The Future of Fish in the NC Piedmont

What will fish communities of the North Carolina Piedmont look like in the future? “Many factors could affect this,” says U.S. Forest Service research hydrologist Peter Caldwell. “Water withdrawals could be one of the most important.” Water withdrawn from rivers may eventually flow out of kitchen faucets. Many municipalities get drinking water from rivers and…  More 

Climate Influences Male-Female Balance in Longleaf Pines

For many reptile and fish species, temperature during egg incubation determines whether hatchlings are male or female. In the northern part of Australia’s Great Barrier Reef, scientists have discovered that 99 percent of immature green turtles hatched in warming sands are female, raising concerns about successful reproduction in the future. U.S. Forest Service scientists have…  More 

Daily Precipitation Patterns Are Changing at Coweeta

Since 1950, heavy rains have become more common in the southern Appalachians. U.S. Forest Service researchers have witnessed such changes at Coweeta Hydrologic Laboratory. Coweeta was established in 1934. Its location in the mountains of western North Carolina is no accident – early Forest Service researchers strategically selected it. “Coweeta receives as much as 90…  More 

Conserving Eastern Hemlock

Where can you go to find an eastern hemlock tree? Although threatened by the hemlock woolly adelgid, eastern hemlock has an extensive range. “Eastern hemlock grows throughout the southern Appalachians,” says U.S. Forest Service collaborator and ecologist Kevin Potter. Potter is also a forestry faculty member at North Carolina State University. “Hemlock grows in the…  More 

Frogs, Toads, and Ephemeral Wetlands

When ephemeral wetlands swell with water, frogs and toads congregate to breed and lay their eggs,which hatch into tadpoles. “That’s risky business,” says U.S. Forest Service research ecologist Katie Greenberg. “Wetlands could dry before tadpoles metamorphose into juveniles.” If ephemeral wetlands dry out before the tadpoles develop lungs and become froglets or toadlets, an entire…  More 

Air, Water, and Wavelets

We know air temperature has increased over the last 15-20 years, and that it will continue to do so on an unprecedented scale. But we are still learning exactly how this air trend impacts water. As it turns out, air temperature is linked to changes in our streams — affecting things like flow, soil moisture,…  More 

National Silviculture Workshop

In 1973, foresters and scientists gathered for the first U.S. Forest Service National Silviculture Workshop. Since 1979, the workshop has been held every two years. The workshop brings two branches of the U.S. Forest Service – the National Forest System and Research & Development – together to address silvicultural challenges. University scientists and managers from…  More 

Drier Weather, Drier Fuels

Dry weather – and huge wildfires – are common. “Climate change would modify fuel moisture and wildland fires dramatically across the United States,” says Yongqiang Liu. Liu is a U.S. Forest Service research meteorologist who recently investigated climate impacts on fuel moisture. His study was published in the journal Ecohydrology. Weather quickly influences fuel moisture…  More 

Eastern Trees Move North & West

After analyzing extensive data collected on 86 tree species in the eastern U.S., researchers found that most trees have been shifting their ranges westward or northward in response to temperature and precipitation changes. Scientists from Purdue University, North Carolina State University, and the U.S. Forest Service collaborated on the study, which was recently published in…  More 

The Most Vulnerable Trees

What do water locust, Texas walnut, chalk maple, pyramid magnolia, two-wing silver bell, and butterbough all have in common? They’re among the U.S. tree species most vulnerable to climate change, according to a study by North Carolina State University (NCSU) and the U.S. Forest Service. The Forest Service Forest Health Protection program sponsored the study,…  More
