California’s Central Valley is a nexus for water resources in the state, draining the Sacramento and San Joaquin River watersheds. Urban centers, agricultural operations, and the environment all compete for limited water, and demand is expected to only increase as the population grows and agriculture intensifies. At the same time, the water supply is projected to decrease as temperatures rise, precipitation patterns change, and the frequency of extreme droughts increases. The Central Valley also provides critical wetland habitats to migratory waterbirds, and wetland managers require information on how to best use water resources to support wildlife objectives, particularly during drought. This project seeks to...

Ducks and other waterfowl in the U.S. are valued and enjoyed by millions of birdwatchers, artists, photographers and citizens for their beauty and appeal. Waterfowl also provide game for hunters throughout the country and act as an important source of revenue for states and local communities. Loss of habitat and migration corridors due to land use changes and changes in climate threaten these birds, however more scientific information is needed to understand these processes. This project used available annual surveys of duck counts, along with data on the location and availability of ponds and temperature and precipitation patterns, to model where across the continental landscape waterfowl were present and if their...

Broad scale banding of midcontinent greater white-fronted geese (MCWFG) is motivated by the Flyway Management Plan objective to maintain optimum harvest opportunity throughout the population range (Central, Mississippi, and Pacific Flyway Councils, 2023). This objective is accomplished by implementing a harvest strategy whereby changes to bag limits and season dates are dependent upon thresholds of abundance and harvest rate. Such estimates are calculated through Lincoln estimation (Lincoln 1930, Alisauskas et al. 2009, Dooley 2023) that requires annual banding. In addition, banding provides a means to identify changes in harvest distribution. The U.S. Fish and Wildlife Service (USFWS) Migratory Bird Management...

While habitat selection and population estimates are well documented for spring migrating birds in the central Platte River system, little information or monitoring efforts on the North Platte River exist, particularly for the multiple priority bird species known to be present. Most conservation partners deliver habitat programs in the region with limited information and a lack of a landscape prioritization tools. In order for conservation delivery to be more effective and efficient in utilizing limited funds, a decision support tool is critical so that priority species habitat needs are being addressed through appropriate restoration/management strategies in the correct geography at multiple scales. We propose...

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...

The Invasion of native communities by cool-season introduced grasses, especially smooth brome and Kentucky bluegrass in upland prairies, reed canary grass in wetlands, is on one of the most important management issues on U.S. Fish and Wildlife Service (Service)-owned lands. Two adaptive management projects, the Native Prairie and Reed Canary Grass Adaptive Management Projects were funded by USGS to examine restoration efforts on NWRs and WMDs in USFWS Regions 3 and 6. This project will support the completion of two decision support tools that are essential to long-term resource management success.
