Research Ecologist Chris Oishi discusses techniques for measuring sap flux, and introduces a new processing program that can help interpret and normalize this data.
The USFS research station in Otto, has been recording watershed data every five minutes since 1934. The information reveals a lot about climate change and drought issues.
Smokey's message is clear now - don't start a forest fire. He makes no judgement about whether or not the fire itself is good or bad. That's because we know how important fire is for the ecosystem.
The eastern United States' mightiest tree, the oak, is in decline, possibly due to over-harvesting or climate change. Whatever the cause, scientists are trying to find ways to reverse this decline. Watch U.S. Forest Service researcher Tara Keyser and others use fire to give young oaks room to grow in the North Carolina mountains.
A Plan for the North American Bat Monitoring Program (NABat) provides detailed guidelines for participating in NABat, an international multiagency program created to provide the data needed to make effective decisions about bat populations across the North American continent.
Susan Loeb, SRS research ecologist, served as lead author on the new publication, which represents the first step in establishing the NABat monitoring program for bats in North America.
To meet our obligations to the public, we’re developing a new and visually engaging portfolio of tools and applications. View the video introduction to our Engagement Portfolio.
The Appalachian Mountains, with dense forest cover, make western North Carolina a unique laboratory from which to monitor air quality and atmospheric conditions and their impact on ecosystems.
Scientist Don Bragg discusses how restoration efforts are now one of the primary driving forces in national forest management, and the research programs designed to support this policy. For many, this is a radical departure from the traditions of forestry and silviculture, in large part because of the shift in emphasis from timber harvesting to management for a variety of benefits.
The acorn is not only a symbol of fall, but the nuts are a baseline indicator of the current and future health of the forest ecosystem. U.S. Forest Service researchers studying acorns find a bounty of acorns indicates healthy trees and a plentiful food supply for the creatures that form the base of the forest food chain. Research Ecologist Katie Greenberg and Forestry Technician Jacquelyne Adams explain how the study of acorns can gauge the current and future health of the forest ecosystem.
Scientists trying to save the hemlock tree from the woolly adelgid, an invasive insect, hope integrated pest management (combining pesticides, the release of predator beetles, and the development of hybrid trees resistant to the insect) may be the answer. Project Leader Bud Mayfield discusses measures being taken to preserve hemlock populations.
The Center for Forest Disturbance Science of the US Forest Service Southern Research Station uses remote flight to study smoke plumes from wildland fires.
The U.S. Forest Service, Forest Inventory and Analysis unit provides the research that helps Brown-Forman Cooperage locate its new mill in a small town and boosts the local economy.
Forest Service scientist Hilliard Gibbs conducts research on the extended germination of ramps, cohosh, and other forest plants.
