Herbivory on Broadleaf Plants - Mac Callaham, United States Forest Service

There was some neat stuff going on at the ORR this past summer! The work of one of the summer intern students, Bridgette Boudreaux, University of Louisiana at Lafayette, was jointly advised by Paul Hanson and Bill Hargrove (ORNL) and Mac Callaham (USFS). She worked on a project aimed at quantifying insect herbivory on American beech and red maple in the Walker Branch Watershed, Throughfall Displacement Experiment plots. Her preliminary findings suggest that understory red maples experienced greater levels of insect herbivory in the enhanced throughfall plots relative to the ambient and reduced throughfall treatments during the early part of the growing season. American beech showed a similar response with evidence of increased herbivory levels in the wet plots throughout the growing season. The work Bridgette did this past summer should also contribute substantially to a new, highly accurate and automated method for the measurement of herbivory on broadleaf plant species currently under development by Bill Hargrove. See more on the Throughfall Displacement Experiment at: Funding for the Walker Branch Throughfall Displacement Experiment comes from the DOE's Biological and Environmental Research Program.


Native Grass Restoration on the Oak Ridge Reservation - Tennessee Department of Environment and Conservation’s Doug McCoy, along with Tennessee Wildlife Agency officers Dick Conley and Jim Evans, hosted an informal native grass workshop in Oak Ridge on Friday, September 14. Interest in native grass restoration and establishment on the Oak Ridge Reservation is high as indicated by the participation from individuals from the Department of Energy, Oak Ridge National Laboratory, BWXT-Y12, Bechtel Jacobs, TVA, Great Smoky Mountains National Park, Oak Ridge Associated Universities, Native Gardens, and various consults. Tennessee Wildlife Resources Agency will be converting many of the fescue fields in the Three Bend Scenic and Wildlife Refuge (on the reservation) to native grasses. Additionally, ORNL is planning some demonstration plots along Bethel Valley Road, Bechtel Jacobs has plans for use of native grasses where possible in waste management areas, and the Spallation Neutron Source Project is working to incorporate natives into landscaping planning. The representative from Sharp Brothers Seed was unable to come due to impacted flight schedules, but Dick Conley gave a good overview of types of grasses, planting, and expectations. The next meeting will include a presentation from Sharp Brothers and discussion on genetic considerations. If you would like to be on the electronic mailing list for information about future meetings, please send me your name, email, affiliation, and phone number (if you attended the last meeting you are already on the list). Send to Information will also be included in Park Notes.


Several ORNL Environmental Sciences Division staff attended the annual Ecological Society of America meeting in Wisconsin during August. Of special note was an article in Science where ORNL researcher, Rich Norby, and the Free-Air Carbon Dioxide Enrichment (FACE) experiment was featured. Check out


Dale, V. H., and Haeuber, R. A. (editors). 2001. Applying Ecological Principles to Land Management. New York, Springer-Verlag. Virginia Dale, ORNL Environmental Sciences Division, also contributed three of the chapters in this edited book.


Carbon Dioxide Information Analysis Center (CDIAC ) Products: Ambient atmospheric CO2 data through 2000 from Mauna Loa, Hawaii, contributed by Charles David Keeling and Timothy Whorf (Scripps Institution of Oceanography), have been put on-line [as updated numeric data package NDP-001 ( and as an updated entry in "Trends Online" (] by CDIAC's Tom Boden of ORNL.

CDIAC has added to its Temperature chapter of "Trends Online" a database titled "Monthly surface air temperature time series area-averaged over the 30-degree latitudinal belts of the globe" (, contributed by K.M. Lugina (St. Petersburg State University, St. Petersburg, Russia), P.Ya. Groisman (National Climatic Data Center, Asheville, North Carolina), K.Ya. Vinnikov (University of Maryland, College Park), and V.V. Koknaeva and N.A. Speranskaya (State Hydrological Institute, St. Petersburg, Russia). The data, graphs, and associated documentation were prepared for on-line publication by Daria Beth Scott, a summer intern at CDIAC from St. Cloud State University in St. Cloud, Minnesota, and CDIAC's Dale Kaiser of ORNL.

The Oak Ridge National Environmental Research Park was designated by the Department of Energy in 1980 and is one of a network of seven National Environmental Research Parks. It is an Oak Ridge National Laboratory User Facility. The Oak Ridge National Environmental Research Park was designated an international biosphere reserve in 1989. It is also a unit member of the Southern Appalachian Biosphere Reserve and part of the Southern Appalachian Man and the Biosphere (SAMAB) Cooperative.
