Loss of Hemlocks Will Affect Water Dynamics in Southern Appalachian Forests
Forest Service (FS) research has provided the first estimates on the impact the loss of eastern hemlock will have on the water dynamics of the southern Appalachian mountains. view more (2007-07-10)
Study finds hemlock trees dying rapidly, affecting forest carbon cycle
New research by U.S. Forest Service Southern Research Station (SRS) scientists and partners suggests the hemlock woolly adelgid is killing hemlock trees faster than expected in the southern Appalachians and rapidly altering the carbon cycle of these forests. view more (2009-02-27)
Japanese beetle may help fight hemlock-killing insect
The eastern hemlock, a tall, long-lived coniferous tree that shelters river and streamside ecosystems throughout the eastern United States and Canada, is in serious danger of extinction because a tiny, non-native insect is literally sucking the life out of it. view more (2007-09-11)
Fungal factories may save hemlock forests
Reaching into a box glowing with fluorescent light, Stacie Grassano pulls out a tube. "This is a great one," she says, holding the clear plastic up to her face. Inside, a tree branch is speckled with white fluff. "It's growing really well," she says, handing it to Scott Costa. view more (2007-01-29)
Forest fire prevention efforts will lessen carbon sequestration, add to greenhouse warming
Widely sought efforts to reduce fuels that increase catastrophic fire in Pacific Northwest forests will be counterproductive to another important societal goal of sequestering carbon to help offset global warming. view more (2009-07-09)
Vineyard weeds found to host Pierce's disease of grapes
New research just released in the September issue of Plant Disease suggests that weeds commonly found in California's wine country may enable the spread of Pierce's disease of grapes, one of the most destructive plant diseases affecting grapes. view more (2005-09-22)
Tree Species Composition Influences Nitrogen Loss From Forests
Throughout the world, nitrogen compounds are released to the atmosphere from agricultural activities and combustion of fossil fuels. view more (2009-03-17)
Rhododendron expansion may increase the chance of landslides on Southern Appalachian slopes
Research by U.S. Forest Service Southern Research Station (SRS) scientists and partners suggests that the expansion of rosebay rhododendron (Rhododendron maximum) in Southern Appalachian mountain hollows may increase the likelihood of landslides during and after intense rain events. view more (2009-08-31)
