OU2 Trench Area Reforestation Program
2006 Status Report
National Starch & Chemical Company
Salisbury, North Carolina
Dear Mr. Bornholm:
On behalf of National Starch & Chemical Company (NSCC), Blasland, Bouck & Lee,
Inc. (now known as ARCADIS U.S., Inc. [ARCADIS BBL]) has prepared this letter to
present monitoring results for the 2006 OU2 Trench Area Reforestation Program for
the Cedar Springs Road Plant Site (Site) in Salisbury, North Carolina (Figure 1 ). The
objectives of the reforestation project include 1) create a self-sustaining vegetative
canopy cover to decrease infiltration of surface water to groundwater; 2) promote
species diversity of tree and shrub stratum typical of surrounding areas; and 3)
provide additional function of wildlife habitat.
During the initial reforestation activities conducted in 2005, approximately 1,800 bare
root saplings were planted in a 10-foot by 10-foot grid pattern. Trees planted
included approximately 1,000 scarlet oaks (Quercus coccinea), 400 to 500 loblolly
pines (Pinus taeda), and 300 black locusts (Robinia pseudoacacia). Figure 1
presents a landscape plan for the initial planting event.
Adaptive management is used to direct the OU2 Trench Area Reforestation Program
towards achieving the aforementioned objectives through monitoring events to
evaluate project status relative to project objectives, implementation of maintenance
activities, and adjusting management strategies based on monitoring event results.
Maintenance activities for the OU2 Trench Area Reforestation Program are currently
focused on the reduction of invasive species occurrence and increasing growth and
survival rate of planted trees.
Imagine the result

This letter discusses data collection methods, presents monitoring event results, and
provides recommendations for future adaptive management activities for the OU2
Trench Area Reforestation Program. On May 16, 2006 and November 16, 2006,
ARCADIS BBL conducted quantitative sampling of planted trees and qualitative
evaluation of reforestation area conditions. Field personnel applied deer repellent to
planted deciduous trees and spot-sprayed herbicide to target invasive species on
May 16, 2006 and July 11, 2006. Field personnel pruned saplings, as needed,
during the May, July, and November events to promote vertical growth.
Methods
ARCADIS BBL implemented methods described below during monitoring events in
2006 to collect data regarding planted tree growth in OU2 and general conditions of
the reforestation area. Qualitative and quantitative data was collected to evaluate the
condition of planted trees. Qualitative data was collected to evaluate overall
reforestation area condition.
Sample Design
The project area was divided into six management zones of approximately similar
area. The corners of each management zone were uniquely designated as "A", "B",
"C", or "D". Figure 2 presents management zone orientation and identification. Data
regarding height, condition, and intensity of deer browsing for approximately one-
third of planted trees were collected from a random sample population in each
management zone. Data were collected from a randomly selected starting point in
the management zone and proceeded with every third tree. The staring point was
randomly selected by noting the second hand position when sampling began and
following the procedure listed in Table 1.

Data Collection Procedures
Data collection for planted trees included the following.
•
•
•
Height
Tree height was measured to the nearest inch, from the ground surface to the highest
live portion of the plant. Dead plants were not measured.
Condition
A qualitative evaluation of plant health was recorded. Plant condition was categorized
as dead, poor, fair, good, or excellent. Table 2 provides a qualitative description for
each category used to evaluate tree condition.
Deer Browsing
Intensity of deer browsing was evaluated and categorized as none, mild, moderate, or
heavy. Table 3 provides a qualitative description for each category used to evaluate
browsing intensity.

Qualitative evaluation of conditions in the reforestation area was also conducted.
This evaluation included an inventory of tree and shrub species in the reforestation
area, documentation of natural recruitment, identification of areas dominated by
invasive species, effectiveness of invasive species management practices, and
photo-documentation of the reforestation area. Observations of wildlife use were also
noted.
Results
The following sections summarize monitoring events results for 2006. Table 4
presents data for the May and November 2006 monitoring events.
Planted Tree Evaluation
Data regarding percent survival, growth, condition, and intensity of deer browsing for
trees planted during 2005 are presented below.
Percent Survival
The survival rate for planted trees in the reforestation area was 85.6 percent during
the 2006 growing season. Survival rates in management zones ranged from 76.7 to
96.4 percent and indicate similar viability of planted trees in management zones. No
areas of mass natural mortality were observed. Species-specific survival rates for
black locust, loblolly pine, and scarlet oak appear similar.
It should be noted that numerous loblolly pine trees planted in Management Zone 6
were impacted by a change in land use following the 2005 planting event (Figures 3
and 4) which resulted in a loss of approximately 40 percent of trees initially planted in
Management Zone 6. This decrease in survival is reflected in the May 2006
monitoring data and do not reflect natural death of trees in these areas. Furthermore,

