Invasive Plant Grant Will Use Research Park and Other Sites - Michael Huston, Environmental Sciences Division, ORNL

A non-profit corporation in Oak Ridge, Interdisciplinary Solutions for Environmental Sustainability, Inc., has received a 3-year grant from the U.S. Environmental Protection Agency to conduct research on patterns of invasion by exotic plant species on the Oak Ridge Reservation, Great Smoky Mountains National Park, and the Big South Fork National Recreation Area. Invasive exotic species are a major problem for land managers in national parks, national forests, and other lands used for agriculture, forestry, recreation, and conservation. These plants, which include many well-known weeds, are changing our natural landscape and crowding out native species. All federal agencies are required by Executive Order to take measures to reduce the impacts of exotic species on the lands they control. Research at Oak Ridge will involve surveys over the entire Research Park to determine the distribution and impact of exotic plants, as well as experiments to determine how natural processes can be used to control their spread and impact.

Soil Carbon Dynamics - Tom Ashwood, Environmental Sciences Division,ORNL

Chuck Garten and Tom Ashwood of the Environmental Sciences Division at ORNL are working on a soil carbon dynamics project on the Research Park. They are sampling soils under various land cover categories. The project is funded by DOE through the Carbon Sequestration in Terrestrial Ecosystems (CSiTE) Program.


Native Grass Meeting -- J. W. Evans, TWRA

The next Native Grass Meeting will be November 14 (Wednesday) from 9–11 a.m. We’ll meet at the Tennessee Department of Environment and Conservation Facility on Emory Valley Road. Topics include a presentation by a Sharp Brothers Seed representative and a discussion of genetic considerations led by Chris Fry, Maryland.


Light Emitting Diodes on Bethel Valley Road

As you drive down Bethel Valley Road, note the new traffic lights being installed at the entrance to the Spallation Neutron Source Site. New traffic signals were raised over the weekend at the junction of Chestnut Ridge Road and Bethel Valley Road. The new lights represent an investment by ORNL and the Spallation Neutron Source (SNS) Project in the best available energy efficient technology, reports Jonathan Scurlock (ORNL Environmental Sciences Division) and Wayne Parker (ORNL Engineering Division). They are made out of arrays of light emitting diodes (LEDs), which are extremely energy efficient and have a very long life. LED traffic lights typically consume less than 10 watts of electric power and replace the old style "incandescent bulb" lights that are rated at around 100 watts. Many cities in the USA and worldwide are in the process of replacing their traffic lights with LED units, which save energy, save on carbon emissions and other air pollution, and yield major savings on both operating and maintenance costs. The new LED lights are thought to be the first in the state of Tennessee.


Aquatic Recovery on the Oak Ridge National Environmental Research Park - Mike Ryon, Environmental Sciences, ORNL. A two-pager information sheet on aquatic recovery has been prepared and is available for distribution. Email your mailing address to Pat Parr at It will also be on the Research Park Web site soon.

Free-Air CO2 Enrichment Data Available - Bob Cushman (ORNL)

The Carbon Dioxide Information Analyses Center (CDIAC) has begun to archive and distribute data from the Oak Ridge National Laboratory FACE (Free-Air CO2 Enrichment) research site. The first of the ORNL FACE data sets available from CDIAC's FACE web site, provided by Jeffery Riggs (ORNL Integrated Operations Support Division), Lynn Tharp (ORNL Computational Sciences and Engineering Division), and Richard Norby (ORNL Environmental Sciences Division) includes weather-related data (air temperature, relative humidity, solar radiation, soil temperature, precipitation, wind) from 1999–2001; future data sets will cover measured CO2 concentrations in the experimental rings, tree basal area, and leaf production.

Southeast Exotic Pest Plant Council Symposium

“Rescuing Our Natural Heritage,” Wednesday, April 3–Friday, April 5, 2002, Bell South Auditorium, Nashville, Tennessee. Conference objectives are to (1) exchange information and technology leading to cost efficient management of invasive exotic species in natural areas; (2) provide a forum for participants to develop networks of mutual assistance; and (3) facilitate interdisciplinary dialog between policy makers, land managers, and researchers. Participants are invited to submit proposals for oral presentations or posters at the Conference. Contact Richard Clements at or Pat Parr at for more information on requirements and formatting. Updates on the symposium, a registration form, and an agenda will be posted soon at the SE-EPPC Web site at
