Water Tables and Wetlands

Some wetlands won’t stay wet, according to new research that blends long-term observations and climate projections. “By end of the 21st century, all five of the wetland sites we studied are predicted to become much drier,” says USDA Forest Service research hydrologist Ge Sun. The five wetlands are long-term research sites located throughout the southeastern…  More 

Projections of Future Climate and Annual Runoff

Hydrologists have traditionally relied on historic precipitation data to estimate broad-scale runoff. “Rainfall was always number one,” says USDA Forest Service scientist Ge Sun. “But things are changing and getting more complicated.” Sun co-authored a recent modeling study that investigated how other climate factors might influence future changes in runoff. The researchers were intrigued by…  More 

Shifting Rainfall Patterns May Change Southern Appalachian Forest Structure

A new research study by U.S. Forest Service scientists finds that changes in rainfall patterns in the southern Appalachians due to climate change could reduce growth in six hardwood tree species common to the region. The findings have implications for forest managers in the Southeast, where climate variability (more extreme events or changes in precipitation…  More
