and wildlife within the Great Plains LCC, integrate existing habitat assessments, model species-habitat relations, and evaluate the potential impacts of land use change management activities, initially focusing primarily on wetland habitats. The funding requested from the GPLCC will be leveraged with funds from the RWBJV and the USGS Climate...
This data product consists of a database of population change and abundance estimates for North American birds, estimated from North American Breeding Bird Survey (BBS) data. Data are presented for 548 species of birds in 4 spreadsheets containing trend estimates and annual indices for 2 time periods. Estimates are derived for each species using the 1 of 4 alternative models, and a cross-validation model selection procedure was used to select the best model for each species.

This data product consists of a database of population change and relative abundance estimates for North American birds, estimated from North American Breeding Bird Survey (BBS) data. Data are presented in 6 separate spreadsheets for 2 methods of trend summary and 3 time periods for 548 species of birds. Metadata for the BBS data used to produce these estimates is available from a USGS ftp site (ftp://ftpext.usgs.gov/pub/er/md/laurel/BBS/DataFiles/). Metadata associated with this data product provides information specific to the analysis results.

The data set consists of data to evaluate bias in roadside surveys of secretive marsh birds in 2008 and 2009 in wetlands in the Prairie Pothole Region of Minnesota, North Dakota, and South Dakota during three survey periods (survey number). The data set includes detection values (species heard, species seen, species seen and heard) of seven focal marsh bird species (four-letter alpha codes and scientific names [genus and species]) by paired basin regime (temporary, seasonal, semipermanent, lake) locations using play-callback recordings and passive listening, and the detection distance to each species. In conjunction with surveys of wetland birds, the following location, weather and wetland features were recorded:...
This data product consists of raster digital data of population change and abundance estimates for 520 species of North American birds estimated from North American Breeding Bird Survey (BBS) data. Estimates of trend (yearly % change) from 1966-2022 and mean abundances for the interval 2018-2022 are spatially smoothed from data for each species collected on BBS routes. Metadata for the BBS (https://www.sciencebase.gov/catalog/item/64ad9c3dd34e70357a292cee) and BBS regional analyses (https://www.sciencebase.gov/catalog/item/650325c9d34ed30c2058be3b) provide general information on the survey and survey analyses; these metadata provide information specific to the mapping analysis results.
This data product provides summary information, by species, of changes in relative visibility of birds (phenology effects) through the April - July time period in which the North American Breeding Bird Survey (BBS) is conducted. Data are presented for 408 species of birds. Seasonal phenology effects are presented for selected latitudes and years, documenting changes in visibility and a variety of statistics to allow users to assess the significance of those effects. Results are presented as csv files, stored in zip files by first letter of the species common name and a single zip file containing csv files for 408 species. Links are provided to Child Items containing additional information in species-specific R...

Breeding Bird Density,
Expert knowledge-based species-habitat relationships are used extensively to guide conservation planning, particularly when data are scarce. Purported relationships describe the initial state of knowledge, but are rarely tested. We assessed support in the data for suitability rankings of vegetation types based on expert knowledge for three terrestrial avian species in the South Atlantic Coastal Plain of the United States. Experts used published studies, natural history, survey data, and field experience to rank vegetation types as optimal, suitable, and marginal. We used single-season occupancy models, coupled with land cover and Breeding Bird Survey data, to examine the hypothesis that patterns of occupancy conformed...

This data product provides summary information of changes in relative visibility of 408 species of North American birds (phenology effects) through the April - July time period in which the North American Breeding Bird Survey (BBS) is conducted. These phenology effects are presented for selected latitudes and years, documenting changes in visibility and a variety of statistics to allow users to assess the significance of those effects. Results are presented as R data sets as supplemental material to primary results presented as csv files.
Abstract (from https://www.ncbi.nlm.nih.gov/pubmed/26990459): There is intense interest in basic and applied ecology about the effect of global change on current and future species distributions. Projections based on widely used static modeling methods implicitly assume that species are in equilibrium with the environment and that detection during surveys is perfect. We used multiseason correlated detection occupancy models, which avoid these assumptions, to relate climate data to distributional shifts of Louisiana Waterthrush in the North American Breeding Bird Survey (BBS) data. We summarized these shifts with indices of range size and position and compared them to the same indices obtained using more basic modeling...

Data are presented for 408 species of birds. Seasonal phenology effects are presented for selected latitudes and years, documenting changes in visibility and a variety of statistics to allow users to assess the significance of those effects. This Child Item is a supplement to the Sciencebase Data Release "Phenology effects in the North American Breeding Bird Survey," in which the results are presented in summarized graphical form in species-specific pdf files.
These data indicate the modeled density of greater sage grouse for 75% of birds in 26.9% of their overall range. This dataset was provided by BLM with minimal metadata.
The Latitude is the average latitude of all 0.5 degree cells covering the eastern United States and southeastern Canada between longitude 60W and 102 W and latitude 24N and 49N, weighted by the unconditional probability of occupancy of Louisiana Waterthrush. Values given for the years 1997 to 2013. The Latitude_SE is the estimated standard error for the Latitude. Description of the data and analysis used to generate these values is given in: Clement, M.J., J.E. Hines, J.D. Nichols, K.L. Pardieck, D.J. Ziolkowski Jr. 2016. Estimating indices of range shifts in birds using dynamic models when detection is imperfect. Global Change Biology 22:3273-3285. doi: 10.1111/gcb.13283.
