Prairies were once widespread across North America, but are now one of the most endangered and least protected ecosystems in the world. Agriculture and residential development have reduced once extensive prairies into a patchwork of remnant prairies and “surrogate” grasslands (e.g., hayfields, planted pastures). Grassland ecosystems and many grassland-dependent birds are also particularly vulnerable to rapid shifts in climate and associated changes in drought and extreme weather. The Central Flyway is a vast bird migration route that comprises more than half of the continental U.S., and extends from Central America to Canada, and harbors the greatest diversity of grassland birds in North America. Throughout this...

The USGS National Climate Change and Wildlife Science Center (NCCWSC) is currently engaged in an Ecological Drought initiative, focused on understanding the impacts of drought on natural ecosystems across the country. This project was designed to support the Ecological Drought initiative by creating a USGS EcoDrought Actionable Science Working Group. The goal of this working group was to identify science needs for drought-related decisions and to provide natural resource managers with practical strategies for adapting to and planning for drought. The working group engaged social scientists to garner advice on relevant social science research questions and data needs, as well as to identify any regulatory, institutional,...

Drought is a complex environmental hazard that impacts both ecological and social systems. Accounting for the role of human attitudes, institutions, and societal values in drought planning is important to help identify how various drought durations and severity may differentially affect social resilience to adequately respond to and manage drought impacts. While there have been successful past efforts to understand how individuals, communities, institutions, and agencies plan for and respond to drought, these studies have relied on extensive multi-year case studies in specific locations. In contrast, this project seeks to determine how social science insights and methods can best contribute to ecological drought...

Understanding the paths by which water flows through the landscape is critical for providing fresh water for human use, maintaining ecosystem function, and better predicting how disturbances such as fire or drought may impact water quantity and water quality. Yet projected changes in climate, disturbances, and land use , are likely to alter hydrologic flow paths, and .natural resource managers increasingly require information about projected changes in water flow paths to plan for the future. To meet this need, researchers will conduct a synthesis of changing hydrologic processes in the North Central region, and communicate the identified management options and opportunities to natural resource managers in federal...

Abundant scientific research has characterized the relationships between climate and fire in ecosystems of the United States, and there is substantial evidence that the role of fire in ecosystems is likely to change with a changing climate. Changing fire patterns pose numerous natural resource management challenges and decision makers in natural-resource management increasingly require information about potential future changes in fire regimes to effectively prepare for and adapt to climate change impacts. An effective forward-looking fire science synthesis is urgently required to reflect the changing dimensions of human fire management, recognizing that fire causes, effects, impacts, and management are all interrelated...

Drought events have cost the U.S. nearly $245 billion since 1980, with costs ranging from $2 to $44 billion in any given year. However, these socio-economic losses are not the only impacts of drought. Ecosystems, fish, wildlife, and plants also suffer, and these types of drought impacts are becoming more commonplace. Further, ecosystems that recover from drought are now doing so under different climate conditions than they have experienced in the past few centuries. As temperature and precipitation patterns change, “transformational drought”, or drought events that can permanently and irreversibly alter ecosystems – such as forests converting to grasslands – are a growing threat. This type of drought has cascading...

In ecosystems characterized by flowing water, such as rivers and streams, the dynamics of how the water moves - how deep it is, how fast it flows, how often it floods - have direct effects on the health, diversity, and sustainability of underlying communities. Yet increasingly, climate extremes like droughts and floods are disrupting fragile stream ecosystems by specifically changing their internal aquatic flows. Human infrastructure, such as irrigation and dams, further disrupt these dynamics. These changes in climate and land use are leading to teh fragmentation of aquatic habtiat, degraded water quality, altered sediment transport processes, variation in the timing and duration of floodplain inundation, shifts...

Changing climate conditions could have significant impacts on wildlife health. Shifts in temperature and precipitation may directly affect the occurrence of disease in fish and wildlife by altering their interactions with pathogens (such as the bacterium that causes Lyme disease), helping vectors like mosquitoes and ticks expand their range, or speeding up the time it takes for a parasite to develop from an egg to an adult. Climate change can also indirectly affect the health of fish and wildlife as their habitats change. For example, reduced food availability could lead to overcrowding and increased disease transmission, or warmer temperatures might increase stress levels, weakening immune systems and making animals...
