SRS Scientists Contribute to New National Report

Study projects significant forest loss due to suburbanization and land fragmentation A comprehensive U.S. Forest Service report released on December 18 examines the ways expanding populations, increased urbanization, and changing land-use patterns could profoundly impact natural resources, including water supplies, nationwide during the next 50 years.  Forest Service Southern Research Station scientists who took lead roles in conducting…  More 

Invasive Earthworms, No Joke

Earthworms, the darlings of gardeners, fishers and composters, have a dark side: some are globetrotters and when introduced to new homes can cause real problems, both above and below ground. “Invasive earthworms are a global problem and can cause considerable changes to ecosystems,” says Mac Callaham, research ecologist with the U.S. Forest Service Southern Research…  More

Numerous studies have addressed causes of the decline, but very few have looked at the effects of invasive plants. Dan Saenz, Southern Research Station (SRS) research wildlife biologist…  More 

Forest Service Termiticide Testing Program

Termites cause an estimated $5 billion in damages in the United States every year. In the South, where termite damage is legendary, proof of treatment for the insects is often required before a home can be sold. Many people assume that termites are just urban or suburban pests and are surprised to learn that the Forest Service…  More 

Cytogenetics and the Fate of Trees

  Nurul Islam-Faridi, research geneticist with the Southern Research Station (SRS) Forest Tree Molecular Cytogenetics Laboratory on the Texas A&M campus at College Station, TX, and adjunct professor in the university’s Department of Ecosystem Science and Management, is one of a handful of scientists in the world who can literally count the chromosomes inside the living cells of any…  More 

Ozone Effects on Forest Watersheds in the Southeast

  Southern Research Station (SRS) and Oak Ridge National Laboratory (ORNL) scientists have found that rising levels of ozone, a greenhouse gas, may amplify the impacts of higher temperatures and reduce streamflow from forests to rivers, streams, and other water bodies. Such effects could potentially reduce water supplies available to support forest ecosystems and people…  More 

Testing the Survival of American Chestnut Seedlings

The American chestnut tree (Castanea dentata) dominated the forest canopy in the eastern United States for thousands of years, until it was decimated by an exotic fungal pathogen, the chestnut blight (Chryphonectria parasitica) in the early part of the 20th century. Since then, tree enthusiasts and scientists have been trying to find a way to…  More
