Dear Mr. Johnson:
Subject: Report for Threatened and Endangered Species Survey for Schweinitz's Sunflower
(Helianthus schweinitzii).
Vulcan Materials Company, Gold Hill Quarry,North Carolina
CEC Project 305-178
Civil & Environmental Consultants, Inc. (CEC) is pleased to provide Vulcan Materials Company
(Vulcan) with our assessment of potential habitat for the Federal and State Listed Endangered
Species, Schweinitz's Sunflower(Helianthus schweinitzii), located at 5300 Gold Hill RD, GOLD
HILL NC 28071 encompassing an approximately 143 acre tract of land corresponding to PIN #
66032629690000, (Project or Project Area) (Figures 1 through 5).
1.0 BACKGROUND
As a result of a letter sent to Vulcan, from the North Carolina Department of Environmental
Quality (NC DEQ) dated August 31, 2020 regarding comments from the United States Fish and
Wildlife Service (USFWS), about the possible presence of Schweinitz's Sunflower (Helianthus
schweinitzii) onsite, CEC was retained by Vulcan, to perform a targeted Threatened and
Endangered Species Survey at the above referenced site. This survey was performed by qualified
staff during the appropriate survey window as mandated by the USFWS office in Asheville,North
Carolina.

2.0 MATERIALS AND METHODS
Lead Investigator: David Campbell
Education: BSc, Biology, Trent University, 1998
MS, Biology, University of Nebraska, 2021
Experience: Project Manager, Civil&Environmental Consultants,May 2020-present.
Senior Scientist, Habitat Assessment &Restoration Professionals, 2003-
2020.
Research Associate, North Carolina Natural Heritage Program (NCNHP),

Experience Surveying
For Subject Species:
• Over 17 years of experience surveying for Schweinitz's Sunflower
(Helianthus schweinitzii) as Botanist and then Senior Botanist under the
direction of Dr. James F. Matthews of Habitat Assessment&
Restoration Professionals(HARP). Surveys and monitoring performed
for private companies,North Carolina Department of Transportation
(NCDOT),North Carolina Natural Heritage Program(NCNHP), and
South Carolina Department of Natural Resources(SCDNR).
• Assisted the City of Rock Hill,in relocation and transplant of impacted
populations of Schweinitz's Sunflower in York County, SC.
Morphology and Habitat Description
Morphology: Schweinitz's sunflower is a perennial that regularly grows approximately 6'/2 feet
tall (though it can be shorter if young or injured) and can occasionally reach heights of 16 feet. It
has thickened roots that are specially designed to store starch. The stem is purple, and the upper
third bears secondary branches at 45-degree angles. The leaves are arranged in pairs on the lower
part of the stem but usually occur singly on the upper part. Leaves grow out from the stem at a
right angle, and the tips of the leaves tend to droop. The leaves are thick and stiff, with a rough
upper surface. They have broad spiny hairs that are directed toward the tip, and soft white hairs
cover the underside. The plant produces small yellow flowers. Schweinitz's sunflower blooms
from late August until frost. It's able to colonize through the dispersal of seeds that readily
germinate without a dormant period. In good conditions, it can grow 3 to 6 feet in a year and can
live for decades (https://www.fs.fed.us/wildflowers/Rare_Plants/profiles/).
Habitat: Clayey soils of woodlands and roadsides, in areas formerly with Post Oak-Blackjack Oak
savannas, xeric oak-pine woodlands, or "Piedmont prairies," now primarily on mowed road or
powerline rights-of-way. Piedmont of nw. NC and nc. SC, primarily within 100 km of Charlotte,
NC (Weakley 2012); the project area conforms to the region outlined by Weakley and Houk,
(1994) (Figures 1, 2, and 3). In addition, Smith (2008), noted that among the various series