survival rate data for Management Zone 6 during the November 2006 monitoring
event excluded trees included in the area of modified land use. Future data collected
for the reforestation area will not include data regarding trees planted in the area of
modified land use.
Growth
Site-wide average tree height at the end of the 2006 growing season was 31.9
inches and management zone-specific average tree height ranged from 23.5 to 47.6
inches. Species-specific average tree height and average growth was as follows:
• Black locust-45.7 inches average height; 15.8 inches average growth .
• Loblolly pine -39.3 inches average height; 17.9 inches average growth .
• Scarlet oak 22.1 inches average height; 2.2 inches average growth .
Average growth of planted trees during the 2006 growing season was approximately
10 inches. Average growth within management zones followed trends displayed by
species-specific data, and varied between management zones based on the
composition of trees planted (i.e., lower growth rates in Management Zones 2, 3, and
4 due to high percentage of scarlet oak planted in these areas).
Condition
Health of planted trees in the reforestation area was satisfactory, as indicated by the
96.5 percent of planted trees were assessed to be in fair condition or better.
Condition was similar between management zones and species.
Deer Browsing Intensity
Evidence of deer browsing was observed on approximately 40 percent of planted
trees in the reforestation area during the May 2006 monitoring event. However,
evidence of deer browsing was less than 6 percent in all management zones during
the November 2006 monitoring event. Furthermore, data indicate that loblolly pines
are preferentially avoided, although a few cases of deer rubs were qualitatively noted
(Attachment B).

General Reforestation Area Conditions
Project area conditions are generally good. Natural recruitment has augmented
species composition and density of trees in the reforestation area. Additionally,
invasive species prevalence in the reforestation area decreased throughout the 2006
growing season.
Natural Recruitment
Native tree/shrub species naturally recruiting in the reforestation area are presented
in Attachment A. Seedlings and saplings of these species appear healthy and were
abundant throughout the reforestation area. At the end of the 2006 growing season,
some naturally recruited plants were larger in height and diameter at breast height
than planted trees. Figure 3 depicts areas of relatively concentrated natural
recruitment by native species.
Invasive Species
Invasive species identified for control included: Japanese honeysuckle (Lonicera
japonica), wild blackberry (Rubus ursinus), tree of heaven (Ailanthus altissima), and
bittersweet nightshade (Solanum ducamara). Areas dominated by these species are
indicated on Figures 3 and 4. Routine application of herbicide to these species during
adaptive management activities appears to have reduced the abundance of invasive
species in the project area.
Observations of wildlife use included visual sightings of turkey and six-lined
racerunners, as well as numerous indications (e.g., observations of trails, beds, rubs,
scat) of white-tailed deer.
Attachment B presents photo-documentation of reforestation area conditions during
2006 and observations of wildlife use.
Conclusions and Recommendations
Percent survival and condition of planted trees in the reforestation area are
satisfactory for growth of a canopied tree cap in OU2. No species-specific or
management zone-specific negative trends were noted. Therefore, no changes to the
management strategy are necessary to address tree survival or condition.

Growth of planted trees was highest for loblolly pine and black locust, but lower for
scarlet oak. Such patterns of growth are expected as loblolly pine and black locust
are early colonizer species in an old field succession system, as is present in the
OU2 Reforestation Area, and are adapted to grow rapidly in full-sun, drier conditions.
Increased growth of these species in comparison to scarlet oak is expected.
Therefore, no changes to the management strategy are necessary to address tree
growth.
Deer browsing in the reforestation area decreased substantially between the May
and November monitoring events. The observed decrease is likely due to periodic
deer repellent applications to planted trees throughout the growing season.
Furthermore, deer are selectively avoiding browsing on loblolly pines in the
reforestation area.
Prevalence of invasive species in the reforestation area decreased during the 2006
growing season (Figures 3 and 4). This decrease in invasive species prevalence is
likely due to periodic herbicide application throughout the growing season.
Based on the above observations and conclusions, ARCADIS BBL recommends the
following for OU2 Trench Area Reforestation Maintenance and Monitoring Program
in 2007.
•
•
•
Continue spot application of herbicide to invasive species in the reforestation area .
Herbicide applications should occur twice a year, once in late spring and once in
early fall.
Continue application of deer repellent to deciduous trees planted in the
reforestation area. Deer repellent applications should occur twice a year, once in
late spring and once in early fall. Deer repellent application need not occur for
loblolly pines in the reforestation area.
Exclude project area from mowing activities. This will maintain a tall herbaceous
layer that will provide cover for seedlings and saplings, thereby reducing predation,
and will retain moisture while the tree canopy develops. Postponing mowing
activities will also avoid damage to seedlings and trees that are hidden by the taller
herbaceous cover, thus promoting natural recruitment.

• Conduct qualitative and quantitative data collection during fall 2007 maintenance
activities. Data collection should include the same elements conducted during
2006. Additionally, quantitative data regarding the height, number, and species of
naturally recruiting saplings in the reforestation area that are greater than 36
inches in height should be recorded.
Data collected during subsequent monitoring events will be used to evaluate the
status of the OU2 Reforestation Area relative to project objectives, assess the
effectiveness of current management practices, identify areas not performing as
expected, and develop alternative strategies for improvement, if warranted.
