New Guide to Woodwasps of the Western Hemisphere

Includes DNA barcodes for early detection of major pests The North American forest community reacted with alarm when specimens of Sirex noctilio Fabricius were found in New York State in 2004.  Native to Europe, Asia and northern Africa, S. noctilio—a species of woodwasp in the family Siricidae—is fairly benign in its native range, but as a…  More 

Mapping Species Invasions

Forest Service scientists help organize international meeting. Eastern Forest Environmental Threat Assessment Center research ecologist Frank Koch and Northern Research Station research biologist Robert Venette, and international colleagues co-organized the sixth annual International Pest Risk Mapping Workgroup (IPRMW) held July 23-26 in Norway. The IPRMW is a group of like-minded scientists focused on improving the…  More 

Seeing Forest Stress from Drought in Real Time

Most climate change models predict drier and warmer conditions across parts of the southern United States, which may translate into more frequent and severe drought events for those areas. With an estimated 60 percent of the drinking water of the South coming from forested watersheds—and many forests already stressed—land managers need to start planning now…  More 

Klepzig Recieves A.D. Hopkins Award

  Dr. Kier Klepzig, Southern Research Station (SRS) Assistant Director is the recipient of the A.D. Hopkins Award, which is presented to individuals who have an outstanding record of service to Southern forest entomology.  Klepzig received the award from the Southern Forest Insect Work Conference at the groups annual meeting, held this year in Charlottesville,…  More 

Dogwoods in Decline?

  Dogwood trees are cherished across the southeastern United States for their showy spring flowers. The small, deciduous trees are often found in the understory of hardwood forests, where they shuttle calcium from far below ground to leaves. Each fall, the calcium-rich leaves fall to the forest floor and decompose, enriching the topsoil with minerals.…  More 

Forest Detectives Solve Asheville Watershed Mystery

  Scientists with the USDA Forest Service Eastern Forest Environmental Threat Assessment Center (EFETAC) headquartered at the Southern Research Station in Asheville, North Carolina, recently discovered an area of damaged trees within the watershed from which Asheville draws most of its water supply. Though monitoring forest health is an everyday role of the Forest Service,…  More 

Trees in Transition

In forests as in life, the only constant is change. Forest species are ever adjusting to changing conditions resulting from seasonal fluctuations in temperature and precipitation, disturbances such as storms and wildfire, and interactions with other species. But typical temperature and precipitation patterns are now also changing; in some areas, climatic changes are occurring rather rapidly,…  More 

Unwelcome Pests Often Hitch a Ride

EFETAC and Canadian Researchers Investigate the Firewood Connection Firewood has ignited a national debate, especially in campgrounds, because it can carry unwanted forest insect pests across state borders and potentially even between the United States and Canada. Many of these nonnative pests are well-known—hemlock woolly adelgid, emerald ash borer, Asian longhorned beetle—for causing significant ecological and…  More 

A ForWarning

 USDA Forest Service and NASA team up to monitor forests from space About 750 million acres of forests stretch across the United States—lands that are vulnerable to disturbances caused by insects, diseases, wildfires, extreme weather, or other natural or human-caused events. Some disturbances are immediately evident in the landscape when they occur; others are more…  More 

Manager Resources: The Climate Change Resource Center (CCRC)

Science You Can Use Are you a land manager wondering about what you can do about climate change? The Climate Change Resource Center (CCRC) can provide you with real, on-the-ground answers. Changing weather patterns already impact forests across the United States, and future effects are expected to be even greater. Although planning for future scenarios…  More
