Study Supports Single Introduction of Laurel Wilt Pathogen in the U.S.

Laurel wilt has devastated plants in the Lauraceae family – redbay, sassafras, pondberry, avocado, and others – since it was first detected in the southeastern U.S. around 2002. The disease is caused by the pathogen Raffaelea lauricola and carried by the redbay ambrosia beetle – and by humans moving infested wood. There is no widespread,…  More 

SRS Scientist Legacy: Continued Insect Research

A USDA Forest Service research scientist extended his 50 year legacy by donating more than a million dollars to each of his alma maters. John Moser’s research focused on understanding the biology of town ants (Atta texana), phoretic mites, and other associates of ants and pine bark beetles. Moser received his undergraduate and graduate degrees…  More 

A Hemlock in the Town Square

This summer, I joined USDA Forest Service scientist Andy Whittier for a day of field work as a part of my internship with SRS Public Affairs and Science Communications. We traveled to Green Mountain, NC to check up on an experiment led by research entomologist Bud Mayfield on hemlock trees. Throughout the eastern U.S., the invasive…  More 

The State of the Nation’s Forests

Forests are constantly changing with weather, disturbance, and conversion to other land uses, but how do we know if year-to-year changes are just a one-off or part of a larger shift? Annual summaries of forest health are key to our understanding, say the editors and authors that produced Forest Health Monitoring: National Status, Trends, and…  More 

State Line Meeting with Alabama, Louisiana, and Mississippi

On August 17 and 18, state foresters from Alabama, Louisiana, and Mississippi, along with their staffs and personnel from the U.S. Forest Service Southern Research Station (SRS), gathered in Biloxi, MS. This was the third State Line Meeting for state foresters Wade Dubea of Louisiana and Charlie Morgan of Mississippi, and the first for Alabama State…  More 

Where Are the Southern Pine Beetles?

Between 2005 and 2015, only 18 counties in the southern U.S. experienced southern pine beetle outbreaks–fewer than two outbreak counties per year on average. U.S. Forest Service entomologist Chris Asaro wanted to know why and worked with two other Forest Health Protection scientists, John Nowak and Anthony Elledge, on a new review paper published in Forest…  More 

Southern Pine Beetle Prevention Program

The U.S. Forest Service has teamed up with ESRI to create an exciting new tool for the Southern Pine Beetle (SPB) Prevention Program. This web-based application is called a storymap, which is designed for users to navigate through interactive maps accompanied by multimedia content and informative text. The information is provided by the Forest Health…  More 

Sap-sucking Bugs Threaten Hemlock Forests

Sap-sucking insects called hemlock woolly adelgids are draining the life from a common evergreen tree in the eastern United States. Since arriving from Japan in the 1950s, the tiny bugs have spread from Georgia to Maine—about half of the Eastern hemlock’s range. Once the bugs become well-established, the consequences can be grave. Areas with severe…  More 

Creating Oak Woodlands

Oak woodlands are typically made up of large, widely spaced trees. Flowering plants, grasses, and other herbaceous species flourish in the understory. “Many public lands managers want to create woodland habitats,” says U.S. Forest Service research forester Stacy Clark. “They provide numerous ecological benefits.” The historical extent of oak woodlands in southeastern forests is relatively…  More
