Oriental Bittersweet Treatment - Larry Pounds (ORNL plant ecology consultant)

Oriental bittersweet plants in Research Park Natural Area 2 were treated August 28, 2001, by Larry Pounds. Last year, 469 plants were located and removed from the site through an invasive plant project by teachers from Appalachian Resources Commission. Surveys by the 2001 teacher team located 136 plants at the site this year. Last year, this was the only known site on the Oak Ridge Research Park with oriental bittersweet.

A new site with oriental bittersweet has been identified adjacent to a firing range within the Southeastern Couriers Training Facility. Larry Pounds discovered the additional site during a walkover August 23, 2001, as part of a survey for rare plants. There are currently plans to clear the small forested area to expand the firing range. This clearing should result in the eradication of the bittersweet at this second site.

Deer Hunts Start in October - Warren Webb, Environmental Sciences Division, ORNL

The dates for the 2001 deer hunts on the reservation are October 20-21, November 10-11, and December 8-9, with a scouting day on the Saturday before each of the three hunt weekends. Hunts on the reservation are coordinated by Tennessee Wildlife Resources Agency and by permit only. The hunt map is available for viewing at:

REMINDER - Native Grasses Meeting by Tennessee Wildlife Resources Agency

Jim Evans and Dick Conley, Tennessee Wildlife Resources Agency, along with a representative of Sharp Brothers Seed, will be holding an information session on native grasses to address questions related to the establishment and maintenance of native grasses on the Oak Ridge Reservation. The meeting will be at the TDEC Office, Emory Valley Road, Oak Ridge, on Friday, September 14, from 9-11 a.m. If you or your colleagues are interested in attending, contact the TDEC office at 865-481-0995.


Research Park managers have received an invitation to participate in a special session on “National Environmental Research Parks” as part of the International Dixy Lee Ray Memorial Symposium to be held in October in Washington, D.C.

There was a recent story in USA Today entitled "U.S. Wildlife Finds Safe Haven on Dangerous Cold War-era Weapons Sites" (August 29, 2001) that reflects the value of sites often not thought of from this perspective. Two of the sites mentioned, Savannah River and Hanford, are Research Parks. The article can be viewed on the web at:

The Oak Ridge National Environmental Research Park is one of seven Department of Energy National Environmental Research Parks. The Parks represent seven different ecoregions across the U.S. More information is available on the DOE Research Park network (ParkNet) at


Land Use Planning Initiative Announced

The Department of Energy is taking a new approach in land use planning for the Oak Ridge Reservation. The approach will not only include looking at DOE program mission needs (which continue to be the priority for land use), but will also provide opportunities for expanded public involvement in the process. This is a refreshing approach that has the committed support of Leah Dever (Manager, Oak Ridge Operations) and U.S. Representative Zach Wamp. Oak Ridge National Laboratory will lead the effort with Frank Harris and Pat Parr as coordinators. DOE has established a focus or working group and will also hold public "town hall" type meetings throughout the planning process. Watch for updates and ways to be involved and provide your input.

Public Fall Wildflower Walk

Oak Ridge National Laboratory and the American Museum of Science and Energy will host a fall wildflower ramble at the National Environmental Research Park on Saturday, September 15. The walk, led by Larry Pounds, will offer participants the opportunity to see prairie and woods edge plants of more acid soils in Bear Creek Valley--types of plants that haven't been seen in previous walks. Participants should expect to walk about one mile, mostly on gravel, and be prepared for sun, ticks and poison ivy. Meet in the parking lot at the American Museum of Science and Energy at 8 a.m. Saturday, September 15, and the group will caravan from there to the Oak Ridge Reservation. The group should be back to the Museum by 11:30 a.m. Group size is limited to 25 and you must pre-register. Please call the Museum of Science and Energy at 865-576-3218 by Friday, September 13, to pre-register. Participants may want to bring a snack, water, and camera.


Carbon Dioxide Information Analysis Center - Bob Cushman

Carbon Dioxide Information Analysis Center (CDIAC) published "Walker Branch Throughfall Displacement Experiment Data Report: Site Characterization, System Performance, Weather, Species Composition, and Growth," contributed by Paul Hanson, Don Todd, and Gerry O'Neill (ORNL Environmental Sciences Division), Jeff Riggs (ORNL Instrumentation & Controls Division), and Mark Wolfe (Tennessee Valley Authority). The quality assurance and documentation was performed by Bob Cushman. This numeric data package provides data sets, and accompanying documentation, on site characterization, system performance, weather, species composition, and growth for the Throughfall Displacement Experiment, which was established at the Walker Branch Watershed in the Oak Ridge National Environmental Research Park to provide data on the responses of forests to altered precipitation regimes. The specific data sets include soil water content and potential, coarse fraction of the soil profile, litter layer temperature, soil temperature, monthly weather, daily weather, hourly weather, species composition of trees and saplings, mature tree and sapling annual growth, and relative leaf area index.

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.
