Advancement in Geographical Information System (GIS) data development, management, and analysis has allowed conservation practitioners to apply ecological theory into conservation delivery at broad landscape scales. This project demonstrated that process with the creation of Decision Support Tools (DST) to guide on-the-ground habitat delivery to those areas on the landscape that, if managed, will provide the greatest biological return for the conservation dollar invested. This project focused on the habitat needs of Sandhill cranes and waterfowl, as a guild, during spring migration. Understanding the species habitat relationships for these priority species/guild will allow the conservation community to more effectively...

Natural resource management requires decision making in the face of uncertain future conditions. Climate change has been identified by our partnership as a high-priority threat to grasslands and all of our priority habitats, affecting water availability, species composition, species interactions, phenology, and other factors. Climate change is understood to be a factor in nearly all natural resource issues, but managers find it difficult to plan for climate change because of high levels of uncertainty. Multiple Global Climate Models (GCMs), CO2 emission scenarios, downscaling methods, and combinations of these compound our uncertainty. Natural resource managers need a simple way to evaluate climate-driven changes...

While we assessed the vulnerability of a number of different wildlife and plant species to climate change, none of those species exhibited high vulnerability to changes projected for the region and there was limited differentiation in vulnerability between the individual species. Given this shared level of vulnerability to climate change, we chose to focus our adaptation planning on grassland birds as they represent a large group with a diversity of habitat needs. These birds are obligate grassland wildlife species which have great potential to act as indicators for habitat quality since different species have distinct habitat structure needs. Participants in the adaptation planning workshop agreed that if the GP...
The potential implications of climate change to fishes in Great Plains rivers and streams could range from drastic shifts in distribution to extirpation. Many lotic systems in the Great Plains are not well suited for direct escape routes for fish to move to more suitable habitats at other latitudes due to the west-east direction of flows rather than north-south. Therefore, we might expect additional climate related stress on fish communities in the Great Plains compared to other regions of North America. Therefore, we will 1) simulate potential water temperature and flow changes within the Great Plains based on extant regional climate models, 2) assess stream connectivity to potential refugia, 3) develop a database...

Building upon the successful efforts of SARP, Texas Parks and Wildlife Department (TPWD), and other federal, state, and local partners to establish and implement NFCAs in the Llano River watershed, TX and Chipola River watershed, FL (Birdsong et al., 2015, Garrett et al. 2015), we will coordinate a series of watershed-based conservation planning workshops focused on eight priority river systems in the Great Plains (i.e., the White River, Platte River, Arkansas-Kansas Rivers, Canadian River, Deep Fork River, Red River, Brazos River, and Colorado River). We will utilize conservation assessments and conservation planning tools recently developed by Labay and Henderickson (2014; http://repositories.lib.utexas.edu/handle/2152/27744)...

This ranking criterion was developed to identify those pits that most negatively impact watershed integrity of publically owned and Wetland Reserve Program (WRP) playa wetlands. Currently, the U.S. Fish and Wildlife Service (USFWS) manages 59 Waterfowl Production Areas (WPAs) while the Nebraska Game and Parks Commission oversees 35 Wildlife Management Areas (WMAs). These wetlands flood as a result of precipitation or snow melt. With the transition to pivot irrigation, a large number of irrigation reuse pits have been abandoned over recent years. Although not being used for irrigation, these pits continue to fill with water from precipitation events shortstopping water that could have reached the neighboring...

Habitat loss and fragmentation are widely recognized as among the most important threats to global biodiversity. New analytical approaches are providing an improved ability to predict the effects of landscape change on population connectivity at vast spatial extents. This paper presents an analysis of population connectivity for three species of conservation concern [swift fox (Vulpes velox); lesser prairie-chicken (Tympanuchus pallidicinctus); massasuaga (Sistrurus catenatus)] across the American Great Plains region. We used factorial least-cost path and resistant kernel analyses to predict effects of landscape conditions on corridor network connectivity. Our predictions of population connectivity provide testable...

Priority and use segments for waterfowl (ducks and geese). Segments designated as use areas were utilized during annual spring surveys 2014-2016. The reduced model for ducks indicated a relationship between total area of grass habitats, open water, crops, and wetlands, as well as mean distance to roads.

Several final products have been submitted to U.S. Fish and Wildlife Service in addition to this final report: the Master’s thesis (Mueller 2013) “Effects of temperature, salinity, and suspended solids on the early life history stages of Arkansas River shiner”; and the publication “Sampling efficiency of the Moore egg collector” (available at DOI:10.1080/02755947.2012.741557) by Worthington et al. (2013). These products present completed results for portions of the two major objectives and will not be repeated here. Results from the remaining portions are presented in this report: 1) determine the landscape-level effects on the probability of Arkansas River shiner presence, and 2) assess egg transport related to...

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...

The black‐tailed prairie dog (Cynomys ludovicianus) is considered an indicator species for the short grass prairie of North America; however, this species currently occupies an estimated 2% of its original distribution. Persistent and pervasive poisoning, and sylvatic plague have fragmented the remaining populations. It is not well understood how these population fragments are connected in a heterogeneous landscape of land use practices and land cover types, but quantifying population isolation and individual measures of dispersal across the landscape are essential to predicting both the vulnerability of extinction due to stochastic processes and the probability of disease emergence. To better understand how land...

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.

Within the five states of its range (Texas, Oklahoma, Kansas, New Mexico, and Colorado), the lesser prairie-chicken (Tympanuchus pallidicinctus, LEPC) remains present on sand sagebrush (Artemesia filifolia), mixed- and short- grass prairies of western Kansas and eastern Colorado, through portions of northwest Oklahoma, the northeast Texas panhandle, and into the shinnery oak (Quercus havardii) and sand sagebrush habitat of eastern New Mexico and western Texas. Agencies in these states monitor LEPC breeding populations annually within the known occupied range of the species, however, monitoring efforts have differed markedly among agencies and inferences have been made about populations using a variety of methods....

We found few reports in the literature containing useful data on the nesting phenology of lesser prairie-chickens; therefore, managers must rely on short-term observations and measurements of parameters that provide some predictive insight into climate impacts on nesting ecology. Our field studies showed that prairie-chickens on nests were able to maintain relatively consistent average nest temperature of 31 °C and nest humidities of 56.8 percent whereas average external temperatures (20.3–35.0 °C) and humidities (35.2– 74.9 percent) varied widely throughout the 24 hour (hr) cycle. Grazing and herbicide treatments within our experimental areas were designed to be less intensive than in common practice. We determined...
