Estimating Ecosystem Water Use

For more than a decade, U.S. Forest Service and Chinese scientists have collaborated to understand how human activities affect carbon and water cycles in managed ecosystems. Working through the U.S.-China Carbon Consortium, scientists share data from a network of eddy covariance flux towers across the two countries. The towers measure the flow of water vapor,…  More 

Air Pollution Could Worsen Water Shortages in a Changing Climate

Over the past 40 years since the passage of the Clean Air Act, air pollution from automobiles, factories, and power plants has substantially decreased, leading to better human and environmental health. But air pollution and its impacts on people and ecosystems remain a concern amid growing demands for transportation, energy, and manufactured goods. University and…  More 

Mississippi Alluvial Valley Forests

The Southern Forest Futures Project (SFFP) started as an effort to study and understand the various forces reshaping the forests across the 13 states of the Southeast. Chartered by the U.S. Forest Service Southern Region and Southern Research Station (SRS) along with the Southern Group of State Foresters, the project examined a variety of possible…  More 

White Pines, Hemlocks, and Sunlight

The Blue Valley Experimental Forest (Blue Valley) lies in southwest North Carolina in the Nantahala National Forest. Located in Macon County, near the point where North Carolina meets Georgia and South Carolina, the experimental forest was established in 1964. At 1,300 acres, it is the smallest of the three experimental forests in North Carolina and the second smallest…  More 

Mount Ascutney Visitors Enjoy the View and Learn Something, Too

Over the past decade, countless visitors on southeastern Vermont’s Mount Ascutney have read the words on two interpretive panels describing ongoing research that began as a graduate student’s research project there. Through the years, the panels have faded and weathered, but now they are new again after U.S. Forest Service researchers installed updated replacements in…  More 

After the Fire, What Happens to Water Yield?

The immediate impacts of large and severe wildfires on water runoff have long been known to researchers, land managers, and, increasingly, the communities in their path. Devastating mudslides and millions of dollars in flood damage occur each year following fires that compromise vegetation and soils that would otherwise absorb and regulate the flow of post-fire…  More 

After the Acid Rain

“Rain has become much less acidic since the Clean Air Act was strengthened in the 1990s,” says U.S. Forest Service Southern Research Station (SRS) soil scientist Jennifer Knoepp. “However, some high elevation streams still have chronic or episodic acidity.” Acid rain, as well as other forms of acidic deposition such as acid fog and acid…  More 

In South Carolina, Coyotes Not a Threat to Adult Deer

In parts of the northeastern U.S., white-tailed deer populations have ballooned. Not so in parts of the southeastern U.S., such as South Carolina, where the statewide deer population has been declining for about 12 years. “In the Southeast, coyotes often prey on white-tailed deer fawns,” says U.S. Forest Service research wildlife biologist John Kilgo. “There…  More 

An Assignment in Africa Connects Forests, Water, and People

Steve McNulty, Ge Sun, and Erika (Cohen) Mack hiked for three hours on a winding trail over steep hills through land thick with trees and vines. They arrived at a pool and looked up at a towering waterfall. If they had stood at the top of the waterfall, they would have seen forested land stretching…  More 

Forests, Water, Climate, and Management

Across the globe, forests cover about a quarter of all land and are important sources of clean water. A new book, edited by U.S. Forest Service Southern Research Station (SRS) scientist Devendra Amatya, examines the interactions between forests, water, climate, and management. The book, Forest Hydrology: Processes, Management and Assessment, was recently published by the…  More
