Does Carbon in Wetland Soils Go With the Flow?
Hidden in wetland soils is a critically important benefit: storage of carbon that would otherwise enter the atmosphere as carbon dioxide (CO2), a climate-warming greenhouse gas. But what happens to this carbon when wetlands dry out because of seasonal water level fluctuations, climate variability, or land use changes related to human development? In a recently published study, researchers from North Carolina State University and the Eastern Threat Center characterize the factors that drive soil carbon loss as the water table rises and falls in a seasonally flooded, forested wetland.

Forest Service and Tribes Meet to Bridge a Gap Across Lands
When tribal elders and natural resource managers come together with the Forest Service and other federal agencies, informal discussions serve to broaden goals for sustaining the environment, explains Serra Hoagland in an interview recorded at the 2014 To Bridge A Gap conference, an annual event held around the nation to facilitate such discussions. In the interview, which aired on KUAF public radio, Hoagland and Northern Research Station scientist Mike Dockry highlight tribes' traditional knowledge and practices that contribute to and serve as a model for sustainable natural resource management.

Researchers Turn Up the Heat on Thousand Cankers Disease
Black walnut trees are prized by people and wildlife alike, but these trees are under threat in the eastern United States due to thousand cankers disease, the result of an invasive fungus carried by the walnut twig beetle. The Eastern Threat Center provided support for a Southern Research Station-led project to test heat treatments for black walnut logs. In this recently published study, researchers determined the minimum temperature and heating time required to eliminate pests and prevent the spread of thousand cankers disease if logs are transported.
