Cottonwood forests are in decline becasue of losses from land use conversion and reduced regeneration from river regulation. Projecting lon-term implications of current trends and policies, or alterations of these, will help to identify the importance and scale of restoration activities needed to offset losses. This project developed a landscape dynamic model to project future (eig. 25, 50, 100 year) trends in cottonwood forst area and age distribution for four remnant floodplain reches on the Missouri River, based on recent rates (or alternative scenarios) of land use change, cottonwood recruitment, and succession. For two reaches, these changes are used to project the effects onabundances of selected songbird...

Habitat loss is one of the key factors contributing to loss of wildlife, but ultimately it comes down to decisions made at he private landowner. Economin pressures from comodity prices probably heavily wieght in decisions. However, understanding how a private landowner responds to economic incentives and pressures may identify strategies to reduce habitat loss in the plains and prairie pothole region. Also, farmers & ranchers generally have more thn an econominc interest in their lands with strong social and cultura ties. The aging trend inteh agricultrual industry is another factor contributing to decisions about land, foten with farm/rances being split among surviving relatives who may not continue to...

Rapid expansion of cropland threatens grassland ecosystems across western North America and broad-scaleplanning can be a catalyst motivating individuals and agencies to accelerate conservation. Sprague’s Pipit(Anthus spragueii) is an imperiled grassland songbird whose population has been declining rapidly in recent decades.Here, we present a strategic framework for conservation of pipits and their habitat in the northern GreatPlains.We modeled pipit distribution across its million-km2 breeding range in Canada and the U.S.We describefactors shaping distribution, delineate population cores and assess vulnerability to future grassland losses. Pipitsselected landscapes with a high proportion of continuous grassland...

This project seeks to develop a tool that strategically identifies priority areas for land protection. This is a pilot study to assess the extent of taxa that contain adequate genetic sampling within the south Atlantic ecoregion for characterization of intraspecific genetic variation. We seek to use genetic data from multiple taxa coupled with GIS data to provide a genetic landscape from which geographic patterns of intraspecific genetic diversity will be inferred. Joint analyses of the resulting genetic landscapes will be used to identify geographic areas where multiple species show atypical patterns of interpopulation divergence or intrapopulation diversity (i.e., a hotspot of high biological value). We will then...

The South Atlantic Conservation Blueprint is a living spatial plan to conserve natural and cultural resources for future generations. It identifies shared conservation priorities across the South Atlantic region. The first Blueprint, Version 1.0, was released in March 2014. Blueprint 1.0 was based on a combination of expert input and partner plans and used a spatial scale of HUC-12 subwatersheds in the terrestrial environment and outer continental shelf lease blocks in the marine environment. More than 300 people from 85 organizations were actively involved in developing this version of the Blueprint.

Within the time frame of the longevity of tree species, climate change will change faster than the ability of natural tree migration. Migration lags may result in reduced productivity and reduced diversity in forests under current management and climate change. We evaluated the efficacy of planting climate-suitable tree species (CSP), those tree species with current or historic distributions immediately south of a focal landscape, to maintain or increase aboveground biomass, productivity, and species and functional diversity. We modeled forest change with the LANDIS-II forest simulation model for 100 years (2000–2100) at a 2-ha cell resolution and five-year time steps within two landscapes in the Great Lakes region...
* The PFLCC, in conjunction with GeoAdaptive (GA) and Geodesign Technologies (GDT), completed a set of comprehensive conservation planning scenarios for the state of Florida in 2014. The scenarios considered variations in climate change, urban growth, conservation funding, and conservation strategy and were designed using a stakeholder-based process involving both the science advisory board and steering committee of the PFLCC. This represents the first statewide effort to assess likely alternative futures for conservation considering an array of financial, biological, climatological, and urban growth pattern conditions. Land use and land tenure changes were simulated to systematically allocate potential future conservation...

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...

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.
This project evaluates the effects of global climate change and sea level rise on estuarine intertidal habitat in the San Francisco Bay and the Pacific Flyway migratory waterbirds that rely on this habitat. Phase 2 of this project is a continuation of work to evaluate the effects of global climate change and sea level rise (SLR) on intertidal shoals in the San Francisco Bay Estuary and the migratory waterbirds that rely on this critically important resource in the Pacific Flyway. The primary objectives are to: 1) use downscaled global climate change models to translate SLR and climate scenarios into habitat quantity predictions through Delft3D and Dflow-FM (unstructured grid) geomorphic modeling; 2) model the response...
This project integrates fire risk models, species distribution models (SDMs) and population models with scenarios of future climate and land cover to project how the effects of climate-induced changes to species distributions and land use change will impact threatened species in fire-prone ecosystems. This project also identifies and prioritizes potential management responses to climate change (e.g. assisted colonization, fire management, land protection, dispersal corridors). Anticipated products include: 1) maps (digital and hard copy) of habitat suitability under current and future climate change, current and future projected urban growth and combinations of climate change and future projected urban growth, under...

This project used species distribution modeling, population genetics, and geospatial analysis of historical vs. modern vertebrate populations to identify climate change refugia and population connectivity across the Sierra Nevada. It is hypothesized that climate change refugia will increase persistence and stability of populations and, as a result, maintain higher genetic diversity. This work helps managers assess the need to include connectivity and refugia in climate change adaptation strategies. Results help Sierra Nevada land managers allocate limited resources, aid future scenario assessment at landscape scales, and develop a performance measure for assessing resilience.

The focus of the first Midwest Urban Conservation Workshop was to understand the challenges stakeholders are facing, define the needs for collaboration and best management practices, establish a platform for conversation focusing on learning from each other and creating an opportunity for collaboration on new initiatives through a collective impact. The workshop was framed around the idea of making a collective impact, as what happens upstream directly affects what happens downstream. Over 40 participants included scientists, urban planners, and state, federal, private and nonprofit organizations with interests in creating a network of professionals interested in the value of our waterways. We envision a world where...
