Grasslands in the northern Great Plains are important ecosystems that support local economies, tribal communities, livestock grazing, diverse plant and animal communities, and large-scale migrations of big game ungulates, grassland birds, and waterfowl. Climate change and variability impact how people and animals live on and interact with grasslands, and can bring more frequent droughts, fires, or new plant species that make managing these landscapes challenging. Understanding how climate change and variability will impact grassland ecosystems and their management in the 21st century first requires a synthesis of what is known across all of these scales and a gap analysis to identify key areas of focus for future...

As climate change progresses, profound environmental changes are becoming a widespread concern. A new management paradigm is developing to address this concern with a framework that encourages strategic decisions to resist, accept, or direct ecological trajectories. Effective use of the Resist-Accept-Direct (RAD) framework requires the scientific community to describe the range of plausible ecological conditions managers might face, while recognizing limits to our ability to predict precisely where or how specific climatic changes may unfold or how complex environmental systems will respond - the climatic future does not fully determine the ecological one. Recent advances have improved development and delivery...

Pinyon pine woodlands are among the most widespread and iconic vegetation types in the western United States and support recreation, resource extraction, grazing, and cultural enrichment. However, severe drought conditions have recently caused dramatic mortality of pinyon pines, creating concern about the long-term impact of increasing aridity on the viability of pinyon woodlands. Ecological transformations, or regime shifts, are rapid reorganizations of an ecosystem’s species composition, governing processes, and functions. The goal of this project is to investigate ecological transformation across the Western U.S, characterize the environmental drivers of these changes in vegetation, and apply those insights...

Prairie dog colonies in North America’s Central Grasslands undergo cycles of collapse and recovery caused by the non-native sylvatic plague, and each phase of the cycle negatively affects wildlife or livestock. Researchers supported by this North Central-CASC project will develop a decision-support web tool for users to predict prairie dog colony dynamics under changing climatic conditions to help optimize management strategies of wildlife and cattle. Prairie dogs are crucial to North America’s Central Grasslands, creating habitat for other wildlife by digging burrows and clipping vegetation, and serving as a key food source for many predators. However, the sylvatic plague, a non-native disease with over 99% mortality...

Ecological drought impacts ecosystems across the U.S. that support a wide array of economic activity and ecosystem services. Managing drought-vulnerable natural resources is a growing challenge for federal, state and Tribal land managers. Plant communities and animal populations are strongly linked to patterns of drought and soil moisture availability. As a result, ecosystems may be heavily altered by future changes in precipitation and soil moisture that are driven by climate change. Although this vulnerability is well recognized, developing accurate information about the potential consequences of climate change for ecological drought is difficult because the soil moisture conditions that plants experience are...

A rapidly changing climate during this century poses a high risk for impacts to ecosystems, biodiversity and traditional livelihoods. A better understanding of how climate change might alter temperature, precipitation, heat stress, water availability and other extreme weather metrics in the coming century would be useful to natural resource managers at the U.S. Fish & Wildlife Service in the North Central region. Particularly, when they prepare to conduct Species Status Assessments to better evaluate risk to ecosystems, biodiversity and traditional livelihoods resulting from a changing climate. Scientists have traditionally gone through the time intensive process of extracting and analyzing different climate datasets...
