Fragmented Forests

The Southern Forest Resource Assessment published by the Southern Research Station defined forest fragmentation as the breaking up of large, contiguous (touching one another) forested tracts into smaller or less contiguous tracts. This means that forests become islands or peninsulas — patches of woods disconnected from one another by roads, farms, suburbs, cities, and other…  More 

Interior Forest on the Wane in the United States

Interior forest, which can be simply defined as forest area surrounded by more forest, supports a wide range of plants and animals that do not thrive in forest edges or the small patches of woods left by human activities. Many of the nations most important rivers originate in interior forest, which also shelters municipal watersheds and…  More 

More Fuel for Fire?

Fire has been a fact of life for millennia in the South, shaping the range and ecology of pine, certain oak, and palm forests. But along with shrinking polar ice and rising sea levels, there’s general agreement among climate scientists that climate change will probably increase both the intensity and frequency of fire in the southern…  More 

What Comes After Hemlock Woolly Adelgid?

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 

CRAFTING Future Forests

Over the past few years, Eastern Forest Environmental Threat Assessment Center (EFETAC) scientists have developed and refined a new resource, the Comparative Risk Assessment Framework and Tools (CRAFT), designed to help natural resource managers and stakeholders work through land management decisions and find common ground, sometimes by coming up with unexpected solutions. EFETAC launched CRAFT as…  More

Key members of the group are John Nowak (team leader), Don Duerr, Wes Nettleton, and Linda Brett from Forest Service, Region 8, and Kier Klepzig, Assistant Director for Research at the Southern Research Station. …  More 

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
