Native grasslands have been altered to a greater extent than any other biome in North America. The habitats and resources needed to support breeding performance of grassland birds endemic to prairie ecosystems are currently threatened by land management practices and impending climate change. Climate models for the Great Plains prairie region predict a future of hotter and drier summers with strong multiyear droughts and more frequent and severe precipitation events. We examined how fluctuations in weather conditions in eastern Colorado influenced nest survival of an avian species that has experienced recent population declines, the Mountain Plover (Charadrius montanus). Nest survival averaged 27.2% over a 7-yr...

These are preliminary vegetative cover surveys for the Nebraska collected for the purpose of developing a land cover map. These data were collected by Nebraska Game and Parks Commission in coordination with the Missouri Resource Assessment Partnership (MoRAP). The overall vegetation community was recorded in addition to the dominant 3 species and percent cover of these vegetative communities: herbaceous, shrub, and woody. A photo was taken of each survey location and attached to the record.

These data represent 1 sq. mile Hexagons and are derived from the Western Governors Association Crucial Habitat Assessment Tool. The hexagons have been attributed with summary values from the datasets described above. Field names correspond to the number datasets above as follows: {1:’wetland_deds’, 2:’wetland_ceds’, 3:’cropland_ceds’, 4:’lasp_grsp_casp_suit’, 5:’lasp_grsp_suit’, 6:’riparian_suit’, 7:’mean_sat_thick_ft’, 8:’tillage_suit’, 9:’wind_suit’, 10:’ann_aq_deplet_ft’, 11:’wetland_deds_2040’, 12:’wetland_ceds_2040’, 13:’lbgrasslands_2017’, 14:’lbgrasslands_2022’, 15:’lbgrasslands_2027’, 16:’mean_sat_thick_2050_ft’, 17:’tillage_suit_2050’}. Zonal statistic attribution methods are as follows: {1:’SUM’, 2:’SUM’,...

These data represent the amount of crane energy days derived from croplands that are available within a 10km distance. These data were calculated by reclassing the NASS Cropland Data Layer to reflect energetic carrying capacity for cranes reported by Johnson et. al 2017. I.e Winter Wheat: 2588 CEDs/ ha, Corn: 1034 CEDs / ha, Sorghum: 496.5 CEDs / ha. A 10km moving windows analysis with a circular window was applied to the resulting CED raster to sum the CED values within a 10km area.
These data represent the long term average (27 year) amount of crane energy days (CED) available in wetlands. CEDs were calculated in the same way as wetland duck energy days describe above except that different habit energy density values were used. Based on the PLJV waterbird plan (2008) Appendix A, we estimated wetland CED density values for wetland habitats by dividing energetic carrying capacities for waterfowl by 3.37 to reflect the difference in mean body mass between mallards and sandhill cranes.

Inundation is a critical parameter of wetland hydrologic performance. This study uses Annual Habitat Survey data from 2004 to 2012 in the Rainwater Basin in south-central Nebraska to examine differences between the actual inundation conditions and three datasets: the National Wetland Inventory (NWI), the Soil Survey Geographic database (SSURGO), and LiDAR-derived depressions. The results show that current wetland inundated areas were well overlaid with these datasets (99.9% in SSURGO data, 67.9% in NWI data, and 87.3;% in LiDAR-derived depressions). However, the hydrologic degradation of playa wetlands was not reflected in these datasets. In SSURGO data, only 13.3% of hydric soil footprint areas were inundated and...

Redacted transcripts of open-ended focus groups discussions and follow-on questioning intended to reveal the key socioeconomic realities and hurdles that discourage landowners from enrolling in conservation programs or restoring playas. Focus groups were conducted in areas with large playa clusters as identified by PLJV’s science-based Playa Decision Support System. Researchers selected key landowners in each state for participation, and will use the focus group sessions to learn what landowners think and feel about management of their lands in general, and about conservation of playas specifically. To prepare for the focus groups, workshops were held to solicit input from conservation agencies and partners on what...

Conceptually, we overlaid down-scaled Global Climate Model data to assess climatic conditions with fish species thermal tolerance data and potential barrier to movement data to predict future fish species distributions and/or identify species that may be vulnerable to climate projections. These species distribution data, of 13 fish species at 3 different time frames, were constructed from species distribution models containing only current, projected 2050, and projected 2099 air temperature (obtained from The Nature Conservancy Climate Wizard tool) and average United States Geological Survey hydrologic unit-8 daily discharge. Average daily discharge was calculated as the average discharge of all streamgages within...
