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 

Lizards or Salamanders?

The southern Appalachians are crawling with salamanders. In western North Carolina alone, more than 45 species can be found, and they are critical members of food webs – both as predators and as prey. Salamanders and other amphibians, as well as reptiles, can be affected by forest management practices. “However, amphibians and reptiles are ecologically,…  More 

Alum Creek Experimental Forest

The 4,660-acre Alum Creek Experimental Forest (Alum Creek) was established in the late 1950s in the upper headwaters of the Lake Winona Basin near Jessieville, Arkansas. Managed by the U.S. Forest Service Southern Research Station Southern Pine Ecology and Management unit, Alum Creek is affiliated administratively with the Ouachita National Forest. From 1960 until the…  More 

The Crossett Experimental Forest

Since it was established in 1934, the Crossett Experimental Forest has served as the repository of silvicultural alternatives to the intensive plantation methods that dominate industrial forestry on the Coastal Plain. The not-so-hidden secret of southern forestry is that naturally regenerated Coastal Plain loblolly-shortleaf pine is one of the Nation’s most pliable forest types, able…  More 

Dry Air May Be More Stressful to Trees than Dry Soil

Scientists forecast that for many parts of the U.S., climate change will bring higher temperatures and more frequent and severe periods of drought. In parts of the West, forests are already changing as a result of drought, but all U.S. forests may be impacted, in turn affecting other important resources such as clean air and…  More 

More Benefits of Cool Mountain Air

In mountainous areas, cold air flows along the surface of the earth from mountain tops to valleys, and as it moves, it dramatically affects local temperatures. “Many ecosystem processes – including carbon uptake and storage – are affected by temperature,” says U.S. Forest Service research ecologist Chris Oishi. Oishi recently contributed to a study on how…  More 

Digging up Past Connections at Bent Creek

A rock protruding through the grass in the lawn at the Bent Creek Experimental Forest was the beginning of a part time, amateur archaeology “dig” for Senior Community Service Employment Program (SCSEP) employee, Linda Benz. It is well known that rocks and whirling lawn mower blades are a bad combination, so when Linda noticed an exposed…  More 

The Stephen F. Austin Experimental Forest

Located seven miles west of Nacogdoches, Texas, the 2,560-acre Stephen F. Austin Experimental Forest (Stephen F. Austin) was established by an act of Congress in 1945. For its first 15 years, the experimental forest was primarily used for research that improved methods for growing loblolly and shortleaf pine. In 1949, 40 acres were set aside as…  More 

The Chipola Experimental Forest

Located in the sandhills of the Florida Panhandle, the Chipola Experimental Forest (Chipola) was established in 1952 on privately owned land under a 99-year lease to the Southern Forest Experiment Station (now the Southern Research Station), International Paper Company, and Hardaway Contracting Company. The two companies requested the cooperative arrangement with the Forest Service to…  More 

Developing a Network of the South’s Experimental Forests

For decades, scientists on the 19 experimental forests of the U.S. Forest Service Southern Research Station (SRS) have investigated research questions that are as diverse as the experimental forests themselves. Research topics include forest management and regeneration; restoration of wildlife and plant populations; watershed management; and the effects of pollution, climate change, and timber harvest.…  More