preferred by Helianthus schweinitzii, one of those is Enon, which does occur in one relatively
small section of the project area, but does not overlap with any of those open areas that were
deemed to contain plausibly suitable habitat(Figures 4A, 4B & 5).
Reference Sites
Prior to the onsite visit of September 4, 2020 CEC staff acquainted themselves with Schweinitz's
Sunflower appearance in the field and habitat preferences by visiting known reference sites at the
Blackjacks Heritage Preserve in Rock Hill, South Carolina.
3.0 ONSITE VISIT
On September 4, 2020 CEC Scientist David Campbell, Botanist, and CEC Field Technician Caleb
Cantrell, performed an onsite assessment of the project area. The approximately 143 acre tract is
comprised mostly of wooded areas undergoing secondary succession;there are also some Loblolly
Pine(Pinus taeda)plantings occurring throughout. Dominant tree species in upland areas include
Tuliptree (Liriodendron tulipifera), Southern Red Oak (Quercus falcata), Black Oak (Quercus
velutina), White Oak (Quercus alba), Mockernut Hickory (Carya tomentosa), Red Maple (Acer
rubrum var. rubrum), and Black Gum (Nyssa sylvatica). Shrubs and smaller tree species present
are Flowering Dogwood (Corpus florida), Redbud (Cercis canadensis), Black Huckleberry
(Gaylussacia baccata), and Beaked Hazel (Corylus cornuta). Herbaceous diversity is moderate
with Christmas Fern (Polystichum acrostichoides), Ebony Spleenwort (Asplenium,platyneuron),
Southern Ground-cedar (Diphasiastrum digitataum), Spotted Wintergreen (Chimaphila
maculata), Indian Pipes (Monotropa uniflora), Roundleaf Tick-trefoil (Desmodium
rotundifolium), and Green Needlegrass (Piptochaetium avenaceum). A large pond with several
species of emergent plants including Rushes (Juncus spp.), Sedges (Carex spp.), and Water-lilies
(Nymphaea spp.) occurs in the northern section of the project area(Please see Attachment A).
Embedded within the wooded areas were four sites of open glade/old field successional habitat
types (Open Sites 1-4) (Figure 5). As these were areas of abundant sunshine, special survey
emphasis was placed on them as being potentially suitable for Schweinitz's Sunflower(Helianthus
schweinitzii). All four open areas were dominated by graminoids such as Johnsongrass (Sorghum
halepense), Purpletop (Tridens flavus), Orchard Grass (Dactylis glomerata), Crowngrass
(Paspalum spp.), and Broomsedge (Andropogon virginicus). Non-graminoid herbaceous species
were also present in lower numbers and included Chinese Lespedeza (Lespedeza cuneata),
Goldenrod (Solidago spp.), Common Milkweed (Asclepias syriaca), and Yellow Goatsbeard
(Tragopogon dubius). Although there was a very small area of potentially suitable habitat around
the margins of Open Site 3, despite intensive searching, no Schweinitz's Sunflower (Helianthus
schweinitzii)were located at Open Site 3.In addition,no Schweinitz's Sunflower or suitable habitat
were found within or around Open Sites 1, 2, and 4 (Attachment A).
Finally, open roadside areas along the south-western portion of the project area along Gold Hill
Road East were investigated for the presence of sunflowers or suitable habitat. Sites along the
roadside were either intensively maintained with planted Fescue Grass (Festuca spp.) or were

heavily shaded and dominated by woody species such as Chinese Privet (Ligustrum sinense),
Winged Elm (Ulmus alata), Shining Sumac (Rhus copallinum), and Sweetgum (Liquidambar
styraciflua). No Schweinitz's Sunflower(Helianthus schweinitzii) or suitable habitat were found
at these sites (Please see Attachment A).
4.0 FINDINGS
As a result of the present investigation,no Schweinitz's Sunflower(Helianthus schweinitzii),were
found onsite. Although very small areas of potentially suitable habitat exist in one area(Open Site
3),no sunflowers (Helianthus spp.)of any kind were found to occur there(Figure 5 &Attachment
A). Special emphasis was placed on the investigation of potentially suitable areas of habitat such
as roadsides and open fields, but these were found to be unsuitable due to shading, and/or
overcrowding by woody transgressives as well as the presence of many non-native and aggressive
herbaceous species occurring in large numbers,to the detriment of the native flora. Therefore,we
feel that work undertaken in the project area will produce no effect in regards to the potential
presence of Schweinitz's Sunflower(Helianthus schweinitzii) at this site (Please see Table 1).
