PARK RESEARCH AND USERS

Carbon Dioxide Information Analysis Center (CDIAC) - Tom Boden, Environmental Sciences Division, ORNL

This center, located at Oak Ridge National Laboratory, serves as the data archive for the AmeriFlux Network, a network comprised of approximately 50 sites located in North, Central, and South America that measures carbon, energy, and water vapor fluxes continuously. One flux tower, operated by National Oceanographic and Atmospheric Administration’s Atmospheric Turbulence Diffusion Division, is situated at Walker Branch Watershed on the Oak Ridge National Environmental Research Park. Last year, CDIAC received over 25,000 requests for AmeriFlux data and information from students, researchers, and individuals in 24 countries. Web information on the Carbon Dioxide Information Analysis Center is located at http://cdiac.esd.ornl.gov/.

NATURAL RESOURCES AND MANAGEMENT

Sara Drake, University of Tennessee student working at ORNL with Mark Burnette and Larry Gray of ORNL’s Plant and Equipment Division, initiated efforts the end of March to eradicate Chinese privet on the Oak Ridge Reservation. Chinese privet has been identified as one of the top problem non-native invasive plant species on the reservation. Chinese privet along sections of Jones Island Road were treated with a foliar application of roundup.

PARKNET UPDATES

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 http://nerp.esd.ornl.gov/.

Nevada Test Site (NTS) Environmental Research Park Vegetation Classification - Bob Furlow, NTS Research Park Manager

A vegetation classification effort of the Nevada Test Site (NTS) Environmental Research Park has just been completed and the final report published. Mapping of vegetation was initiated by first identifying landforms and delineating their boundaries. Boundaries of landforms with similar physical and biological properties were then verified in the field and adjusted as needed to delineate ecological landform units. Over 1500 of these units were sampled over a three-year period from 1996-1998. Boundaries of the ecological landform units were digitized into a GIS system and linked with field data collected at these sites. Based on an iterative clustering process, 10 vegetation alliances and 20 associations were recognized as occurring on the NTS. Alliances and associations were named after the predominant tree or shrub species based on relative abundance and according to Federal Data Committee and Ecological Society of America conventions. The report describes the vegetation alliances and associations. It also provides summaries of various environmental data, such as soil texture, elevations, slope, biotic crusts, precipitation, etc. Analyses are presented including species diversity and species richness, presence of annual native and introduced vegetation, and interspecific associations of species. Distributions of the predominant species are shown in a series of maps. The report includes extensive appendices including a list species that occurs on the NTS, species abundance and frequency, and summary data for alliances and associations. Contact Dr. Kent Ostler, Bechtel Nevada, for more information or to obtain a CD of this report. His e-mail address is ostlerwk@nv.doe.gov, or he can be reached by phone at 702/295-0393.

COMMUNITY OPPORTUNITIES

Community Adventure Rambles, a series of nature walks, will be offered during April and May on the Department of Energy's Oak Ridge Reservation.

PRESENTATIONS

Two researchers presented papers resulting from their work on the Oak Ridge Reservation at the annual symposium of the Southeast Exotic Pest Plant Council in Georgia March 21-23. Patrice Cole, a graduate student in the Department of Ecology and Evolutionary Biology at The University of Tennessee, Knoxville (co-authors:  Jake F. Weltzin of The University of Tennessee, Knoxville, and Michael A. Huston of ORNL), presented a paper on "Identifying the Habitat Characteristics of the Non-native, Invasive Grass, Microstegium vimineum."

Sara Drake, an undergraduate student in the Department of Ecology and Evolutionary Biology at The University of Tennessee, Knoxville (co-authors: Jake F. Weltzin of The University of Tennessee, Knoxville, and Pat Parr of ORNL), presented "Assessment of Non-native Invasive Plants on the National Environmental Research Park at Oak Ridge National Laboratory."

Oak Ridge National Laboratory’s Environmental Sciences Division staff played prominent roles in the international Fractured Rock Conference that was held in Toronto, Canada, just this past week. The conference focused on flow and transport issues in fractured rock systems. Tom Early, as part of the organizing committee, was instrumental in getting the conference off the ground and generating interest from the scientific community. It was a great event; over 460 people were present from about 17 countries and many were the "shakers and movers" in the research field. Geri Moline and Phil Jardine made oral presentations, and Melanie Mayes presented a poster. Tom reports that he received many favorable comments about the talks, and Melanie's poster received a great amount of interest. Tom sensed that the scientific community represented at the conference was very impressed with the fractured rock research and development being done at the Oak Ridge National Laboratory.
