This project used species distribution modeling to assess the risk to habitat change under various climate change scenarios for rare plants. To predict the response of rare plant species to climate change, the project modeled the current distribution of the species using climate and environmental data (e.g., soils, disturbance, land-use), use these models to predict the species distribution given climate change, calculate current and future range size, calculate the amount of overlap of predicted future distribution with current distribution, and assess where barriers and protected areas are located with reference to the change in species distribution. Given the results of the distribution modeling, each species...

Rate of global biodiversity loss increased significantly during the 20th century associated with human environmental alterations. Specifically, mismanagement of freshwater resources contributed to historical and contemporary loss of stream-dwelling fish diversity and will likely play a role in determining the persistence of species in the future. We present a mechanistic pathway by which human alteration of streams has caused the decline of a unique reproductive guild of Great Plains stream-dwelling fishes, and suggest how future climate change might exacerbate these declines. Stream fragmentation related to impoundments, diversion dams and stream dewatering are consequences of increasing demand for freshwater resources...

We propose to use long-term fish-population data from a relict reach of the Pecos River, New Mexico to assess population dynamics of imperiled prairie-river minnows, including Arkansas River shiner. Development of viable management strategies requires basic understanding of population ecology. Rigorous, quantitative ecological methods can be used to analyze continuous, long-term demographic data, but such data are rarely available for imperiled, non-game fishes. Data available for the Pecos River provide a unique opportunity to apply quantitative methods to prairie-river minnow conservation and management. Analyses proposed here would determine (1) whether population regulation is density dependent or flow-regime...

The Department of the Interior and the U.S. Geological Survey have made it a priority to train the next generation of scientists and resource managers. The Climate Adaptation Science Centers (CASCs) and consortium institutions are working to contribute to this initiative by building and supporting a network of students across the country who are interested in the climate sciences and climate adaptation. The purpose of this project was to support the development of a national early career communication platform to facilitate and increase information sharing and networking across the CASCs and consortium institutions. This was accomplished by working with the Early Career Climate Forum (ECCF), a CASC-supported science...

In the northern Gulf of Mexico, mangrove forests have been expanding their northern range limits in parts of Texas, Louisiana, and north Florida since 1989. In response to warming winter temperatures, mangroves, which are dominant in warmer climates, are expected to continue migrating northward at the expense of salt marshes, which fare better in cooler climates. The ecological implications and timing of mangrove expansion is not well understood, and coastal wetland managers need information and tools that will enable them to identify and forecast the ecological impacts of this shift from salt marsh to mangrove-dominated coastal ecosystems. To address this need, researchers will host workshops and leverage existing...

Appropriate ecological indicators of climate change can be used to measure concurrent changes in ecological systems, inform management decisions, and potentially to project the consequences of climate change. However, many of the available indicators for North American birds do not account for imperfect observation. We proposed to use correlated-detection occupancy models to develop indicators from the North American Breeding Bird Survey data. The indicators were used to test hypotheses regarding changes in range and distribution of breeding birds. The results will support the Northeast Climate Science Center’s Science Agenda, including the science priority: researching ecological vulnerability and species response...

There is growing evidence that headwater stream ecosystems are especially vulnerable to changing climate and land use, but managers are challenged by the need to address these threats at a landscape scale, often through coordination with multiple management agencies and landowners. This project sought to provide an example of cooperative landscape decision-making by addressing the conservation of headwater stream ecosystems in the face of climate change at the watershed scale. Predictive models were built for critical resources to examine the effects of the potential alternative actions on the objectives, taking account of climate effects and examining whether there are key uncertainties that impede decision making....

The distribution and abundance of cheatgrass, an invasive annual grass native to Eurasia, has increased substantially across the Intermountain West, including the Great Basin. Cheatgrass is highly flammable, and as it has expanded, the extent and frequency of fire in the Great Basin has increased by as much as 200%. These changes in fire regimes are associated with loss of the native sagebrush, grasses, and herbaceous flowering plants that provide habitat for many native animals, including Greater Sage-Grouse. Changes in vegetation and fire management have been suggested with the intent of conserving Greater Sage-Grouse. However, the potential responses of other sensitive-status birds to these changes in management...

Covering 120 million acres across 14 western states and 3 Canadian provinces, sagebrush provides critical habitat for species such as pronghorn, mule deer, and sage-grouse – a species of conservation concern. The future of these and other species is closely tied to the future of sagebrush. Yet this important ecosystem has already been affected by fire, invasive species, land use conversion, and now, climate change. In the western U.S., temperatures are rising and precipitation patterns are changing. However, there is currently a limited ability to anticipate the impacts of climate change on sagebrush. Current methods suffer from a range of weakness that limits the reliability of results. In fact, the current uncertainty...

