The key word is “appear,” said Talbot Trotter, the study’s lead author and a research…  More 

Loss of Eastern Hemlock Will Affect Forest Water Use

by Sarah Farmer, SRS Science Delivery Group  • 
Eastern hemlock grows in streamside areas throughout the southern Appalachian Mountains, where it is a keystone species. Because of its dense evergreen foliage, constant year-round transpiration (loss of water from needles) rate,  and dominance in riparian and cove habitats,  eastern hemlock plays an important role in the area’s water cycle, and regulates stream flow year…  More 

Managing For Hemlock Woolly Adelgid

by Patty Matteson, SRS Science Delivery Group  • 
The nonnative invasive insect hemlock woolly adelgid is taking its toll on eastern hemlock trees in the Southern Appalachian region of the United States, where the tree often serves as a foundation or keystone species along mountain streams. A new article by U.S. Forest Service researchers covers the latest in control strategies for hemlock woolly…  More 

What Comes After Hemlock Woolly Adelgid?

by Patty Matteson, SRS Science Delivery Group  • 
The hemlock woolly adelgid, an exotic invasive insect that feeds on eastern and Carolina hemlocks, now occupies about half the range of native hemlock forests in the eastern United States. Once infested, hemlocks lose vigor and die within a 4 to 10 years. Most managers and scientists accept that as time goes on native hemlocks…  More
