The emerging multi-LCC Ecological Places in Cities Network integrates the ecological and urban communities to guide and promote conservation practices, such as those across the monarch flyway. The ETPBR LCC is working with a number of other Service programs and external partners to build capacity for the development and implementation of a framework that can be tailored to individual cities of various sizes to evaluate their unique situations and design an urban monarch conservation strategy that optimizes the potential contributions of their urban area. Specifically, this project will continue to lay the groundwork for design principles to guide the development, testing and deployment of future urban conservation...

This dataset contains locations acquired from GPS-tagged Brown Pelicans in the South Atlantic Bight. Locations correspond to the movements of pelicans tracked during the autumn migratory period (post-breed to the following spring, with length of deployment varying individually) from 2017-2020. Additional metrics include intrinsic and extrinsic variables both measured and acquired which may influence migration.

Capacity to prioritize barrier removals in the Great Lakes basin is currently limited by lack of data on the passability of road crossings and dams for both unwanted invasive species and desirable native migratory fishes. Building upon our initial barrier inventory, this project has two key elements. First, we are testing whether our landscape statistical models accurately predict the upstream limits of fish migrations along the Wisconsin coast of Lake Michigan. This involves intensive field work to determine the actual upstream limits of suckers, pike, and steelhead during the spring migration. Second, we are collecting systematic data on the size and condition of dams throughout the Lake Michigan basin. These...

Each year, plants and animals undergo certain life cycle events, such as breeding or flowering. These phenological events are linked to weather and climate, and as temperature and precipitation patterns have changed, some spring events are occurring earlier. These changes in plant phenology can have cascading effects on wildlife such as elk, moose, and mule deer, which depend on plants for food. It’s thought that the quality of forage available in the spring could play a critical role for these big game species, which need to replenish energy depleted during the winter, in order to survive and successfully reproduce. Climate change will alter plant phenology, which in turn is likely to effect when, where, and for...

Understanding how routing modifications influence survival of juvenile salmon is complex because reach-specific survival and routing at key river junctions in the North Delta each have a different relationship with river flow. Therefore, to facilitate understanding of how routing modifications at key river junctions influence through-Delta survival, we developed this spreadsheet model to allow managers to explore the potential effects of modifying routing. The purpose is to provide a screening tool that allows managers to quickly run many different scenarios to understand how both routing and route-specific survival interact to affect overall survival through the Delta. This tool may be useful in narrowing the range...

Waterfowl are ecologically, culturally, and economically important and their annual and long-term distributions in North America can substantially impact ecological relationships and have economic impacts. In Mississippi, Arkansas and Louisiana alone, recent annual sales of Federal Duck Stamps equal $2.4 million. An intensive study in Mississippi estimated the annual total economic impact of waterfowl hunting in that state was $86.8 million. North American waterfowl number in the millions, use a diversity of aquatic and terrestrial foraging niches, and can feed at rates capable of depleting local food resources. In recent years, waterfowl appear to be wintering at more northern latitudes. Sustained northern...

These data, which support a USGS authored manuscript, describe how active and previous previous infection with avian influenza impacts the movement ecology of several wild waterfowl species that overwinter in California. Results varied by species and demonstrate that the relationships between avian influenza infection and wild bird movements are context- and species-dependent.

Plants and animals undergo certain recurring life-cycle events, such as migrations between summer and winter habitats or the annual blooming of plants. Known as phenology, the timing of these events is very sensitive to changes in climate (and changes in one species’ phenology can impact entire food webs and ecosystems). Shifts in phenology have been described as a “fingerprint” of the temporal and spatial responses of wildlife to climate change impacts. Thus, phenology provides one of the strongest indicators of the adaptive capacity of organisms (or the ability of organisms to cope with future environmental conditions). In this study, researchers are exploring how the timing and occurrence of a number of highly...

The annual distributions of waterfowl during autumn-winter can influence ecological, environmental, cultural, and economic relationships. We used previously developed Weather Severity Indices (WSI) that explained migration by dabbling ducks in eastern North America and weather data from the North American Regional Reanalysis to develop an open-access internet-based tool (i.e, WSI app) to visualize and query WSI data. We used data generated by the WSI app to determine if the weather known to elicit southerly migration by dabbling ducks had changed, October – April 1979 – 2014.We detected that the amount of area in the Mississippi and Atlantic Flyways with weather severe enough to cause southerly migration decreased...

Improving the quality of habitat for western big-game species, such as elk and mule deer, was identified as a priority by the Department of the Interior in 2018. Maintaining healthy herds not only supports the ecosystems where these species are found, but also the hunting and wildlife watching communities. For example, in Wyoming, big game hunting contributed over $300 million to the state’s economy in 2015. Yet as climate conditions change, the quantity, quality, and timing of vegetation available to mule deer, elk, and other ungulates, known as forage, could shift. It’s possible that these changes could have cascading impacts on the behavior and population sizes of many species. A key strategy used by managers...

Mapping of barriers and statistical prediction of their passability is now fairly complete in the Great Lakes basin, yet field assessments of barrier characteristics and passability to migratory fishes are spotty. We will use the Lake Michigan basin as a pilot area for comprehensive field assessment of dam condition, dimensions, and passage technologies. These characteristics will be incorporated into our barrier database, enabling improved estimates of removal costs, watershed cumulative passability, and infrastructure maintenance challenges. In parallel, we will conduct field assessments of passability to spring migrations of Great Lakes fishes in 15 Wisconsin watersheds. Recording the upstream limits of migrations...
