| The Mature Hardwood
Forest Set-Aside Area. |
The origin of the Set-Aside Program on the Savannah River
Site (SRS) can be traced to 1951, when the Atomic Energy
Commission-Savannah River Operations Office (AEC-SROO) invited
the Universities of Georgia (UGA) and South Carolina to
conduct land-use surveys and ecological inventories at the
newly acquired Savannah River Plant (SRP). These surveys
and inventories gathered baseline ecological data from different
habitats on the SRP to monitor ecological impacts from plant
construction and operation. As part of the land-use survey,
UGA scientists selected representative examples of the ecological
habitats known to exist on the SRP, so that research projects
could be conducted in them. Early recognition by the AEC
of the value of these ecological habitats set the stage
for the present SRS Set-Aside Program.

habitat, represented in the Set-Aside Program, is becoming
increasingly rare in the southeastern United States. |
In 1967, the Savannah River Ecology Laboratory (SREL) selected
seven areas on the SRP and recommended that the AEC set
these aside as examples of the various ecosystems on the
SRP. In 1968, these areas, combined with three habitats
previously allocated to UGA, were granted set-aside status
and officially were called SREL Reserve Areas. These ten
areas, totaling 892 acres (0.5% of the SRP), permanently
were set aside by the manager of the AEC-SROO to represent
and protect examples of the major plant communities and
habitat types within SRP boundaries. These areas, protected
from public access, forest management, and most routine
Site activities, offered locations for long-term ecological
research as well as "reference" sites for collecting
data to compare with other areas of the SRP that could be
impacted in some way by Site operations. That same year,
the Society of American Foresters (SAF) registered two Natural
Areas on the SRPthe Boiling Springs Natural Area and
the Scrub Oak Natural Area. These two areas, added to the
ten SREL Reserve Areas, gave the SRP 12 areas recognized
as part of the SRP Habitat Reserve System.

In 1988, a document was prepared for SREL describing the role that
Set-Aside Areas play in natural resource management on the
SRS and a proposal was submitted to DOE by SREL to expand
the program by adding long-term study sites, additional
representative habitat areas, and SAF Natural Areas. In
1989, as a result of this proposal, the DOE approved the
addition of 18 areas to the program, resulting in 30 Set-Aside
Areas totaling 14,005 acres (5,668 ha), or 7% of the land
on the SRS. The 30 Set-Aside Areas encompass the eight vegetation
communities characteristic of the SRS: old-fields, sandhills,
upland hardwoods, pine forests, bottomland forests, swamp
forests, Carolina bays, and fresh water streams and impoundments.
These 30 areas are designated as DOE Research Set-Aside
Areas.

SREL serves as custodian for the 30 DOE Research Set-Asides
and provides day-to-day ad-ministration of the SRS Set-Aside
Program, including boundary maintenance and coordination
of the activities of SREL and other contractors within and
around the Set-Aside Areas. The Set-Aside Program receives
guidance and technical advice from the Set-Aside Task Group,
which was established in 1992 under the auspices of the
Natural Resources Coordinating Committee (NRCC) to assist
DOE in the management of the natural resources of the SRS.
The Set-Aside Task Group ensures that the Set-Aside Program
meets the objectives of the "Set-Aside Protection and
Management" Plan, which stipulates that:
- Set-Aside Areas are for research, not for intensive
management objectives,
- Set-Aside Areas should receive as little management
as possible,
- Set-Aside Areas should be protected to remain as natural
as possible with little or no human influence, and
- Set-Aside Areas are primarily for nonmanipulative research,
with no research being conducted in a Set-Aside Area that
would alter the long-term value of the Set-Aside.
Purpose of the DOE Research
Set-Aside Areas
 |
| Rare and sensitive
plants are found in Set-Aside Areas. |
The 30 Set-Aside Areas serve a number of functions on the
Savannah River Site, including the following:
- Set-Aside Areas serve as sources of "control"
data for compliance-mandated environmental monitoring
activities because they are not associated with normal
Site operations and forest management activities.
- Set-Asides serve as reference "clean" areas
which can be assessed for appropriate reference or "end-point"
species used in ecological risk assessments of potentially
contaminated areas.
- Set-Asides provide baseline information on how SRS natural
communities are structured and how they function in a
setting relatively unimpacted by human activities, thus
providing targets for how restoration/remediation activities
should proceed to restore disturbed and contaminated areas
to functioning biological systems.
- Set-Asides provide areas in which to conduct long-term
ecological research, to enhance our understanding of how
communities on the SRS function and how these communities
may be impacted by human activities.
- Some of the Set-Asides have been documented
to contain significant archaeological sites and the "Set-Aside"
status of these Areas serves to preserve and protect these
cultural resources.
- Set-Aside Areas provide natural settings
for educational and public outreach activities.
