Annual populations and spatial density estimates are needed for the threatened Alaska-breeding population of Steller’s eiders (Polysticta stelleri) to assess recovery status and guide recovery actions but these quantities are poorly estimated in this rare species using traditional methods. Therefore, population size and spatial variation in density were estimated across the Arctic Coastal Plain (ACP) and Utqiagvik Triangle (Triangle) survey areas using spatio-temporal generalized additive models and compared to traditional design-based estimates. Compared to design-based estimates, model-based estimates were more precise and less variable between years. Moreover, data sets can be combined to produce common estimates,...

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;...

Conifer removal and management is a key tool for restoring sagebrush ecosystems and Greater Sage-Grouse populations, though the response of other sagebrush-obligate birds, including Pinyon Jays, to conifer management has not been well-studied. Quantifying the response of avian species to conifer management will inform conservation delivery to ensure that agencies achieve sagebrush bird and habitat objectives while minimizing impacts on Pinyon Jays in the sagebrush/pinon-juniper woodland ecotone. The results of this project will address key science needs on Pinyon Jays and directly inform more effective conifer management throughout the eastern Great Basin. Without these data, we will be unable to provide science-based...

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...

Insect pollinators-particularly native bees-are critically important in the maintenance of terrestrial plant and animal communities, yet our understanding of how contemporary threats influence this group and the pollination services they provide is virtually unstudied with the sagebrush biome. Our investigation will quantify how bee communities respond to widespread threats to sagebrush-wildfire and invasive annual grasses-and provide foundational knowledge needed for undertaking informed management decisions to improve the resilience of the biome.

Grassland loss to woody encroachment is widespread and ongoing. Mechanical removal of Eastern Red Cedar (ERC) is the most cost-shared practice to address this threat. Cost-share is provided based on acres with different levels of infestation. Delineation of the different levels of infestation is time consuming butrequired to ensure the appropriate amount of cost-share is provided and contractors are not over/under compensated. The Rangeland Brush Estimation Toolbox(RaBET) is geospatial tool that can accurately automate this process. Unfortunately,wet-meadows and other wetland features cause the tool to overestimate woody cover. This project will provide funds to finish the National Wetlands Inventory (NWI). This...

Communicating the value of keeping existing grass as grass is a high priority of the Northern Great Plains Joint Venture partnership to ensure rangeland retention activities receive recognition as an important strategy for implementing strategic grasslands conservation. This is a pilot effort to assess socio-economic factors associated with avoided loss of grasslands (i.e., what is the value to individual landowners, communities, and to society of voluntarily retaining working grasslands?). This assessment may include the value of ecosystem services but also financial impacts on communities and municipalities, food supply chains, public services, schools, etc.; it is anticipated to be informed by an expert panel....
Strategic conservation of at-risk species is a priority for the Northeast Region of the U. S. Fish and Wildlife Service (Service). We define at-risk species as those that are at risk of becoming threatened or endangered, that are in decline throughout their range, and for which we can make a positive change in the near term if we act collectively and strategically. Across the continent, freshwater mussels have experienced drastic declines. Over 74 % of the 306 species found in North America are in some state of imperilment, with 93 species federally listed as endangered or threatened. Many species are facing critical impairment where their continued existence depends on rapid, targeted intervention, while other...

The Conservation Efforts Database (CED) in a web-based monitoring and reporting tool that captures data about the conservation, restoration, and recovery actions for the imperiled sagebrush ecosystemand sage-grouse. Funding support from FWS (Science Applications and Nevada Ecological Services) have allowed the CED Team to develop a module for recording data about conservation actions, habitat condition, demography, and genetic information for Lahontan Cutthroat Trout and we propose to expand that effort to include aquatic systems in Legacy Region 6. We propose to use funding to engage with stakeholders to scope the information gaps and tool needs to record and monitor conservation actions and information focused...

We will apply indices of sagebrush ecological integrity, developed by WAFWA, to hierarchical population models of sage-grouse population rates of change over multiple decades to facilitate comprehensive understanding of the links between sagebrush ecosystem health and sagebrush obligate species from the lens of the Conservation Design Strategy. This research will investigate application of core area habitat concepts as it relates to sage-grouse population performance to manage lands within the sagebrush biome. The analysis framework and science deliverables developed from this study can be used as a basis to investigate the population performance of additional species of concern, beyond sage-grouse, in relation...

This funding will be used to hire 1 GS 9/11 staff member to work directly with local governments (Soil & Water Conservation Districts) to enroll landowners in priority habitats in existing Candidate Conservation Agreements with Assurances (CCAAs) and in Candidate Conservation Agreements (CCAs) on their adjacent BLM allotments. Once enrolled, state and other federal funding sources are available to support sagebrush habitat enhancement projects that address invasive species, fire, juniper encroachment and other threats. The additional capacity is expected to result in an additional +100 landowners enrollments.

Grassland birds have declined more rapidly than any other group of land birds in North America in the last 50 years, with populations of Spragues Pipit, Chestnut-collared and Thick-billed Longspur, and Bairds Sparrow having declined 65-94% during this period. Developing strategic conservation plans for grassland birds requires an understanding of their individual population ecology, along with their community dynamics amongst species. Few studies have focused on understanding how adult density during the breeding season relates to nesting performance (e.g., nest density and nest success) and how abiotic and biotic factors influence these individual demographics. This proposed work complements concurrent studies...
The Delaware River clubtail (Gomphurus septima delawarensis) is an endemic dragonfly subspecies found in the Delaware River watershed. Due to significant data gaps regarding its taxonomy, distribution, habitat associations, and response to key threats, it is considered a Science Needs species by the Science Applications program in the Northeast. This pilot study is focused on the known historic locations for the subspecies in New York and intends to field-test survey methodologies for assessing its distribution within the Delaware watershed. We will collect all Gomphidae exuviae (shed larval skins) encountered during timed searches at 11 historical locations across New York. These surveys will be repeated at these...
