Species are adapted to particular environmental conditions, but are threatened as climate change shifts habitat conditions. One way species can respond is by moving to new suitable locations, known as climate-driven range shifts. But some species can move more easily and/or more quickly than others, and some landscapes are more difficult to cross. In the upper Midwest, the movement potential of many species is reduced by broad expanses of row-crop agriculture, roads and other types of development that fragment the remaining habitat. It is important to sustain and improve connectivity across landscapes so they can continue to support biodiversity and ecosystem services like water filtration, carbon storage, pollinator...

Prescribed burning – planned, controlled fires conducted under weather and fuel conditions designed for safety and effectiveness – is a common practice used to maintain and restore native prairies in the Northern Great Plains. However, climate change will affect the number of days in a year, and when, suitable conditions for prescribed fires occur. For instance, warmer temperatures may shift these “good prescribed-fire days” earlier in the spring and later in the fall, but uncertainty about future climate makes it hard to predict how large shifts will be and if the number of good fire days each year will generally increase or decrease. Further, it’s hard to know whether prescribed fires will continue to achieve...

Invasions of exotic annual grasses (EAGs like cheatgrass have caused major losses of native shrubs and grasses in western U.S. rangelands. They also decrease the productivity and carbon storage in these ecosystems, which is expected to create dryer soils that may cause further losses in plant productivity. This cycle is the hallmark of desertification – or, fertile lands turning into deserts. Management actions that target EAGs are one of the most widespread land management actions taken in Western U.S. rangelands, but it is unclear which specific actions can simultaneously enhance drought resilience of native plant communities and increase carbon sequestration and storage. This project aims to identify the restoration...

Inland fisheries have tremendous cultural, economic, and subsistence value. However, climate change brings new stresses to land-locked fisheries that raise novel challenges for resource managers. One fundamental challenge in inland fisheries is how to best assess and manage data-limited fisheries when resources are finite and uncertainty is pervasive. To address this challenge, we will use quantitative models to examine whether indicators of fish population status commonly-measured by managers can serve as a “short-cut” to more data- and capacity-intensive approaches. Further, we will work and communicate directly with state and Tribal fisheries managers to better understand the challenges they face when making...

Water levels in the Great Lakes are fluctuating in ways that we have not seen in the past, with both historically low- and high-water levels occurring in the last decade. Expectations are that larger and more frequent water-level fluctuations will occur in response to climate change. The increased variability in lake levels has implications for the management of invasive plants found in the coastal wetlands that surround the Great Lakes, with some species benefiting from periods of low water levels. Phragmites australis, a prominent invasive grass that disrupts fish and wildlife habitats, thrived during the most recent period of low lake levels. However, periods of high lake levels could provide managers with opportunities...
