Livestock grazing practices are managed by private landowners and federal and state agencies across the western U.S. Increasingly, grazing strategies by these entities are incorporating conservation objectives and developing goals that include livestock production that is compatible with wildlife conservation objectives. This project evaluates the impact of conservation-oriented, rest-rotation livestock grazing and climate changes on migratory bird species associated with sagebrush habitat to better inform grazing management practices. Rest-rotation grazing management is likely to enhance important components of sagebrush, shrubland, and grassland habitat for a wide range of species, but little work has been done...

Estimating species abundance is important for land managers, especially for monitoringconservation efforts. The two main survey methods for estimating avian abundance are point counts and transects. Previous comparisons of these two methods have either been limited to a single species or have not included detection probability. During the 2012 breeding season, we compared and assessed the efficiency (precision for amount of effort) of point count time of detection (PCTD) and dependent double-observer transect (TRMO) methods based on detection probabilities and abundance estimates of five species of songbirds that use a range of habitats in a prairie system in Montana dominated by sagebrush and grassland vegetation....

The habitats and food resources required to support breeding and migrant birds dependent on North American prairie wetlands are threatened by impending climate change. The North American Prairie Pothole Region (PPR) hosts nearly 120 species of wetland-dependent birds representing 21 families. Strategic management requires knowledge of avian habitat requirements and assessment of species most vulnerable to future threats. We applied bioclimatic species distribution models (SDMs) to project range changes of 29 wetland-dependent bird species using ensemble modeling techniques, a large number of General Circulation Models (GCMs), and hydrological climate covariates. For the U.S. PPR, mean projected range change, expressed...

How did this multi-LCC initiative develop? The framework for this landscape conservation design is objective-driven across three sectors for wildlife, water quality and agriculture – ultimately doing our part to strategically maximize the value of every conservation dollar for the Mississippi River Basin and Gulf of Mexico. An intensive year-long dialogue culminated in the Memphis workshop in August 2014, setting the stage for research and development of design tools this past year. For more information, see: https://www.fws.gov/science/catalog….What is the workshop purpose? Reconvene multi-sector participants to examine the set of high impact conservation practices, web-based spatial analysis tools, and research...

The rapid expansion of pattern tile drainage (PTD) to enhance agricultural production in the Prairie Pothole Region (PPR) has the potential to negatively impact ecosystem services provided by wetlands. To better understand and assess these impacts we will develop a spatial database to provide a regional characterization of areas at risk to PTD. Spatial information in conjunction with existing data and models will be used to make preliminary projections on the effects of PTD on cosystem services such as duck production, water storage and water quality. Spatial information will be used to identify study sites that will be instrumented to quantify and model the effects of PTD systems on wetland hydrology; this information...

The collection of LiDAR data for the James River basin began in 2010. The detailed surface elevation data will be used for conservation planning, design, research, delivery, floodplain mapping and hydrologic modeling utilizing LiDAR technology. The project area includes part of the James River watershed and adjacent areas in North and South Dakota. The project encompasses 16,825 sq miles and the 2010 phase of the project acquired 8,060 sq miles of LiDAR data and subsequent terrain data. This project represents the second phase with an objective to collect the remaining 8,765 square miles of the project area.

Identifying the climatic drivers of an ecological system is a key step in assessing its vulnerability to climate change. Theclimatic dimensions to which a species or system is most sensitive – such as means or extremes – can guide methodologicaldecisions for projections of ecological impacts and vulnerabilities. However, scientific workflows for combining climateprojections with ecological models have received little explicit attention. We review Global Climate Model (GCM)performance along different dimensions of change and compare frameworks for integrating GCM output into ecologicalmodels. In systems sensitive to climatological means, it is straightforward to base ecological impact assessments onmean projected...

Oil development in the Bakken shale region has increased rapidly as a result of new technologies and strongdemand for fossil fuel. This region also supports a particularly high density and diversity of grassland bird species,which are declining across North America. We examined grassland bird response to unconventional oilextraction sites (i.e. developed with hydraulic fracturing and horizontal drilling techniques) and associatedroads in North Dakota. Our goal was to quantify the amount of habitat that was indirectly degraded by oil development,as evidenced by patterns of avoidance by birds. Grassland birds avoided areas within 150 m of roads(95% CI: 87–214 m), 267 m of single-bore well pads (95% CI: 157–378 m),...

