Biodiversity in stream networks is threatened globally by interactions between habitat fragmentation and altered hydrologic regimes. In the Great Plains of North America, stream networks are fragmented by 19,000 anthropogenic barriers, and flow regimes are altered by surface water retention and groundwater extraction. We documented the distribution of anthropogenic barriers and dry stream segments in five basins covering the central Great Plains to assess effects of broad-scale environmental change on stream fish community structure and distribution of reproductive guilds. We used an information theoretic approach to rank competing models in which fragmentation, discharge magnitude, and percentage of time streams...

Potamodromous migrations, those that occur entirely in fresh waters, are made by a variety of minnows (Family Cyprinidae) in, and between, freshwater habitats around the world. These migrations most commonly are undertaken for purposes of breeding, feeding, or occupying specific habitats or refugia. There is a growing body of evidence that potamodromous migrations are undertaken by a number of cyprinids native to larger streams and rivers of the Great Plains region of central USA. Cross et al. (1985) observed that populations of Arkansas River shiner disappeared from large tributaries to the Arkansas River, in Kansas, as a result of dam construction and water withdrawal. They speculated that populations in these...

The range-wide plan (RWP) has been developed in response to concerns about lesser prairie-chicken (LPC) habitat threats which may be impacting LPC populations, and the proposed listing under the Endangered Species Act (ESA). Along with the existing conservation efforts already being implemented, as described in the RWP, the supporting WAFWA Conservation Agreement (WCA) represents another mechanism to implement conservation to benefit LPC. The WCP represents an opportunity to enroll participants who agree to avoid, minimize and mitigate actions which may be detrimental to LPC. Landowners may enroll properties to be managed for the benefit of LPC. Properties may generate credits for mitigation. When complete avoidance...

The Arkansas River Shiner (ARS), Notropis girardi, is a federally threatened minnow that now occurs natively in modest numbers only in the South Canadian River, following decades of range contraction and population losses. The remaining populations are at increasing risk as global change is expected to impact the upper and middle South Canadian River with a rise in temperature as much as 4-6 F and a decrease in precipitation from 10 to 35 % in this century. The primary objective of this project was to evaluate potential effects of habitat and environmental change on Arkansas River shiners by examination of habitat use and availability at several spatial scales using both historical and recently-collected data from...

Species populations are in a state of flux due to the cumulative and interacting impacts of climate change and human stressors across landscapes. Invasive spread, pathogen outbreaks, land-use activities, and especially climate disruption and its associated impacts—severe drought (see Figure 3 or the GPLCC), reduced stream flow, increased wildfire frequency, extended growing season, and extreme weather events—are increasing, and in some cases accelerating. These impacts are outpacing management and conservation responses intended to support trust species and their critical habitats. Our common goal is to craft successful adaptation strategies in the face of these multiple, interacting drivers of environmental change....

Genetic, demographic, and environmental processes affect natural populations synergistically, and understanding their interplay is crucial for the conservation of biodiversity. Stream fishes in metapopulations are particularly sensitive to habitat fragmentation because persistence depends on dispersal and colonization of new habitat but dispersal is constrained to stream networks. Great Plains streams are increasingly fragmented by water diversion and climate change, threatening connectivity of fish populations in this ecosystem. We used seven microsatellite loci to describe population and landscape genetic patterns across 614 individuals from 12 remaining populations of Arkansas darter ( Etheostoma cragini) in...

These data represent a potential future condition of large block grasslands if CRP lands expire and the land-use reverts back to cropland. Data layers for 2022 and 2027 were calculated by reclassing CRP lands scheduled to expire prior to these years to cropland and recalculating the large block grasslands layer as described above.

These data represent the long term average (27 year) amount of duck energy days available in wetlands. Data were produced as part of the PLJV waterfowl implementation plan. We used data from recently completed studies investigating food resource availability in a variety of wetland types in the PLJV. Beheny (2017) completed a study of food energy availability in five different wetland types in northeastern Colorado. Clark (2016) investigated food resource availability in stock ponds in BCR 19 in Texas. For the wetland DED values reported in both studies, we assumed these values were appropriate for use across the whole Joint Venture region. We used Landsat 5 data to determine wetness frequency over 27 years (1985-2012)...

To estimate wetland DEDs available in the future (2040) we used data from Bartuszevige et al. 2016 which estimates changes in playa functionality as a result of sedimentation, potential wind development, and tillage. Playas estimated to be impacted by these drivers were eliminated from the wetland landcover map and the process of calculating duck energy days described above was repeated.

Leaders within the Kansas Department of Wildlife, Parks and Tourism and the Nebraska Game and Parks Commission recognized the need for current vegetation datasets and maps to facilitate conservation planning and management. Prior to the initiation of this project, Ecological Mapping System (EMS) datasets had been completed by the Missouri Resource Assessment Partnership (MoRAP) for Texas and Oklahoma. The U.S. Fish and Wildlife Service facilitated meetings among states that highlighted the Texas and Oklahoma datasets. This led state leaders in Kansas and Nebraska to initiate the current project, with the aims of (1) producing the highest quality digital and map datasets possible, and (2) leveraging funds from each...

Across the western Great Plains of North America, groundwater pumping for irrigated agriculture has depleted regional aquifers that sustain stream flow for native fishes. Although declines in Great Plains stream discharge owing to groundwater pumping are widely documented, spatial and temporal patterns in stream intermittency across this broad landscape have yet to be quantified. Successful management of native Great Plains stream fishes into the future will require an explicit understanding of the distribution and abundance of habitats, as well as the connections among those habitats across the region. The goal of this study was to provide critical information and decision-support tools to enhance conservation...

The influence of recent climate change on the world’s biota has manifested broadly, resulting in latitudinal range shifts, advancing dates of arrival of migrants and onset of breeding, and altered community relationships. Climate change elevates conservation concerns worldwide because it will likely exacerbate a broad range of identified threats to animal populations. In the past few decades, grassland birds have declined faster than other North American avifauna, largely due to habitat threats such as the intensification of agriculture. We examine the effects of local climatic variations on the breeding performance of a bird endemic to the shortgrass prairie, the Lark Bunting (Calamospiza melanocorys) and discuss...

Playa wetlands on the west-central Great Plains of North America are vulnerable to sediment infilling from upland agriculture, putting at risk several important ecosystem services as well as essential habitats and food resources of diverse wetland-dependent biota. Climate predictions for this semi-arid area indicate reduced precipitation which may alter rates of erosion, runoff, and sedimentation of playas. We forecasted erosion rates, sediment depths, and resultant playa wetland depths across the west-central Great Plains and examined the relative roles of land use context and projected changes in precipitation in the sedimentation process. We estimated erosion with the Revised Universal Soil Loss Equation (RUSLE)...
These are vector (polygon) inventories of woodland features that were part of a Rainwater Basin land cover mapping effort. These features were digitized using 2010 USDA National Agricultural Imagery Program (NAIP). These features created in 2011-2012 and were incorporated in to RWBJV Nebraska land covers starting in version 10.
The Central Platte River Image Library is an extensive dataset of historic 1860's surveys by the Government Land Office and aerial photographs from 1938-2012. All datasets are either public domain property of the U.S. Government or published by the Rainwater Basin Joint Venture (RWBJV) with permission from the respective owner (specifically the Platte River Recovery Implementation Program or Central Platte Natural Resources District). The Central Platte River region of Nebraska extends from approximately Jeffery Reservoir (Western Extent) to Columbus (Eastern Extent). The library was completed May 2014 - Sept 2016 by the Rainwater Basin Joint Venture.
