Chinese Tallow Litter and Tadpoles

Centuries ago, a tree was plucked out of its native ecosystems and introduced to the U.S. Chinese tallow (Triadica sebifera) is a showy tree with waxy seeds and heart-shaped leaves. Every autumn, its leaves turn crimson or orange before falling to the ground – or the water. “Chinese tallow invades wetlands and riparian areas in…  More 

Climate Influences Male-Female Balance in Longleaf Pines

For many reptile and fish species, temperature during egg incubation determines whether hatchlings are male or female. In the northern part of Australia’s Great Barrier Reef, scientists have discovered that 99 percent of immature green turtles hatched in warming sands are female, raising concerns about successful reproduction in the future. U.S. Forest Service scientists have…  More 

Experimental Forests’ Road Data Go Digital

Many national and experimental forests are crisscrossed by gravel roads that contain culverts and other drainage structures. Some culverts may be overdue for maintenance, while others may be too small for extreme rainfall events. U.S. Forest Service Southern Research Station scientists began assessing the capacity of these structures in 2016. The project spans the SRS…  More 

A Tour of SRS Experimental Forests

For some, the term experimental forest may conjure images of petri dishes on the forest floor. “It’s true that Experimental Forests are living laboratories,” says U.S. Forest Service scientist Stephanie Laseter. “SRS manages 19 experimental forests. Each one represents a specific ecosystem and provides unique research opportunities.” Laseter recently organized a five-day tour of eight…  More 

Highlights from the Joint Leadership Team Meeting

On August 30, the U.S. Forest Service Southern Regional Leadership Team met with the Southern Research Station Leadership Team in Asheville, NC. Ken Arney, deputy regional forester, kicked off the day with a recap of the last joint meeting held in 2015. Several priority topics from that forum are still of great importance: longleaf pine…  More 

Forestry’s Early Entrepreneurs

Before the Crossett Experimental Forest existed, two engineers-turned-lumbermen began rehabilitating the cutover ‘pineywoods.’ “In 1925, Leslie Pomeroy and Eugene Connor bought the Ozark Badger Lumber Company,” says U.S. Forest Service scientist Don Bragg. “The company was small and nearly defunct, and Pomeroy and Connor turned it into a profitable, long-term example of uneven-aged silviculture.” Bragg…  More 

Experimental Forest Network Engages New Partners

For the past 18 months, the SRS Experimental Forest network has been working to create scientific linkages across the Station and Region. The idea of a formal network was rolled out at the inaugural meeting in March 2016. The network is linking sites strategically across geographic domains and environmental gradients. U.S. Forest Service Experimental Forests,…  More 

White Pines, Hemlocks, and Sunlight

The Blue Valley Experimental Forest (Blue Valley) lies in southwest North Carolina in the Nantahala National Forest. Located in Macon County, near the point where North Carolina meets Georgia and South Carolina, the experimental forest was established in 1964. At 1,300 acres, it is the smallest of the three experimental forests in North Carolina and the second smallest…  More 

Forests, Water, Climate, and Management

Across the globe, forests cover about a quarter of all land and are important sources of clean water. A new book, edited by U.S. Forest Service Southern Research Station (SRS) scientist Devendra Amatya, examines the interactions between forests, water, climate, and management. The book, Forest Hydrology: Processes, Management and Assessment, was recently published by the…  More 

The Koen Experimental Forest

  Established in 1951 in northern Arkansas, the Henry R. Koen Experimental Forest (Koen) is covered mostly in oak-hickory upland hardwood forest and oak-pine stands. Named for Henry R. Koen, forest supervisor of the Ozark National Forest during the first half of the 20th century, the experimental forest was set aside to develop scientific principles for forest…  More