Many waterbird species utilize a diversity of aquatic habitats; however, with increasing anthropogenic needs tomanage water regimes there is global concern over impacts to waterbird populations. The federally threatened pipingplover (Charadrius melodus; hereafter plovers) is a shorebird that breeds in three habitat types in the Prairie PotholeRegion of North Dakota, South Dakota, and Canada: riverine sandbars; reservoir shorelines; and prairie wetlands. Watersurface areas of these habitats fluctuate in response to wet–dry periods; decreasing water surface areas exposeshorelines that plovers utilize for nesting. Climate varies across the region so when other habitats are unavailable forplover nesting because of flooding,...

Conversion of grassland restored under the Conservation Reserve Program (CRP) back into croplands is occurring at a rapid rate at CRP contracts expire. A fee-market approach may be necessary to incentivize preservation of these restored grassland by assessing value to ecosystems services such as carbon sequestration.

This project will develop species distribution models (SDM) to evaluate current and future occurrence and density of wetland-dependent birds relative to several predictors, including land use patterns, wetland condition and connectivity, geomorphic setting and climate. These tools will suggest which wetland-dependent bird species appear most vulnerable to climate and land use change based on the expected extent of range change under various scenarios. Knowledge of natural history and habitat associations of species coupled with coefficients from regression models will provide insight into the potential reasons for species vulnerability. This information will be valuable in the development of management strategies.

Montana's State Wildlife Action Plan (SWAP) is a comprehensive strategy to maintain the health and diversity of wildlife within the state, including reducing the need for future listings under the Endangered Species Act. Special emphasis is given to addressing wildlife species that have received less attention in the past, including those that are not hunted or fished. All 50 states have developed SWAPs, providing a framework for planning and coordination on wildlife issues that cross state boundaries. The development and implementation of SWAPs is supported by the US Fish and Wildlife Services' State and Tribal Wildlife Grant Program.Montana's SWAP addresses a variety of wildlife and habitat management challenges,...

Temperate grasslands are among earth’s most imperiled ecosystems. In North America,steep declines of endemic songbird populations indicate that grassland loss and degradation may be approaching critical levels. Grasslands are agricultural landscapes largely (~85%) under private ownership with little formal protection status. Remaining bird populations depend on grazing lands that have not been converted to cropland. We combine regional data from a hotspot for grassland bird diversity (northeast Montana,USA; 26,500-km2) with continental data spanning the northern Great Plains (1,000,000- km2) to evaluate how land use and management influence bird distribution and abundance. Regionally, habitat used by seven grassland...

Grassland ecosystems established under the conservation reserve program (CRP) in the Prairie Pothole Region (PPR) currently provide soil conservation and wildlife habitat services. We aimed to determine if these lands also sequester soil organic carbon (SOC), as compared with neighboring croplands across multiple farms in the North Dakota PPR. We sampled soil from small plots at 17 private farms in the central North Dakota PPR, where long-term (C15 years) grasslands managed under the CRP were paired with neighboring annual croplands. Cores were collected to 100 cm and split into 0–10, 10–20, 20–30, 30–40, 40–70, and 70–100 cm soil depth layers. We hypothesized the effect of land use on soil organic carbon (SOC),...

Wetland hydroperiod, the length of time water is available in wetlands, is particularly sensitive to changes in precipitation, temperature and timing due to climate variation. Truncated hydroperiod has major implications for wetland-dependent species (e.g., waterfowl) and human water allocation. Researchers aim to link hydroperiod to current climatic variation and use this relationship to predict wetland hydroperiod across the moisture gradient from sage steppe to grasslands.

The goal of this project was to develop a landscape dynamics model to project future trends in forest area, age class distribution, and forest type (cottonwood vs. non-cottonwood) for four remnant floodplain segments on the Missouri River and, for two river segments, project effects of forest changes on abundances of forest bird species. These four river segments have not been channelized or inundated by reservoirs and thus still retain some of the natural abiotic and biotic processes of the Missouri River as it existed before human alteration. Fluvial geomorphic processes on all four, however, were significantly altered by the construction of six dams on the main stem of the river in the mid twentieth century....
