Projecting Changes in Snow, Lake Ice, and Winter Severity in the Great Lakes Region for Wildlife-Based Adaptation Planning

Winter conditions have changed substantially in the Great Lakes region over the last 50 years, with the region experiencing rising temperatures, declining lake ice cover, and increased lake-effect snow. These changes have direct implications for economically important wildlife, such as deer and waterfowl. Deer hunting alone contributes $482 million annually to Wisconsin’s economy. The...

Projecting the Effects of Climate Change on Aspen in the Central and Northern Rocky Mountains

Aspen is an environmentally, economically, and socially important species in the western U.S. It is typically the most abundant deciduous tree species in mountainous landscapes of the western U.S., providing food and habitat for a variety of wildlife, including black bear, deer, elk, moose, and numerous bird species. Aspen woodlands also provide high quality forage for livestock and draw...

Science to Assess Future Conservation Practices for the Mississippi River Basin

USFWS Landscape Conservation Cooperatives (LCCs) throughout the Mississippi River Basin (MRB) have identified high nutrient runoff, a major contributor to Gulf hypoxia, and declines in wildlife populations (especially grassland and riparian birds), as conservation challenges requiring collaborative action. This project aimed to develop a spatial decision support system (DSS) to address...

Science to Inform Management of Floodplain Conservation Lands in a Changing World

Recent extreme floods on the Mississippi and Missouri Rivers have motivated decision-makers and resource managers to expaned floodplain conservation lands. Within Missouri, there are more than 85,000 acres of public conservation lands in large-river floodplains. Floodplain lands are highly dynamic and challenging to manage, particularly climatic conditions change. These lands have the...

Spatial Conservation Priorities for Riverine and Riparian Systems in the Columbia Plateau Ecoregion

This project identified priority areas in the Columbia Plateau Ecoregion to focus on for riverine and riparian habitat conservation. The project’s products are tailored towards the Arid Lands Initiative (ALI) conservation goals and objectives and provide the foundation for adaptation to a changing climate. We adopted a “zoned” approach to identifying focal areas, connectivity management...

The Past as a Prelude to the Future: Assessing Climate Effects on Native Trout in the U.S.

Salmonids (a family of fish that includes salmon, trout, and char) are a keystone species for both aquatic and terrestrial ecosystems, and can be an early warning indicator of ecosystem health. Salmonids also have strong societal values and contribute enormously to regional economies and Native American cultures. Today, many native salmonid populations are small, highly fragmented, and...

Yukon River Basin Indigenous Observation Network

The hydrology of the Yukon River Basin has changed over the last several decades as evidenced by a variety of discharge, gravimetric, and geochemical analyses. The Indigenous Observation Network (ION), a community-based project, was initiated by the Yukon River Inter-Tribal Watershed Council and USGS. Capitalizing on existing USGS monitoring and research infrastructure and supplementing...

Application of an Adaptive Management Plan to Reduce Uncertainty and Improve Decisions in Restoring the Herring River Estuary

Located between Wellfleet and Turo, Massachusetts, the 1100-acre Herring River watershed has historically provided many ecological and social benefits, including forest and wetland habitat for native fish, birds, and mammals and recreational and educational opportunities for residents and visitors. Construction of a dike and ditches beginning in the early 1900s constricted tidal exchange...

Assessing Climate Change Impacts on Pacific Lamprey and Pacific Eulachon

For thousands of years, Pacific lamprey and Pacific eulachon have been important traditional foods for Native American tribes of the Columbia River Basin and coastal areas of Oregon and Washington. These fish have large ranges – spending part of their lives in the ocean and part in freshwater streams – and they require specific environmental conditions to survive, migrate, and reproduce...

Assessing the Drivers of Water Availability for Historic and Future Conditions in the South Central U.S.

Understanding the changes in the distribution and quantity of, and demand for, water resources in response to a changing climate is essential to planning for, and adapting to, future climatic conditions. In order to plan for future conditions and challenges, it is crucial that managers understand the limitations and uncertainties associated with the characterization of these changes when...