Observing and counting bats is extremely difficult. Bats hide during the day, fly in darkness, and most species in the United States (US) become inactive and inaccessible in cryptic hibernation sites for 7-8 months each year. More than 40 different species of bats occur year-round in the US, yet reasonable population estimates exist for very few. Populations of US bats face new and unprecedented threats from white-nose syndrome (WNS) and industrial wind turbines. Like WNS, wind energy development might adversely affect entire populations of bats. Species of bats dying at wind turbines in the greatest numbers rank among the most cryptic, elusive, and poorly understood. Hoary bats (Lasiurus cinereus) compose approximately...

Invasive annual grasses are a primary, severe, and challenging threat to habitat conservation and restoration for sage-dependent wildlife across federal, state and private lands. Successful management solutions for sagebrush rangelands are likely to be multiphasic, involving some sequence of interventions such as herbicides, seeding of competitive natives that also create habitat, and temporarily altering land use, in an adaptive-management approach. The proposed work tests different herbicides and options for applying them with different seeding and land uses, across a gradient of climate and soils in Interior Regions 5 and 7.This research will examine the efficacy of management options for controlling cheatgrass...

Conifer encroachment is one of the most significant threats to sagebrush habitats and the species that rely on them. Removal of encroaching conifers is beneficial for Greater Sage-Grouse, but impacts on other sagebrush-obligate species are not well understood. This project aims to quantify the impact of conifer removal on sagebrush songbird abundance and reproductive success. Work has been initiated through a previously-supported (by IR5/7 SA) Cooperative Fish and Wildlife Research Unit project across six conifer-removal and six conifer-remaining (control) plots of ca. 55 ha each. Initial results suggest that conifer removal benefits both abundance and nesting success of sagebrush-obligate species (Brewers Sparrows...

The Wind River Reservation in Wyoming contains over 2 million acres of the best and most diverse and intact habitats in the contiguous US. It is home to the Eastern Shoshone and Northern Arapaho Tribes. In collaboration with Tribal Fish and Game, the USFWS Lander Fish and Wildlife Conservation Office and the USGS Wyoming Cooperative Research Unit, partners have been conducting an investigation of the migration patterns of 113 GPS-collared mule deer that began in 2018. As part of our SA diversity and inclusion efforts with a $60,500 investment, this project will extend the ongoing work and engage various segments of the tribal community in the research as a means to further understanding of fish and wildlife management...

To better inform conservation efforts targeted at reversing grassland bird declines and ensure self-sustaining populations of at-risk species such as the lesser prairie-chicken (Tympanuchus pallidicinctus), a better understanding of broad-scale habitat availability for grassland birds is needed. his project will evaluate the utility of NDVI and phenology-based metrics in estimating lesser prairie-chicken reproductive habitat quality remotely over broad spatial scales.1. Evaluate the influence of grazing, fire, and precipitation on NDVI-related metrics in the Central and Southern Great Plains.2. Identify NDVI-related metrics that best distinguish lesser prairie-chicken reproductive habitat from non-habitat. 3. Relate...

The US Prairie Pothole Region (PPR) has experienced some of the highest rates of grassland loss in North America over a time that coincides with dramatic declines in grassland songbird populations yet increasing abundance of most grassland-nesting duck species except for northern pintail. To provide more insight into this contradiction, we propose to capitalize on long-term databases to evaluate how a key population driver nest survival for North American ducks has responded to system changes in the region including landscape and climatic factors. Outcomes of these analyses will contribute to testing primary conservation planning assumptions for the PPJV a vital component of the PPJV Strategic Habitat Conservation...

Using a solutions-oriented, multi-agency collaboration, we propose to pilot a large-scale assessment of an alternative (herding, electric- and virtual-fence) grazing strategy designed to mimic pre-colonial grazing patterns by bison, to ascertain their value for local- and regional-scale assemblages ofsagebrush- and grassland-associated birds in Montana. A fundamental goal of most wildlife-based grazing programs is to foster a mosaic of patches that represent the broadest possible spectrum of habitat types that benefits different sagebrush- and grassland-associated birds in different parts of the landscape (for example, western meadowlarks, vesper sparrows, and thick-billed longspur in open, heavily grazed areas;...
